rc10t 40mph?

[SpEEdyBL]

A 380c 9t on 3s will do 40 mph no doubt. I once had this combo in a xxx-4 and it was a rocket. Out of all the feigao motors ive owned, (380 12s, 380c 9t, 540 6s, 540 9L, 540c 8xl), the 380c 9t was definately my favorite. But unless you are limited to feigao I recommend the mamba motors, which are better quality. A cm4600 should be very close to the 9t in performance.
