You either have a lot of vibrations going on or the gyro gain is set too high because those servo's are constantly twitching. I'd also recommend not launching that close to your face, getting hit by those props will cut you up real bad.
Bicopter looks great. Good work! I've built two dualcopters and both servos wobble like yours when the yaw 'P' is set to high. Recommend lowering yaw 'P' to zero and gradually increase until the wobble appears and then back it off a bit. Let us know if this works.
You should use PID controller to reduce vibration, looks like it balanced the bi copter without using PID control and directly from sensor data. Very good design!
Its a really good question.. i will have a go at answering it!!! a lower Kv (I.E 1000Kv) will spin slower and hence have more torque and will spin a bigger propeller. I high Kv like 2200Kv will spin quicker but have less torque so cant handle the big propellers. The Kv number multiplied by the battery voltage gives you the RPM. So for the same battery your 2200Kv will spin at more than twice the speed of the 1000Kv. I hope that helps, i tend to keep it simple and stick with just one motor propeller combination.
Mr.Fid, what if you only had one set of servos set up to adjust the weight of the battery on the bottom and secured the motor to be a solid mount ? It's very cool ! I often dream of building a mansize bicopter like the one from the movie (about the spy kid?).
flight time was about 10 minutes. The frame was made for a small multiwii board, but i am sure you could fit a raspberry pi in there somewhere? the zero (if you can find one) is very small
Very innovative. Do you need both servos? I wonder if part of your oscillations are coming from the two servos fighting each other. You might disable one servo and see if that helps.
+Tom Busey I don't think you could get away with only having one servo as it uses both to control the yaw, one goes one way the other reverse. for forward and back it uses both together in the same direction. (if that makes sense)
Is the vibration from over compensation? (Oh I see someone mention balancing propellers) might be more responsive with higher kv/smaller diameter propellers, easier on torque for the servos too.
Thanks, Making stuff is what i like to do! and i will keep on sharing in the hope that it will inspire the youngsters to build things (and get off there phones!)
+Brandon Piner Its a very good point! I have to be honest out of all the model I have built this one needed the most setting up and tuning and even then its still a work in progress. And I don't think it will ever be as good as a quad / hex or tri!!I changed the servos to high speed ones and if you can believe it, it got worse!
@@aasishkharel the servos are an important part of the control, if the bicopter starts to wonder forwards, thern the servos will tilt the motors back to stop it. and if it starts to spin then one will go forwards and one will go backwards to counteract the spin. my design can't work without servos. the only movement which doesn't require servos is left and right movements where one motor is speeded up and the other slowed so it moves sideways (left and right as you see the picture)
Not well! it really doesn't like wind and you run out of travel quickly! i am sure if you persevered with it you could get it to work very well, but i ran out of time!

Brilliant. Scale it up and it'd make a great personal transport!
that is quite an odd looking machine....very cool!!!
Nice
Mantab. berani eksperimen.
Servonya kewalahan ya?
Whai is the mid position (degree) of servo??

+M Clay I have had a play with this and managed to get it better, but at the time I took the video I was happy to actually get it flying!

Why should not we use 1045 prop on 2200kv motor

I'm building a bicopter can give me a hand?
u r right haha

what is the flight time , also , do you think a raspberry pi can be fitted inside ?

You could probably make this go horizontal and fly like a plane. VTOL. Flies faster and farther but lands in q smaller and more controlled area
Great project, congrats!!
Thanks, it was a good challenge!
DOESNT LOOK DANGEROUS TO HOLD THIS THING NEAR YOUR FACE DURING FLIGHT CONGRATULATIONS FOR STAYING ALIVE
I want a detailed comparison between this type of design, a single swash contra-rotating design, and a double swash dual ended design.
Ha, , , if you invert it, you can cut the grass at the same time
You should add a gyro to help the balance

Reminds me of a manhack from Half Life for some reason.
Pretty cool!
Is the vibration from over compensation? (Oh I see someone mention balancing propellers) might be more responsive with higher kv/smaller diameter propellers, easier on torque for the servos too.
its a control thing! to much proportional gain? it was made loads worse by quicker servos.
mrfid72 I think this video is somewhat old you've probably improved it by now. Anyway great videos. Interesting mix of different topics.
motors are vibrating.....its very dengerious.......!!
Really cool project, keep up the great work your on the right track, Thanks for sharing
Thanks, Making stuff is what i like to do! and i will keep on sharing in the hope that it will inspire the youngsters to build things (and get off there phones!)
Awesome! Just need a custom flight controller because the control is a bit off

You deserve noble prize..
balance your props
In my frame i cant put servo.So can i make it without servo ??
you need the ability for both motors to move. the servos drive the Bicopter forwards and backwards and control yaw.
Cant we drive it forward and backward without servo?
@@aasishkharel not really, unless you have a new design!
You mean it cant fly forward and backward without servo right?
@@aasishkharel the servos are an important part of the control, if the bicopter starts to wonder forwards, thern the servos will tilt the motors back to stop it. and if it starts to spin then one will go forwards and one will go backwards to counteract the spin. my design can't work without servos. the only movement which doesn't require servos is left and right movements where one motor is speeded up and the other slowed so it moves sideways (left and right as you see the picture)
im use motor 1000kv so not enough power to keep my bicopter fly
thats a shame, the only reason i had these motors was because i brought them by mistake!
how does it perform out in the field at higher speeds?
Not well! it really doesn't like wind and you run out of travel quickly! i am sure if you persevered with it you could get it to work very well, but i ran out of time!
sounds
Can you share plans for that i would like to build.

+mrfid72 Thank you.
I would suggest adjusting the PID loop to get rid of the servo jitter
+Soxco how do you do that?
+BadIdeas101 Just google 'pid loop multiwii', there is good advice.
+BadIdeas101 On this Flight control board you can use a Bluetooth connection to a tablet and adjust the parameters PID rates and other bits!
the blade closest to the shed is out of balance, otherwise awesome
+Al Lloyd I crashed it so many times I ran out of blades!
+mrfid72 No worries, i've got a box full of wonky props as well for test flights. lol . nice build. saw it on instructables keep up the great work
Any on board electronic gyro or not?
the multiwii flight control board has the 6050mpu (6 axis gyro/accel)
Why does it shake?
this was an early test, the PID settings needed to be adjusted to stop the shaking.
Where can i get design dimensions

thats really amazing,
I think if you add another motor on the bottom of your design might give more stability
good luck sir
