For the prototype models we have used the following equipment.
Quantum 2 15 or 20 or 25 motor
Beetles 30A ESC - 60A ESC to suit above motor and prop selection
Battery - 3s 11.1v 2200 to 2700mAh LiPo 30c
Propeller to suit motor, esc and battery choice,
2 Degrees of downthrust
With a Quantum 25 we used an 10x6 folding prop with a 50mm spinner and a 60amp esc, this setup also allowed us to try a 4s 2200 lipo which was extremly powerful and vertically out of site in seconds.
