Forget about those servos: DON'T USE THEM ON A PLANE!!!!!

I' bought three of them and get really dissapointed: no centering, no presicion and several "blinkings" even without input. ANother thing: if you open the case, you'll note the worrst electronic cardboarding setup ever seen. There isn't any protection against vibrations nor shocks, wire soldering is just embarrasingly bad...

Mine three are there, in a box waiting for some car or kid's toy... O don't know.

Hope it helps.
