Hi Painless360!
So glad I found you! I've been beating my head against a wall trying to get my Crius AIO Pro V.2 to work. I'm going to start from scratch and start over. Redo firmware and everything. You have made me realize this stuff actually works! Thanks!!!!
Tim
Thanks Tim, happy flying!
Sorry to keep asking daft questions, my i6 RX is 5 volts but my 3s battery is 12 volts. Since the RX gets its power from the flight board am I right in assuming the Multiwii flight board has a bec to reduce the voltage, as the board also has 2 pins which say 5v which I would like to use for a 4.5v led headlight or would it not be wise to take a load from this point. Thanks.
+thra5herxb12s Not at all, there are loads of videos in the 'Introduction to RC' playlist that will help you with the basics - like this.. th-cam.com/video/o7L_Woeu38Q/w-d-xo.html
You sir, have saved me so much time and aggravation.
Thanks a million
Very well done video's, you take each step and put it in a way everyone can understand how to do it!
Thank You,
Thanks for the feedback. I've referred to this video myself! Handy to have a reference..
Happy flying!
Hi.
In the diagram shown in 7:14 it does not show the configuration of a H-frame, I plan to build my first Quadcopter in an H-configuration. Should I treat it as an X-Config or is there a special config for it ? Thanks!
I have a question, do you have to have the aux connected or is throttle, ail, rud, and elv enough? I dont have an aux on my receiver.
My motors are calibrated but they just dont arm :( i have a spectrum dx5e and a spectrum receiver but the motors just wont arm with the multiwii, i dont know whats wrong...
I would strongly recommend that you get a five channel receiver for any Multiwii based flight controller. You need to be able to control and select the flight mode that you are in. I'm not sure if the lack of an Aux will stop it arming but this video might help - th-cam.com/video/lc4ECi6JYX4/w-d-xo.html
Painless360 thanks a lot for your last tip! I now have my multiwii megapirate board ARMED and all the stick functions are correct!! The only problem I'm having is that it doesn't arm/unarm by turning the throttle stick to the right/left at bottom position. In my case it'll arm as soon as I give like 15% throttle on the throttle stick. And after it has been armed the motors will idle even at 0 throttle input... I also can't find a way to unarm it.
Again thanks a BUNCH for the help that you've already given me!!
You can try a few things (after that I've not got enough experience to guess!) you can try performing a ACC calibration and a MAG calibration and/or selecting #define CRIUS_AIO_PRO_V1 in the code.. Best of luck!
ACC calibration just defines the board's (level) position... MAG calibration I'm still lost on what that does.
As for defining the CRIUS_AIO_PRO_V1 I get a programing error. I referred to this in one of my previous comments.
Bruce Hitzfield If the board doesn't think it's level then it won't arm. RCgroups forums may be a good place to have a look in. I hope you get this sorted soon. Happy flying!
If your using the windows GUI then check that the boxes that assign function to your AUX1 swithing arrangement,you'll find that having the Low box checked for acro mode takes over the arming process but reading your question again I believe that "Painless360" is right in that the RCGroups site will be the place for you.The guys there are great with the MW stuff.The MAG calibration is a way of letting the chip know which way is which.You press it and rotate the copter through all axises eg: roll,flip and stand on bum and rotate (hope you know what I mean?) BUT! this has to happen within 30 seconds of pressing the calibration button ok,so try it a few times because if like me you only have a short length of wire connecting the FTDI to the copter then it takes a little working out OK.....Good luch with it and enjoy the flying

Thanks, It was very helpful but the link above about the manual of multiwii might be deleted.. Where can i download it?
Painless360, I can not seem to read the PIDs and switch info from my fc using MultiWiiConf. I hit start and read, a small led blinks rapidly but just keeps on blinking with no data to show for it? My BT ap on my cell phone works fine. Any thoughts?
Thanks, Tim
Double check the USB cable is ok. Failing that it may be the FTDI connector...
I found the adapter. Thanks! Next newbie questiion: Me receiver has the ports labeled: bat, and channels 1-6. Would these necessarily correspond to the channel numbers on the Multiwii, or is that way too simple for me to comprehend. The transmitter is a Flysky T6. Thanks for all your help!
You need to look at the manual for the radio. Each of the receiver channels relates to one of the channels on the radio - Elevator, Throttle, Aileron, Rudder etc. With the newer radios where you can decide which channel does what it can make it more complicated than it needs to be. With some radio systems they still mark up the receiver with the default channel to make connections faster.
Hope this helps.
Painless360 Many thanks! After much googling, I managed to hook everything up, hopefully correctly. I calibrated the ESCs and I am ready to program the board. I have already watched your video on that topic. I am a complete beginner when it comes to electronics and I purchased a kit from China with no instructions and that was missing most of the screws and stand offs. I love a puzzle.
Good info. I have a question about the power wire on all the ESC. So the power lead on all ESC can be hooked up on the board?
Only is they are linear UBECs on the ESCs. See How to connect the power system (ESC, BEC and power board) in your multirotor/quadcopter and How to connect OPTO ESCs and a BEC to you multirotor (KK2.0 or MWC) for more help. Let me know if it's still not clear. Happy flying!
Hi. I did try it on the grass. Manage to fly but still driftting fast to a side. Im not quite sure which side as it goes very fast drift and flip to the ground. I have checked all my motors and props. Its all installed correctly. I feels like 2 of my motors not getting much power compare the other 2. I might wrong in this. My question now is do i need to auto level the multiwii using the computer? And trim auto level after that? Im so sorry coz im newbie and just started to get into this as new hobby. Thanks in advance!
Hi Emo, if that is all ok then recheck that the artificial horizon in the MultiWiiConf responds as you'd expect and reset the accelerometers..
I'd also manually recalibrate the ESCs again too, just to be safe.
Hope it helps.
Hey Painless360, I bought a Multiwii and Megapirate v2.0 AIO board which is similar to the one in this video. Now I have have come upon the problem of how to connect my receiver to the actual board. My receiver has a +,-, and GND pin, so my question is, does it matter which of the channels is connected via the positive, negative, or ground wires? You seemed to just make sure each of them were color coordinated based upon the input into your MultiWii board.
AudioFreeeze Yes, you have to be very careful when making the connections - th-cam.com/video/LyPtzv0y5DE/w-d-xo.html and it's playlist may help answer some of your questions..
Best of luck.
Pretty cool, used your videos to base my first setup on my quad :)
My next step is to see if I can get it working with my Frsky D4R-II using PPM, seems to be something we can config on config.h as well.
I assume the first 3 pins will carry the whole signal (+, - and D2 right?) Have you tried?
+Daniel Lopes I've not done it but looks possible - www.multiwii.com/forum/viewtopic.php?f=13&t=2270
Hello, I own an old drone which has a crius multiwii se 2.5 mounted on it. It has connected a PWM receiver. I build it some years ago with the inestimable help of your playlist of videos about Crius Multiwii. I recently released a PPM receiver from another drone. Do you know where must I wire a PPM receiver to the Multiwii and how to setup in arduino? Thanks
I've never done it but there are options for PPM in the config file. Best of luck!
Hi! great video !
I use the same board as shown in the video. I flight several times without crashing my quadcopter :)
I have one question:
Why do you connect all ESCs with all 3 cables (black, red, white ) to your multiwii?
I read somewhere I have to connect only 1 red cable of all 4 ESCs to multiwii, the other 3 red cables are left over, isolated. To avoid too high voltage on the flight controller? I wired that so in my quad an it is working, but what is the difference? Is that true what I read?
I hope you answer my question.
Greetings from Austria :)
+MrBaerlibaer Watch out videos on ESC and Multirotor power systems for lots of answers..
hi
i bought a Hobbywing Quattro 20Ax4 ECS
how do i connect it to a multi wii SE 2.5
and what battery is needed for the ESC
That was a great video.Thank you so much for taking your time and posting it.
I purchased a quadcopter kit with the Multiwii board. It did not come with the FTDI adapter and I am having trouble finding the adapter without purchasing another complete flight controller board. Do you know of any place that sells just the adapter?
Search on eBay for 'FTDI Basic'
I'm having problems with my board: it seems to work as it is supposed to until I put on props and try to fly. The motors just start twitching, stuttering, and acting abnormally unless I dismount the multiwii and completely oscillate it from the vibrations of the craft. I did the best I could at balancing the props, what could be causing the issues?
I've had this problem and its been two separate issues here.
The first is that I'd flashed the ESCs with SimonK firmware and there was a bug in the KK tool that loaded the wrong firmware onto the ESCs. If you've loaded the firmware yourself - update and reload and check the versions you are using have no known issues. (Problems with HobbyKing 20A ESC after flashing with of SimonK firmware V2013-9-20 - Solution)
Second problem was due to harmonics in the frame/arms that the MWC didn't like. I used the LPF settings in CONFIG.H to remove these and fly normally.
Hope one of these is your issue and gets you flying. If not schedule a Helpout and we can take a closer look.
Painless360 What is LDF? Is it software-dampening? I did try to tape the FC to a bit of foam, but it did not help until I grabbed the FC and then the props ran smoothly.
I did not flash the ESCs with any firmware and they run smoothly with propellers (If I snap it up to near-max throttle, they buzzing/vibrating noises from I suppose unbalanced props and crap motors.) Nonetheless it seems like the ESC does what it is supposed to.
OK, sounds like you need to balance the props and motors as the vibration is too much for the controller, even with a mount. The LPF (not LDF) is a software low pass filter that removes unwanted interference in the gyro/accelerometers. I've had to do it a few times myself to get the board to handle the frame ok.
From the config.h section on LPF -
"MPU6050 Low pass filter setting. In case you cannot eliminate all vibrations to the Gyro, you can try
to decrease the LPF frequency, only one step per try. As soon as twitching gone, stick with that setting.
It will not help on feedback wobbles, so change only when copter is randomly twitching and all dampening and
balancing options ran out. Uncomment only one option!
IMPORTANT! Change low pass filter setting changes PID behaviour, so retune your PID's after changing LPF."
Try uncommenting #define MPU6050_LPF_188HZ first and if it doesn't work try the next one down until you get it.
I think I'll make a video on this as it is very handy to know..
Painless360 I've just bought a magnetic balancer it will take some time to arrive, in the mean time I think I will try that LDF settings! I sound them in the code and uncommented the 2nd one down.
I did attempt to balance the props by press-fitting a smooth round pencil into the middle, and letting it balance on the edge of my table. I then added tape to the heavier side until the heavier blade no longer preferred to swing down. I also tried balancing the base with electrical tape, but on some blades I could not get it to balance nicely, at least not with tape.
How much vibration should I expect coming from a decent setup? I just downloaded an vibration meter to my phone to see if I can quantify the vibration from the motors and props.
Painless360 In case I do need to flash SimonK firmware to the ESCs, do I need that programer shown in the video? Or can I use the FTDI adaptor? I also have a spare arduino MEGA which can probably be configured to flash other chips. I saw a video where thats what was used to flash one of those ATtiny85 chips.
hello and congratulations for the video in your opinion and what better MultiWii SE V2.5 I naze32?
thanks caluti
Umberto sf2 Thanks for the question - I've not had my hands on a Naze32 yet so can't comment. Best wishes for 2015..
thanks for the reply to her as a good year
i have multiwii 2.6 and motors MT2216 don't start. they were delivered with simonk 2-3S and i used Lipo 4s. i should use lipo 3s right?
+mag num check out the specifications for the ESCs you have. See how we did that in the 'Quadcopter building for beginners ' playlist. That should give you an answer. Best of luck!
If i dont have that green light does it mean my multiwii is bad?
Hi on my receiver neither pitch nor yaw are being picked up by the multiwii, I can see both roll and throttle being picked up. I know neither the transmitter or the receiver are the issue since I've tried each port on the receiver with a servo. Any help would be massively helpful since I'm drawing a blank.
***** I would re-flash the board and try again. Not sure what it could be if the wiring is ok.
Best of luck.
Hi
This is a great video
I'm doing a bicopter.I need information about to which pins servos are to be connected.
+Sai Kumar We've never made one here but would love to. www.multiwii.com/connecting-elements
So.. I can run power directly to the multiwii, thru the power input and removed the jumper to power the FC from the ESC. And POW it works.. but is this really the best way to do this.. another battery.. or pull it directly from the main battery?
Which Multiwii is it? If it works then go with it..
Multiwii/megapirate.... I have power now as long as it's powered through another source, but now I'm having trouble getting my controller centered even even with the max sub trim I can't get it centered. And I have one motor that seems to want to be at full blast nearly no matter what.
Normally I would recommend ESC calibration and trying another receiver but with so many problems I would start again from first principles and re-flash the board and run through all the setups again.. I've not used that board myself so haven't got any silver billets that may help..
I hope you get it sorted soon..
Can you please describe howto wire up the vbat function ?
Hi, thanks for tutorial. A question, to D8 pin can I connect a second AUX channel?
+SKYDATA Yes you can, and then use it in the MultiWiiConf program to control other things too.. Best of luck..
Can you connect all 4 ESC's if they all have a UBEC or do you only connect 1 fully then just the signal wires from the other 3??
Great video ( series ) many thanks
bigfilsing You can connect all of the power lines if the integral BEC is linear. If they are switched, just install that one. Hope that makes sense. Happy flying!
Painless360 Thanks. The next question is how to tell if its a linear or switching BEC. There seems to be a bit of confusion (on the net). I gather that UBEC's/SBEC are switching ( non linear) ( for example the HK 20A blue series we often see in your vids).
I am currently building with some EMAX 12A Simon series ( not to be confused with SimonK) and it would seem they are linear but how to be sure
www.emaxmodel.com/views.asp?hw_id=1434
My guess is they are linear but if the magic smoke comes out itll be your fault :-)
Thanks for your great vid series that's saved me hours of hunting around the net & reading ( when i should be flying)
CHeers
bigfilsing it says on the link you sent that they are Linear. the detail is in the table at the bottom of the page.
Happy flying!
Painless360 Doh ...Cant see the wood for the trees sometimes .
Thanks
bigfilsing no worries! :)
Do I need separate gimbal controller for this Multiwii SE board? (Because it has pins for camera gimbal)
Senal Weerasinghe you can use either. Best of luck!
Painless360 Could I connect gimbal motors directly to the Multiwii SE board? Thanks for advising me.
hi
I want to ask some questions?
what type of esc did you use???
where i can find a datasheet of crius 2.5 and if it is impossible to find where i need to connect the battery to power up the crius card?
the last question i need to connect the esc to another battery??
thanks
Hobbyking 20a (3a BEC) ESCs flashed with SimonK (th-cam.com/video/kA2dBD9jSVo/w-d-xo.html)
The BECs in the ESCs power the board when you plug them in (8:16)
If that doesn;'t make sense then watch th-cam.com/video/DraFgiDELjI/w-d-xo.html and th-cam.com/video/L3BnPdiK3_o/w-d-xo.html
Painless360 thanks
another question it is very important to flash the esc because i think that it's a bit difficult for me.
and
i don't understand how can i connect my esc to the pc
another things what kind of motors did you use?
this esc can replace your model?
ESC Hobbywing Skywalker 20A
The best performance from the quadcopter will come when using ESCs that are running special firmware that improves how quickly they respond the changes. This is what SimonK firmware does. It will fly without it. See my video th-cam.com/video/Sjwi_UnCLWc/w-d-xo.html fro a few ideas on motor selections..
hi can i use the dji snail escs with the mulltiwii board? or did i Need an other board for this Spezial escs? Sorry for my Bad english!
Sorry, I've not used the snail here. I've not touched a MultiWii for about two years too. Sorry I can't be more help here..
Ok! Thanks for the fast answer!
I have beginner question, i heard that I need to not connect + from ESC BEC, cause it may damage control board. How it really is?
You need to watch my other videos in the beginner series - th-cam.com/video/AIQOzFlLfJg/w-d-xo.html
Should help..
Painless360
Thanks for answer, It cleared things :)
The esc's are calibrated, is there soemthing in the softwaree i can change??
Hi! Very nice videos. I´m having problem connecting my receiver Hitec optima 7 to the Crius 2.5 and a 4 x ESC/BEC with a 3S Lipo.
I did as you explain but the receiver doesn´t work it shows a red and blue light, i don´t find any information online that explains what it means. But if i connect the signal D2 to the receiver Throttle and connect the + and - from the receiver to the pins where i connect my ESC/BEC in the crius it works ok. Do i have a damage crius board or do i do something wrong ? I get 4.6V in all the +5V pins from the board is it to low voltage? Do i have any component that is damage?
Thanks ...
+Toze Freitas Not sure what you mean, if you've connected the power the wrong way then you have probably damaged something.. Best of luck!
I was trying to say is that if i use the throttle pinout to send signal and power to the receveir the receiver doesn´t work. If I power the receiver using the pinout from the ESC/BEC for exempel D12 the receiver starts and everythign is ok ... I don´t understand why i can´t get it to work the same way as you mentioned in your video.
+Painless360 Thanks !
Just a small question, I resolve my power receiver issue by fetching power from the D12 pinout so far so good.
I calibrate and made the confirguration to my ESC (via transmitter), balance my props, correct rotation and CW CCW prop in the correct motor (QUAD X).
Now when i test it the quad doesn´t have enought power to lift.
If i try only one engine/ESC directly connected to receiver (NO CIRUS) I get a lot of power from engine but when i connect the receiver and the Engine/ESC to the CRIUS I don´t get that much power as directly to the receiver.
I´m having "juice" problems. It can´t be a battery problem (Lipo 3S 1100mah 35-50C) otherwise it should perform the same with or without CRIUS.
Is it some confirguration that i´m missing? Is it something worn with the CRIUS board that are giving me the same power problem with the receiver and now with the ESC?
What do you think it can be ?
thank you very much.
It could be lots, I'd check that you only have the most basic flight modes set when trying to take off for the first time. Best of luck..
I dont knoe if its cuz of the receiver, but it really just doesnt arm, could it be the multiwii that isnt programmed right?
Radu Christian Possibly or the throttle channel is reversed.. what troubleshooting have you done so far?
Great video & thumbs up. Cheers from sunny Sint Maarten
Hi. Thanks for all your video. I just finished build my 1st quad. My 1st flight was not smooth at all. It goes flip at one side as if 1 or 2 of the motors is not power enough to take off. If it flys it will drift at a side quite fast and flip. Can you help me how to solve this? Hope to fly smoothly before i breaks the props :((
My gear - multiwii v2.5 + flysky fs-t6
Hi, first thing to check is that you have the motors connected on the right way and that none of your props are installed upside down...
Hope this helps..
Hi, thanks for your reply. I've checked all my motors, they are all connected correctly and the props are installed as they supposed to be. I manage to fly it at about 2 feets and the moment its start to fly, its drift to a side. Will try it again on a grass so that they won't crash badly. Earlier i was trying on a hard floor.
Hi Emo, if that is all ok then recheck that the artificial horizon in the MultiWiiConf responds as you'd expect and reset the accelerometers.. Hope it helps.
When i take the multiwii out of the ftdi.. And leave just the ftdi and try to upload it to it... It says the same thing...that it canr upload. i have the blue deek-robot for the ftdi do you know something about them?
I only use the FTDI Basic I show in the video - works great. Go back to the supplier and ask for support.
Best of luck..
The problem is that it doesnt take any command on the sheet you sent me, no command is transmitted :( the multiwii is beebing and the receiver is steady, when i take th motor apart and plug them into the reveiver on the trottle they all work.. So that means the problem is the multiwii??
Sounds like you've missed something basic. I would connect back to the board using the FTDI connector and reset the MAG and CCC using MultiWiiConf and then try again.
If that fails then re-flash the board..
I can't seem to get my hex to arm even after I load the software on the board. Someone said I may need a boot loader? Sorry, a bit off topic but I have the same board and don't know if I need that.
Hi Mark, if you have successfully downloaded the software to the board (and can see it using MultiWiiConf) then the bootloader isn't needed as the board is configured.Check out my video about troubleshooting arming called 'Multiwii Arming' (@watch?v=lc4ECi6JYX4&list=PLYsWjANuAm4qSqszQR6qIisiwk5r-_nMk&index=6) that may help.Good luck with the problem.
I did exactly the same thing and it says always problem uploading the board...
I followed your procedure but when I plug in the power to my quad copter my esc's beep constantly and even when I arm the board it continues and I have no throttle.
What does it show when you look at the board through MultiWiiConf? What ESC(s) are you using?
I want to thank you for sharing this information with us.
Good flights and excellent landings.
Only happiness :) :) :)
Awesome video, I have the 2.5 Crius board and the one thing I have yet to figure out is the AUX channels. When I have multiwiiconf running and then I flip my Flap/Gyro switch, I see nothing in multiwiiconf, no values at all ... I have an OrangeRX T-Six and already found another video for setting up the Flap switch and for the transmitter monitor the switch movements in real time, which work on the transmitter, I see arrows moving. On the Crius board, I have AUX1 connected from myR615X receiver (signal cable) to the Crius board on the AUX1 pinout ... Googled all around the world and still can't find any extra information at all as was wondering, with all of your quad expertise, whether you have any ideas on this problem sir! Any help would be massively appreciated! Keep up the good work!
The easiest way to check is to plug a servo into the connection on the Rx and check it moves as you change the values on the channel. I've found that I had to plug the aux connection from the Multiwii into the AUX1 port on the Rx to pick up the changes in the channel values from the mode switch (I use a Heli setup).
Not sure if that helps. Pictures and videos of how you have it setup would help..
Hi Painless360, thanks for the advice :) I had to flash the Crius board v2.5 with the Crius v2.0 selected in the config.h file as selecting the CRIUS_SE (As recommended in the v2.5 manual) did not work, I suddenly had no sensors! I then configured the ESCs to correct wrong erratic motor speeds. I think the board just needed re-flashing. I then configured the ACC followed by MAG in Multiwiiconf. Now I just have a massive drifting problem and trying to guess the PID (start with 0 and work my way up using the holding over head method) as there's not really many examples for a good PID out there for an X525 ... The amount of trim I need to put on the transmitter is insane at the moment. I ordered another FC just incase the FC still has some issue ...
I'll get some pictures together though, just in case you notice something massively wrong in the setup ... The Quad has been configured as ACRO (plane) on my OrangeRX T-SIX transmitter ... By recommendation of other RCForum posts that I have read ...
+Painless360 if I have set up my quad and done all the connections and programming will the quad fly or do I have to do anything more?
+vansh gupta Normally, I'd test that I can arm the board, run the motors (all with the props off) and that they turn the right way. Once I'm happy then I'll try a quick test hover over grass. Best of luck!
+Painless360 after I have tested the motors it did not fly when I took it out
+Painless360 also I have 2200 kv motors and 5000mah battery
+Painless360 pls help me
+Painless360 Ihave a fly sky T6 controller
In one of your videos you mentioned how to apply low pass filter in multiwii i.e 42 khz ... i just wanna ask that how should i apply same filter on my quadcopter? I only changed FC from multiwii to apm. In multiwii i got stable flight but now having takeof issues in apm. Thanks
LPF filters are there when you can't get rid of excessive vibration on the model. Id' look at that first, maybe an anti-vibration mount for the APM?
Painless360 i putted my apm on 3mm foam and it is stable in loiter mode. Perhaps when i push my quad to any other side it still comes back to its location. I think its stable now isn't it? Btw love your all of the videos :) happy flying
+Mukarram khalil you too! :)
How many channels receiver is needed for quadcopter ? Thank you for answer
TheManneidomu Minimum of 5 - see open-txu.org/home/special-interests/multirotor/intro-to-opentx-and-multirotors/
Happy flying!
thank you ! :)
Hello, I brought the HKTR-6a, I really do not know which channel is Throttle or Aileron？my receiver shows CH1-CH6,which I have no idea. Please help me, thanks
Hi, it's never helpful when the manufacturer doesn't mark the receiver! The detail you are after looks like it is in the files section at the bottom of this page - www.hobbyking.com/hobbyking/store/__9042__Hobby_King_2_4Ghz_6Ch_Tx_Rx_V2_Mode_2_.html
Look for the file called 'Channels' you can always check this when you first connect the Multiwii to the MultiWiiConf interface. Check that the channel you are moving is the one changing on the display. Bets of luck with the build.
Mine was the same way, I used my oscilloscope and probed everything out, and figured out what channel was what. You could also connect the esc directly to the fifteen channels and then plug in the LiPo and see which gimbal controls the motor. No need to arm in the direct receiver-to-ESC connection.
Hi! I connect my multiwii to my quadcopter but it doesn't do anything. It is connected with ftdi to pc and I have open that configuration program. In there I can see when I move stick on my controller and everything is working, only propellers doesn't spin even when I am off from config program. When I turn on quadcopter there is only green light. when I move it than is also blue. I move my stick to unarm it nut nothing happens. Motors just don't want to turn :/// please help :/
See the next video in the series..
I have seen it. it not helping :/
Hard to help with the very limited detail you're giving me. Happy to help but please watch th-cam.com/video/olIqTiSJHIY/w-d-xo.html and come back to me with more detail of what you've tried..
is it possible to make an RC plane without using multiwii but just receiver and transmitter....
+Akshay Das M.K it sure is! See the videos in the fixed wing series. Happy flying!
Could I connect gimbal motors directly to the Multiwii SE board? Thanks!!
No. You need an esc to drive them.
+Painless360
Then how about the sensor that should set up on the gimbal to detect the axis of the gimbal. That sensor comes with gimbal controller. But without sensor how would I track the position of the gimbal with only using multiwii?

I guess I need some more expert help here..
My quad was sitting around for about a week and now when I try to fly it it it won't take off.
The strange thing is that Yaw, Pitch and Roll are responsive but Throttle only gives out a little more speed. The quad stays on the ground. I re-flashed the board, re-calibrated the ESCs with the software and the Tx, tried out a "clean" new MultiWii code, even switched the board, but nothing helped.
I looked at the GUI and all the signals to the ESCs are normal.
Any ideas?
Do the ESCs work normally when pugged directly into the throttle channel of the Rx?
If you can see the throttle rise in the code then the MWC and Tx should be fine. Obvious question but I've got to ask - anything changed on the bird since it flew normally last time?
That was what I thought as well.
Nothing changed since yesterday.. Yesterday was good, but today no fly :/ .
ESCs work normally when directly connected to Rx.
If that works then I could be a bad connection in the power system/battery connection. If all four motors have the same problem then I'd check the battery, connector and connection to the power distribution board..
I did connect some led strips on to the PDB, I'll remove them and try again, great idea!
Well it didn't change anything unfortunately.
Hi, Tell me please? whats wrong with my board. Blue led flashing all the time . Rewriting new firmware did not help. Maybe i burn it when connect throttle from receiver in wrong way. Thanks!
Hi Саша, Does the board connect to MultiWiiConf once it's flashed? The LED will stay flashing for a number of reasons but one of the simplest is that the accelerometer calibration hasn't been done/the board isn't level. Try that.
Hope it helps. Happy flying!
Painless360 No, It is not connected to MWC. Just plug the battery and it start flashing. And I can not activate it. Try to calbrate acc.Thanks!
So you get an error when you try and flash the firmware using the software then? See Crius SE V2.0 MultiWii Board (MWB) Overview and Setup for the details..
Painless360 Yes i use this instructions from beginning and everything was OK. I flashed new firmware - 2.2 2.3, but board did not work properly. I decided flash board with your firmware 2.1 again (with this firmware board work properly). Flashing was OK, but board did not work.
So, to be clear. You have calibrated the compass and accelerometers using MultiWiiConf? If you have then make sure the board is flat when powered on. Failing that, schedule a Helpout time and we can take a look.
Very helpful, thank you for posting.
i have a question, why do we use silicon cables for multirotors instead of copper wires?
+Friederrich Eggeling For the insulator?
+Painless360
i mean normal wires like the ones for wall plugs
You'll find that those are rated for mains voltage and not designed to be flexible. The cables used in RC typically need to be very flexible and work across a huge varying temperature range. That's why silicone insulation can be better sometime.. Have a google, there's loads out there on it.. Best of luck!
+Painless360
ok thanks
ho do I know which receiver channel is specified to a particular motor?
+Akshay Das M.K all in those videos.. ;)
Btw i have an ar500 so it is already 5 channels, but i have gear and ail again besides my thro, ail, elev, rud, where would the aux plug in to?
The gear channel. That will allow you to have two settings for the modes on the Multiwii.
this was a great video it helped me doing this the first time a million thanks
+bruno gallizzi Glad it helped. Happy flying!
Thank you very much!!! U saved my hairs...
Hie painless 360
M having problems with my multiwii se v2.5. When i connect it with ftdi (no other connections) it works fine but as soon as i connect receiver n motors it start giving weak green light n no blue light i tried to give 5 v supply by power supply to power but insted of battry eliminating ckt of esc but facing same problem
When i remove receiver n escs then again it works fine gives signal in config
Tell me how to overcome it.. Plz help
Happy to help but please watch th-cam.com/video/olIqTiSJHIY/w-d-xo.html and come back to me with more detail of what you've tried..
Painless360
I observe that only when i plug receiver +5v and ground pin this think happen so i took +v and ground from motors +v and groud bus nw its working fine i can observe all singals from tx in software on pc but i observed my singals its varying from low to high ( all 4 signals) but when i tried to arm it its not happening
Signal lev at zero throttle is not exactly 1000 but 1004-10 its not exactly zero n in full range it's not exactly 2000 but 2005-10 so could that be resason to not arm?
+Atul kamble if you're LEDs are not in coming in properly then that suggests a power problem. See the MultiWii series on the channel for all of the basics. Best of luck!
If I install the gps that goes with this board and want to add an OSD does the OSD also need it's own gps module?
Most OSDs come with an integral GPS already so it depends on the one you are going to use - there are lots to choose from.
I have videos for the EzOSD that is excellent..
Painless360 what do you mean integrated? I have been looking at some OSDs on Hobby King and most of them do come with a GPS module that comes with it but it is not integrated in the OSD board itself, it connects to the OSD board. So is that what you mean when you said integrated? So my questions is. Do I need the GPS for the control board to use features like altitude hold and return to home and another GPS module compatible with the OSD board? All I want the OSD is just so that I can get basic info like battery, altitude, and coordinates of quadcopter location in case if I lose it. I will be getting Multiwii and Megapirate AIO Flight Controller w/FTDI (ATmega 2560) V2.0 for my control board on my quadcopter. Thanks
Sorry I've not used the ones you mention.
I use the ones that come with the GPS as part of the device - all ready to go. I'm very impressed with the ImmersionRC OSD devices - you get what you pay for and the EzOSD has already saved me £400 by allowing me to walk directly to a downed quad (crash-landed in the middle of a planted field). I'd have had no chance if I hadn't been using it with the iPhone app to track location in real time.
For the ones you describe I would guess you need two GPS receivers - one for each. Unless you can split the signal from one unit and get both the MWC and OSD to expect the same baud rate and protocol from the GPS Rx. If you figure it out I'd like to know how you got it all working with one.
Good luck, happy flying..
Painless360 ok thank you
Hello Mr Painless, I have to tell you how much help you are giving me in setting this board up. I am only as far as plugging in motors, esc's and board. prier to that I was able to separately run the motors for the right direction.
Q#1 My receiver has1-6 +battery symbols only. yours has names for what there for. I did try to just run up with my numbers. nothing seems to work at all. the board lights do go on initial plug in, But then nothing happens? No response from joy sticks. So I can tell you this.
#1 The remote is bound with receiver
#2 The connecters are joined with board and (numbered?) receiver.
#3 The connecters are joined with esc's and board.
Can you tell me what I am missing?
Thanks in advance
Kazz
P.S. Does the board need to be powered separately?
The numbers on the receiver will correspond to the channels - you need to read the documentation that came with the radio/receiver to see which of the numbers is the throttle, rudder etc.
Best of luck.
Painless360 Thanks, No sign of Documentation? Hmmm?
But I can tell you that I have spent all day and night watching you video's till I discovered that I've been watching all but 1, The very 1st one of your about FTDi adapter. Dummy me! So I went ahead and ordered 1 FTD. Please,Please tell me that that is highly possibly my problem? and that My Multiwii board has to be programed as you had mentioned on your number 1 video which I clearly missed all day long.
THx Kazz.
The Multiwii will not have any firmware on it so you will need to start there. I suggest you watch th-cam.com/video/Zm8z4RLkFGU/w-d-xo.html and go from there..
Painless360 Please help Mr. Painless, I did order and received and that device you plug into the board and computer and followed trough your 1st vid. (all good) I now have all the plugs connected according to your 2nd vid. And at the end of that vid, You mention to go ahead and plug it back into the computer to program it again? Could you tell me what I am programing? I cant find a Vid of yours about that part. P.S. I am not even getting the throttle to run like you did after you hooked up your receiver to your board? Thank you so much. Kazz.
If the board has already been programmed then you don't need to do that BUT you do need to check the channels are all working, the MAG and ACC are calibrated and you can see the board moving in the right way in MultiWiiConf.
Happy flying!
Please help me, I have no respont remote controller to my multiwii board it's nothing happen, and i have flysky i6 rc... Please
Happy to help but please watch th-cam.com/video/olIqTiSJHIY/w-d-xo.html and come back to me with more detail of what you've tried..
i was tried connecting multiwii se v2.5 to multiwii config x62 bit and it's working, but when i try to connecting again and i plug receiver fs-i6 flysky it's not working or the blue light of multiwii stop blink the nothing respont in throttle or all channel when i'm turn on the remote control flysky then when i turn off the rc is comeback to normal and blue light comeback to blink again, help mi please
Perfect explication !! Danks
Gweniman you are very welcome, thanks for the feedback!
Wow! Thank you so much.
hi, I'm using flysky fs i6 radio and multiwii 2.6 . when i directly run the motor with receiver, it will run. but when i plug it in multiwii then motor wont work.
can u please help me with it
+Ashish Thomas have you armed the board? See the later videos in the series..
Painless360 yes i did.
i have watched all the video of your series and everything was perfect. when i plug all the wires of motor and receiver on the board and try to move throttle or any key. it doesnt move. I'm not able to understand where is the problem
+Ashish Thomas a video showing the problem and a full list of the troubleshooting you e already tried would be helpful..
If acc isnt calibrated can i do that without connecting to computer?
Yes - see api.ning.com/files/4*5ByqO6p6fl1A-5uXSbAitAUuH5VGA*gezLVGDeZoWMvIacvHiGZ0VLlpK17Wb1RQRWiU3vRjX6esWFKwvvK1fzDjTgZXe-/Multiwii2.2stickconfigurationmode1.JPG
I tested my receiver to my transmitter and it works fine but when I wired the receiver into my MW board I get no responses. Am I to do something in the config.h settings? I am using a dragon link receiver.
That should all be sorted in the config.h already. Have you checked that you can see a servo move when it's plugged directly into the channels on the Rx (troubleshoot without the MWC to start with)?
If so then use the MultiwiiConf program to see if you can see the values moving on the screen as you move the sticks.
Painless360 I successfully binded my transmitter to my receiver (Dragonlink) then I connected a servo to my receiver and it works. When I connect my receiver to my MW board, I get no responses, even in the MWGUI tool. I move my sticks but nothing seems to happen. I am using the Turnigy Open9x.
BUT when i move my throttle i do not get any motors to spin
You are arming the board? (Usually throttle. Stick to the bottom right)?
In order to 'arm' the board as you describe. What needs to be set in config.h ??
when I take a voltage measurement at the FC pins to the ESC's, when the throttle is full I get minus 5 volts and when I put the throttle off I get plus five volts. This does not sound right. This is across the RED and BLACK pins.
Ive tried everything in the config.h i dono whats going on...
usefull vid, thank you
same method also working on multiwii328p?
Hi Luca, each board is slightly different but the principles are the same.
Happy flying!
Painless360 receiver pins are trh
ol\pi\yaw the escs connections are D11 D3 exc
which pin for the battery?
Hope to an happy flying, this is my first quad, diy fan, includes a lot of questions
Thanks in advance
The power for the board (+5v) is usually supplied via the red cable that comes as part of the servo lead from the ESCs that power the motors. You may find this video useful - th-cam.com/video/-gOupB8xnlM/w-d-xo.html
Thank you, Thank you, THANK YOU!
You are very welcome!! :)
great vids and instructions. i was wondering how tohook up a spektrum ar 770 with srxl. any help would be appreciated
+natet4 Not sure - never used one. Follow the wiring for the PWM connections I'd expect.. Best of luck.
+Painless360 where to put the GPS?
+Painless360 I have a fly sky receiver so it has ch1-6 written instead so where to put the wires
Use the manual or the screen on the radio to figure out what channel corresponds to which number on the Rx.. Best of luck!
can you do a quick over view of the MultiWii 328p ? thx
***** please do a video on this
+michael lee i agree!
Hi,
I saw you videos and they helped me a lot!!
So first thank you for making them.
I have some problems with my Multiwii SE V2.5 quad and I thought you might be able to help me solve them.
When I try to power up the motors, one ESC stays "off". It only engages at high speed demand.
After I checked I found out that the problem is in the board pin D11 output, as all the motors and ESCs are fine.
How can I solve that problem? Maybe a software malfunction? Can I control the motor using other pins?
Thanks!!
yoraish
How do you know that pin 11 is the issue? Have you swapped two of the ESCs over and the problem stayed with the one plugged into D11?
If that is the case then check for poor solder connections on the D11 connector, re-flash the board with the software and if that doesn't work then clear the EEPROM and re-flash the board. If all that fails then the board may be kaput.
If you swap the two ESCs as above and the problem stays with the ESC that was plugged into D11 then recalibrate the throttle range on that ESC and see if that helps..
Good luck!
Painless360 Exactly.
One more thing, I can't flash the board :(
I get : avrdude: stk500_recv(): programmer is not responding.
So no clearing the eepro..
I'll check the connections and let you know how it went!
Thank you very much!
yoraish
No luck :/
I guess I'll have to order a new board.
Bad luck. :( I hope the new one behaves itself for you.
Please provide a correct tutorial video for connecting multiwii with a ten channel flysky reciever. We couldn't able to connect it with the videos that you have provided... So please provide the tutorial as quick as possible..
I’ve not touched MultiWii for years so these videos in the playlist are all you’re going to get here.. best of luck!
hiii which type of receiver is specified here...?
Any that outputs PWM will work the same.. Best of luck..
sir receiver is compulsory???
Vipin nair no man
He’s bluffing around
My throttle doesnr work in my gui :/
My green loght isnt on... :/
Hello bro,
I am making a quadcopter using the following parts
1)hextronik nanowii V01 from HK site
2)multistar motor type 2213 935KV
3)10*45 propeller
4)3 cell 3000mAh tunigy battery
5)turnigy plush 30Amps*2 for two motors and 25Amps*2 for the other motors
6)Flysky controller model FS-CT6B.
So far I have fully assembled my quad all the motor direction and all connections are correct.I used multiwii to program my nanowii controller,so i have set as #define MINTHROTTLE 1150 and #define MAXTHROTTLE 2000 also i calibrated my ESC initially using the #define ESC_CALIB_CANNOT_FLY command in the config.h of the multiwii.ino,but I am facing a problem.
After I arm the motors and star to raise my throttler one of my motors(rear-right) is staying constant at 1150 for a while while the other three motors raise up.After sometime the fourth motor(rear-right) also increase and at full throttle three motors are running at 1960rpm while the fourth motor(rear right motor) runs at 1660rpm(as seen from the multiwii GUI). Even during the flight it has terrible problems during take off in fact it is not taking off since three motors are at a higher throttle it tumbles over rapidly. Please Help..
First of all using different ESCs are not a great idea. You ideally need to use the same ESC with identical firmware on each of the arms.
Secondly, calibrate each of the ESCs separately - I've had mixed results using the 'inbuilt' ESC calibration routines on some controllers. See th-cam.com/video/OOplk52R4no/w-d-xo.html on how to do it.
Finally, I will delete all the other identical comments on the other videos. No need to post a question three times.
Good luck with the problem. Happy flying!
Thank you for your advice ... Sorry I had to do it because this is my college project and I am planning to make it autonomous. But just flying it manually is so strenuous and I had limited time so had paste the same question :( to get a quick response. didn't knew all three videos were yours :( sorry.
will try the method you mentioned and will let you know.
Painless360 I followed your other tutorial on how to calibrate the escs separately and it helped in one way that when I used the auto calibration it required me to increase the throttle a bit before the escs start and power the motor but now just as soon as I start to increase the throttle the motor starts and the motor reaches the highest speed, But that didn't solve the problem.
here is my observation .
1)I disconnected all the escs from the board (just to check what the output is my board giving out when the quad is in flat position, anyways connecting the ecss is not changing any value the controller outputs).
2)connected my controller to my computer and all the receiver connections are connected on the board.
3)So when I increase the throttle on my controller I observed in the multiwii GUI that the output from the board is not increasing the same and the problem is not solved and it is just as stated before.
"After I arm the motors and star to raise my throttler one of my motors(rear-right) is staying constant at 1150 for a while while the other three motors raise up.After sometime the fourth motor(rear-right) also increase and at full throttle three motors are running at 1960rpm while the fourth motor(rear right motor) runs at 1660rpm(as seen from the multiwii GUI). Even during the flight it has terrible problems during take off in fact it is not taking off since three motors are at a higher throttle it tumbles over rapidly. Please Help.."
4)Also I saw that changing the YAW calibration on the controller by sliding makes the controller output go crazy i.e. now instead of one motor now two motors are not increasing for a while.
5)The same goes for other calibrations on the controller so I suspect that the problem is with the controller configuration and not the board . Also I am not sure if the using the two different types of ratings esc is the real problem (if it is the real problem please let me know). So do you have any tutorials on calibrating the controller?
This is normal if you are on the bench and not actually flying. Have you now tried a real hover?
Painless360 yup I tried real hover and just as I increase the throttle three motors run faster I suppose because every time it topples in the same arm damaging the blade of that particular motor bit by bit.
In the gui the cycle time and i2c error are going crazy :/
i2c errors are usually hardware or wiring related. I get them here when I enable the GPS pieces and forget to plug the i2c board in.
Best of luck with it.
hello again... i really need instruction on how to connect the raspberry pi 0 to the multiwii and configure it :)) please man make a video...

I dont have a ftdi thats the problem so at least i know its the multiwii
You need to get yourself an FTDI Basic adapter if you are running a board without a USB socket - you can't setup, configure or troubleshoot a Multiwii based craft without being able to look at it using the PC.
