Re: Off season FRC quadrocopter build

I don't want to be a dream crusher but to get the proper rpm to run a reasonable propeller(Cim tops out at about 3000 rpm under load) you would need a gearbox which would add more weight to the system.

To put it into perspective each motor on most quads have the same power as a cim and even with there lightweight, high discharge Li-Po batteries and electronics they still need 40-50% throttle to fly. To even make a cim copter hover you will be looking at using 90-100% throttle which won't leave any headroom for stabilization making a very unstable platform if it flies at all. Maybe if you used a LiPo battery and replaced the cRIO with a lighter controller it would fly but just barely.
