Testing Servo's, ESC & 450 motor

I recently wired up my new 450 electronics setup, and realized I could test it with my $5 servo tester. Excellent way to test before you install it in the heli. Same Battery ESC & motor setup in ALL my 450 helis. The BEC was meant for FBL setup, but was not needed, the 40Amp esc, BEC has plenty of power for the 3G and 4 digital servos.
