Designing a quadcopter powertrain.

[Jack_the_JOAT]

Hello All

I am working on a power train for a quadcopter - see attached the PDF.

I am wondering about the gearbox for power transmission, guessing its a bevel gear design.

I would like to keep the belt drives on the same plane.

Also, should I step the RPM down from the motor to the drive shaft? Thinking a belt or a direct geared connection might be best.

Or step the RPM down when I transfer to the belts?

Can anyone advise on what this might be called and maybe a manufacturer?

Thanks in advance.

Jack.

You need to have some type of independent speed variation for each rotor, for control. Most quad-copter stuff I've seen (mostly drones) use individual motors for each rotor.
