3.8 -> 4.8 kg of thrust needed
I need a power system that produces 3.8 -> 4.8 kg of thrust with a propeller no larger than 60cm. Does anyone know what kind of motors I should be looking at?

I have several Scorpion 40 series motors that can all do 4.8kg thrust without effort. Props from 18'' on down depending on KV, all on 6S for me!
Go to Innov8tive Designs.com , download the latest calculator (free), then you see for yourself the individual specs.
I tested a 4020-16 with a 18/10 Apc e, pulled 1500 watts, at 70 or so amps, produces about 14 lbs thrust (6.36 kg). just a sample.
The Scorpion calc is quite accurate when using props they tested, usually within 1-2%. FWIW Doug B:D

Thanks, that was exactly what I needed.
