i still can't bring myself use hitec servos, because of my heli flying. i can't trust hitec in a heli. if it fails (in heli's, hitec is known for failing) it will cost me around $500.00 to fix a crash. i stick only with jr servo's and haven't had a hitec for 12 years. seems to me they have the car/airplane market covered, but, heli's have too much high frequincy vibrations for them to handle.
