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 , 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
