SimonK ESC FW – test of commit 1f75da – #2

X450

SimonK commit 1f75da: (20140313) with COMP_PWM was loaded on the F-30A ESCs on this X450 quad with APM FC, 3S, Hobbyking D2836-8 1000kv motors and 11×4.5 SF propellers.

Performed rapid acceleration under WOT, motor idle, recovery, maneuvers and no issues, no hint of sync problems, works fine.
