Probably, this was my the longest running project that I finished (not counting abandoned ones) since I’ve started it around September 2016, right after I got a 3D printer. There was always something else to do. But finally, this thing is done!
But first things first. What is dualcopter? How it is designed? It’s a kind of multirotor drone with two motors and two servos. In my case, motors and propellers are coaxial and provide thrust and yaw control, while servos and control surfaces are responsible for roll and pitch control. In theory, should work like a charm. Practice is like always a little different…
Problems I’ve found:
– almost no control during takeoff
– no control during descending
– you tilt it too much, you loos stability
– second, bottom propeller adds very little to the thrust
– and few minors
But it flies! Crappy but flies. And it even survived one crash. Dualcopter did not survived the second crash but that was expected. 3D printed PLA does not last long.
Technicalities:
– Motors: Multistar 2213 935KV
– Propellers: APM 1045 MR
– ESC: Afro 20A
– Flight controller: SP Racing F3 running INAV 2.0 with a custom mixer
– RC: iRangeX IRX-IR8M with FrSky D8 receiver
Ah, I will be designing a smaller 3D printed dualcopter. I’m in a process of designing this thing right now. This time with 5-inch propellers and multirotor parts. Maybe this one will be flying better?
That was interesting and funny to watch as well
tape a wing and a tail onto it?… :-p VTOL
Try a BiCopter ……Mine……….
and one that flips not mine……
need one in between with iNav
I would love to have the possibility to make a VTOL with Inav… I hate to throw a wing in the air
It is this design of a “DualCopter” which creates problems! Once one installs the 2 motors on the ends of one single arm and move them around the axis of this arm by 2 (fast digital) servos, then thrust of the motors will add on and both motors wont influence each other. And… the dual copter will fly….
Great stuff Pawel. Keep breaking things so I don’t have to!
I love it .life is for fun
Why not a further distance between props and with CPP. Use the Tricopter servo control swing arm thing.
why not 2 motors and servos strering motor in place of stering surfefaces
