When it comes to passion rotorcraft, it practically looks like the more rotors, the better. Quadcopters, hexacopters, and octocopters we’ve seen, and there’s almost certainly a dodecacopter buzzing about out there someplace. But what about going the other way? What about a rotorcraft with the least complement of rotors?
And thus we have this unique “flying stick” bicopter. [Paweł Spychalski]’s development reminds us a tiny of a miniature edition of the “Flying Bedstead” that NASA used to teach the Apollo LM pilots to contact down on the Moon, and which [Neil Armstrong] famously ejected from immediately after getting the craft into some of the attitudes this small equipment found alone in. The bicopter is unique thanks to its fuselage of carbon fiber tube, about a meter in length, every single close of which holds a rotor. The rotors rotate counter to each individual other for torque handle, and just about every is mounted to a servo-managed gimbal for thrust vectoring. The regulate electronics and battery are strategically mounted on the tube to spot the center of gravity just about equidistant amongst the rotors.
But is it flyable? Yes, but just barely. The online video down below demonstrates that it absolutely receives off the ground, but does a ton of bouncing as it attempts to discover a stable angle. [Paweł] appears to be to think that the gimballing servos aren’t quick sufficient to make the thrust-vectoring adjustments wanted to maintain a adhere flying, and we’d have to concur.
This is not [Paweł]’s to start with foray into bicopters he acquired “Fail of the Week” honors back again in 2018 for his coaxial dualcopter. The flying stick would seem to do substantially improved in common, and kudos to him for even managing to get it off the ground.
