The Joy of Technology

When Sticks Fly | Hackaday


When it arrives to hobby rotorcraft, it pretty much appears like the a lot more rotors, the greater. Quadcopters, hexacopters, and octocopters we have noticed, and there is probably a dodecacopter buzzing all around out there somewhere. But what about likely the other way? What about a rotorcraft with the minimal complement of rotors?

And as a result we have this exclusive “flying stick” bicopter.  [Paweł Spychalski]’s development reminds us a tiny of a miniature variation of the “Flying Bedstead” that NASA utilised to train the Apollo LM pilots to contact down on the Moon, and which [Neil Armstrong] famously ejected from soon after receiving the craft into some of the attitudes this very little machine uncovered alone in. The bicopter is one of a kind many thanks to its fuselage of carbon fiber tube, about a meter in length, just about every finish of which holds a rotor. The rotors rotate counter to every other for torque command, and just about every is mounted to a servo-managed gimbal for thrust vectoring. The manage electronics and battery are strategically mounted on the tube to area the center of gravity just about equidistant in between the rotors.

But is it flyable? Sure, but just hardly. The online video beneath shows that it surely receives off the floor, but does a great deal of bouncing as it tries to obtain a stable mind-set. [Paweł] seems to consider that the gimballing servos are not quick plenty of to make the thrust-vectoring changes needed to keep a adhere traveling, and we’d have to concur.

This is not [Paweł]’s initially foray into bicopters he earned “Fail of the Week” honors back again in 2018 for his coaxial dualcopter. The flying stick appears to do significantly improved in basic, and kudos to him for even taking care of to get it off the ground.
