"i dont have any flux and i dont care"??! Dude im sorry for doing the exact thing you said but...flux is EXTREMELY helpful in some situations. Also great video, thank you so much!
I didn't use flux in any of my builds and never struggled for any of my solders
@@Komet_fpvmaybe your solder wire has flux in if from the factory. Or the mix it’s made from is easier than most to solder with. But generally speaking, trying to solder without can be very frustrating, sometimes solder won’t even melt until flux is added.
@@John_Doe_6996 yeah I Know that's why
The pointy magnetic things that came with your soldering plate/extra hands, are used to hold a pcb. You can put 4 of them in a square and hold your ESC or FC through the mounting holes. Makes soldering a PCB a little easier sometimes
Nice build! Looks solid.
If you're looking for a longer ELRS antenna check out the Foxeer ELRS antenna it comes in a 150mm/ 6in version. Used it on my last 7" build and it works great.
I will be doing a 7in build an this video is a great help.
Sound pretty notch! 10/10 fpv sound its Liken To akrapovic exhaust ❤
nice build!
Thanks man. 🤘
Nice build. One tip, I’d recommend putting heat shrink in the leads for the capacitor. I mounted mine the same way as you did and it shorted out on the frame.
Hey Thanks. Ill check that out, definitely don't want a short.
The Immortal T antenna will work for ELRS, but you might not have the same performance because crossfire is 915mhz and ELRS is 2.4ghz, at least that was what I was told by some ELRS guy, so I use the TBS Tracer antennas, because Tracer is 2.4GhZ.
I was worried about that and thought the same thing. But so far in my testing the link has been solid out to 4 miles (will post that video soon). During my turn around at 4 miles I had a micro failsafe flash bad rx or rx loss but didn't seem to last long enough for stage 1 or 2. The drone kept moving fine. other than that I haven't had any issues thankfully.
@@andrewmedia3568 DO NOT use the immortal T with your 2.4 elrs receiver! You are slowly burning out the telemetry transmitter on the receiver! They are pretty strong, up to around 100mW and that is slowly burning it.
paused the video to look for this comment. defo need to get the correct 2.4 antenna!
@@djSpinege Nah the CRSF Antennas are working perfectly 🫡 😁.
they are not tuned to 2.4 ... far from perfect. just trying to help ... @@andrewmedia3568
Awesome man.
Great video, I would like to see more.😀
Thanks !
Nice build man.
Thank you. 🤘
You the man! I just built my 7 inch and I enjoyed this build video. Great info and also great angles to see the work and process. Going to be putting gps on mine so I can rip in Madeira here in a few months 🤜🏼
Thank you I appreciate. Good luck with your flights 🤘
I will built again my rekon 7 by myself, because I already have very detail how to do it, THANKS alot for your video it is very inspired me ❤️
No problem! Happy I can help.
I appreciate the reply back I'm going to be running a 2806.5 motor probably 1300 kv... I love the way bigger quads fly!!
Nice, that setup will work well. Good luck with the build! 🤘
Thank you
I dont have a drone but I saw a guy that set this rescue stuff in the software many times, he took the computer to the field to keep change. That shut all the way up is that min rescue alt. NICE VIDEO
Thanks! yeah I have changed some setting and its working great now.
Nice job
Thank you 😁
Use tbs flux pen or syringe, 380° add solder and it will melt your grnd mess silky shiny smooth
Well done
Thank you for sharing
For now I'm using iflight
I know it's not good...
One day
Well done again
The frame comes with braces but not hardware to take into account the added carbon? What a jip lol Solid build video. Good luck on your future flights friend!
thanks!
Dream 😊
43:05 Duuuuuude.... I had my Fingers messed up from that kind of Start. Just dont do it, you never know if the gyro sends out corrupted data while arming. We had multiple Death rolls right after arming, due to Gyro shenanigangs, and since have established a 10m safe zone fpr starting. We had to learn the hard way through multiple mild and 2 really severe cuts.
😅Dang ok good info Thanks.
@@andrewmedia3568 As RC heli pilot, that start and landing gave me chills. I heard stories ending in deaths, so really do not do that please...
@@jointercz I hear you, and appreciate the heads up. 🤘
Totally don't do what you did, or you'll miss having 10 fingers sooner or later
Yep what they said
Put the needle nose pliers in the tool box and get yourself some flush side cutters to make building easier
🤣 yeah I need a few tools.
I just used ELRS915. And also using crossfire t-antenna.
Im using crsf immortal T with 2.4ghz 🤣. It works though.
@andrewmedia3568 I mean I run my vrx with no antennas in my house .. it work to a point. I'm really really curious the range you'd get at 1w. I seen them go 100km on elrs24 and didn't even lose telemetry till 80km . So curious if you could still make it like 15km something reasonable
For long range you should change out the reciever antennas to 2.4ghz the one you have on is for 915mhz
Yes I was worried about that but so far its worked great out to 4 miles 🤷♂
the stock ELRS antenna would give you a stronger signal than a wrongly tuned antenna. so far you got lucky! Happy flying@@andrewmedia3568
@@andrewmedia3568 Why bother with a long range control link if you're going to handicap it by using the wrong antennas and detune your radio? You can get 2.4Ghz antennas with longer leads. Use them.
@@Invid72 I have 0 range issues. I’m still using the same RX and antenna today, it works great. I’ve got some videos of me flying in the mountains if you wanna see😁👍. Even flew behind some trees at the top and never had any problems. Lots of people saying it won’t work but it seems to work extremely well.
Nice build, I’m using the same fc/esc. How did you connect the 03 up? The wiring harness from the 03 is not the right one for plug and play. The wires I got from the fc doesn’t fit the back of the 03. thanks
Yeah t-motor has a weird plug on this fc. I had to special order one from rotor riot.

Thanks for the video, did you make any changes to the listing of this equipment you used? any new configuration? I want to build a long range 7 racer, with air 03 dji! hug
I have since swapped the frame because I crashed and broke the frame and couldn't get a new one in time. I made a video of swapping all the parts to the new frame and I think the new frame is better than this one. thats the only changes if made. th-cam.com/video/xZk0Hpctw9I/w-d-xo.htmlsi=iT2NF_xEtqYqw-Pu
Please invest in a real soldering iron with temp control. It'll make life much easier. 😢. Nice build and great video!
🤣 yeah probably a good idea, thank you 🤘
Why are you using crossfire antennas on elrs 2.4ghz? Otherwise it is a great build! If it has micro failsafes at 4miles, it is not good. My 250mw elrs goes out to at least 8 miles without any issue.
well all the 2.4 antennas are very short, maybe the micro failsafe is from my antenna placement. ill never need to go past about 5 miles otherwise i wont make it back, cant carry enough battery. you must be referring to a fixed wing at 8 miles out.
does longer VTX antenna give you longer video range compared to the standard stock antenna that comes with the o3?
Yes and no, Technically different antennas have higher or lower gain, higher gain being better for long range. But in my experience thats not what gets you better video range. What the longer antenna does do for range is insures that they wont get blocked by the quads frame or battery when flying far away and making turns. That way the antenna always has direct "line of sight" back to the goggles.
I wish my rekon7 had more room for longer battery. I modded my rekon7 and now im thinking of bigger motors. Was looking at 2808 or 2809 but i want lower kV maybe 1100kV
2808 works well on mine. I’m at 1500 kv 6s. But 1100 kv would work too.
@andrewmedia3568 yea I'm just going max flight time. I'm patient I don't need to go fast. Just slower if high winds. Also I'm not running 7" props anymore. Meant to post video on it years ago. Never did. I'll do it this year 🤣
Hi, if I'm using Dji Goggles WITH a dji controller together with a dji 03 air unit.. do I still need to purchase a receiver like the crossfire nano with mortal T antennas ? Thanks for your help.
No not if you are using the DJI controller. But the O3 only works with the DJI remote 2 (the Grey controller).
hey i was wondering if i buy a iflight Evoque with 03 air unit to use it with my dji controller 2 can i get it with the tbs receiver just for when i get a tbs module at a later date? like will it still be able to bind to my controller 2 when i get it with tbs as easy as i would with the controller 2? thank you :)
To quickly answer your question yes you can. That bing said, if you buy the TBS version once you get the drone you will need to hook up the O3 using all 6 wires from the O3 plug. that will be RX, TX, 10v/vBat, G, SBUS and signal/ground. The extra 2 wires SBUS and signal/ground are really what is needed to use the DJI controller. The TBS version might come without those wires hooked up or the wires missing from the plug. so you might want to buy an extra O3 plug that has all 6 wires. Of course you will need to change Betaflight settings for the DJI controller to work and then again when you switch to TBS. There are tons of videos explaining how to wire the O3 for using the controller 2 and how to set up in Betaflight.
@@andrewmedia3568 thank you
I'm doing a 7" build and I have a speedybee f7v3 50 amp stack laying around so do you think 50 amp is enough for a esc??
Yes definitely. Remember that’s 50 amps per motor. So 200amps total. And depending on motor kv and battery voltage you won’t even come close to hitting that max. Most batteries can’t supply that for more than 1/2 of a second and then voltage sags. 50 amp esc is plenty if your motor kv and battery voltage are correct. You can use the same motor kv I did 1500kv and 6s or look at other 7” long range bnf, what motors they use and what input voltage they say to use. Hope this makes sense and helps.
sick build broh, You know the thing that sucks about long range is that you can lose your drone and these builds aren't cheap.
Thanks ! yeah they are pretty expensive, especially digital setups 😅
Hey brother I love the build and video. Keep up the good work. Do you sell or build to order?
thanks, I have only built for friends but I could build a quad for whoever. what did you have in mind?
@@andrewmedia3568 I like something like what you built. I can control the speed and possibly take video.
@@dwaynewalker5035 if you don't want to build the dji mavics are solid drones and have great cameras.
@@andrewmedia3568 I just wanted something more personally made for me but if I have to go that route I was thinking about EXO cinemaster 2.
Doesn't the o3 have a reciever on it? If i just want to use dji goggles,controller and air unit, would i still need to attach a receiver, also does your build provide longer range than the stock dji ecosystem
Yes the DJI O3 has its own internal receiver. you don't need an external receiver if your going to use the DJI controller 2 with the O3. Running ELRS at 1W radio output will give your longer receiver range, video range is the same regardless of your radio
eceiver.
Thank you so much, would you trust the stock dji products with flying around mountains? what is the max range you think you can actually get out of the stock dji products?@@andrewmedia3568
I have a beta flight fpv goggle can I use that for the DJI air unit
No sorry only DJI goggles work with there air units.
Yo bro, just so you know crossfire antennas are 915 and ERS is 2.4 just so you know that will decrease your range in reliability. I did the same exact thing thinking that it would help but my buddies called me out on it and I want to help you.
Oh yeah I'm very aware of the antennas. I have had 50+ people tell me that its impossible to use these antennas and that it wont work. but sometimes you gotta break the rules lol. I have flown 4 miles out with these, multiple mountain flights in the 2-3 mile range and quite a bit of overall flight time, never had an issue. it works great. 🤘
maaan these are LOUD!
Hallo , how is running your frame to vibration ? Do you run lot of filtering ? Do you have any shaking so on ?
stock Beta flight 4.4 or 4.5 should be ok. But I made some minor adjustments to the PIDS. I think the filtering might be stock beta flight. Im using a different frame now. The foxeer mega 7. I posted a video about the frame swap and have some mountain flying videos posted as well. Its all on my channel.
Oke , i do have lot of frame resonance issue with this frame at 78 hz
@@E.Z.F.X. Interesting, I have never messed with Motor frequency on any of my quads. I never felt the need to anyway. Maybe some bardwell videos could help?? or you could email him. Sorry I cant help more with the issue.
Sure thanks for ty help anyway i find many people which have run the same setup without problrm so i should look where is problrm maybe in hardware thank you regards
Can you post here your pids setting ?
you should use a light colour wooden table instead of dark color
Yeah the image is a bit dark. I appreciate the input. 🤙
What kind of flight time can you expect from this do you think?
With the two 6s li-ion 21700 cell packs running together in parallel I get about 15-18 min flights depending on how im flying. total of 8000Mah. if im running it pretty hard about 10-12 minutes.
LONG RANGE HOW KM ?
How much did this cost ?
Not sure the exact amount, but around 700 -800$. could be done much cheaper with a less expensive FC/ESC stack and going analog.
How many minutes you can fly with one battery?
Depends on the battery. Small lipo 4-5 minutes. 2 li-ion packs 10-20 minutes.
Can i have some more info? For a complete build 7"?
@Dshot can i do long range with 2750 motors?
is 2750 the kv of your motors?
Yes they are. I believe they will draw too many amps and will probably damage the battery but wanted to know what you think
@@Matthew-dr1tb that all really depends on what battery voltage your using and the weight of the quad. 2750kv is high speed 4s, too high for 6s. But depending on your drone weight and battery mah you could do medium range. Typically you want a bit lower kv for efficiency when flying long range.
Hey where is Batteryy building vidoe ?)
I never released it sorry. But here is where I learned how to build them, its a great video.
th-cam.com/video/CLyWh9Sc7C0/w-d-xo.html
Hey u have a video abt the li ion pack?
Yes just haven’t finished the edit yet. It will be up soon.
definitely the wrong antenna for ELRS, the Immortal T are wider in length for a reason, they tuned for 915/864, ELRS is narrower because they are tuned for 2.4. You may find it still work, but definitely not the right choice cause you're maxing out the receiver's output power and it will slowly burning it.
Is the receiver outputing anything?? isnt the RX just listening to the radio commands? I dont have telemetry enabled.
@@andrewmedia3568 the FC will transmitter telemetry to your raidio through the reciever.
Can you disable it through the radio or BF? I don’t think I have telem on.
@@andrewmedia3568 yes, it's in Betaflight, turn off output telemetry. forgot in which page, I'm sure you can find it.
LONG RABGE HOW KM ?
Ive done 6.5 km
Can I watch your latest LR video?
I tried to click on it, but it said that it was a "private" video.
I'm just another LR quad experimentalist, interested in other's discoveries.
Thanks in advance!
I'm almost to 20KM.
Using TBS CRSF and HD-Zero Freestyle VTX.👍
Unfortunately that video is unavailable now. Sorry I’ll have some other LR videos posted soon.
@@andrewmedia3568
I really appreciate that very much.
I too am learning LR quad flight.
Got some great stuff here and looking forward to surfing "Mt.Olympus", all the way to the glacier! That's a long way too!
😃👍
HEY man did you save money bye doing this
Depends on the parts you buy. But generally yes you save between 200-400$ building your own. Look at the price of an iflight chimera pro 7” they are like 1000$. You could do this same build now for like 6-700$.
thank very much @@andrewmedia3568
never use a ball end Allen key..
I like to be risky 😄
no kidding. that wrong antenna would make my balls sweat. almost fail safe a few times! cant trust RTH to save you from a failed link@@andrewmedia3568
