Designing a Quadcopter Power train

[jack_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.
