I have been thinking about this.
My 16-35-2 motor on 6 cells is absolutely a terrific fun flier with an APC E 6x5.5 prop.

If I was wanting more speed, and was using an ICE 100 (green ESC), wanted to run an APC Pylon 6.5x6.5 prop, and could run 8s2650, what motor would you suggest I use ???

Speed is key, but having fun is paramount, so full throttle all the way is necessary !!!!
