To be honest, I am pretty reluctant to use HiTec
servos again. Most of them I had, had problems
within very short time and my friend uses them
on 1:10 cars (625's) and keeps changing them.
Might be the case because usage on cars but
in car if it fails it's not going to finish as balsa scrap

Price is roughly the same for Futaba's so I think I'll stick to them.
