If this is the case, reset throttle center to 0, and EPA settings to 100%. Make sure servo reversing is set to forward, and recalibrate the radio/ESC.

............do you know.......i did think about that once.......but I am not sure I checked if Thr is in reverse position........and this sounded logical......its woth to check again......

now the Quark is installed on traxxas stampede vxl with 2s x 4000mah lipo.....and it worked at first time......

I will post the result after the test....
