3D printed tandem helicopter.

Full function tandem helicopter. Roll, pitch, yaw and collective with a single motor.

The gyro struggles to control the roll axis despite using holes super close to the center of the servo arm. A better gyro would fix it. I might make a setup with more leverage for the roll servo instead.

The extra lever for the pitch servo is there to increase the leverage and resolution for that very reason as I encountered the problem in pitch first.
