i know the jr high voltage servos, you know the red and white z9100HVs and z9100HVt eliminate the need for a regulator when using a lipo receiver bat.. but are all high voltage or HV servos this way. meaning there is no need for a regulator when using a 7.4v lipo receiver battery? cause i want the HV so i dont need a regulator. and i was looking at the hitec 7050s and 7050tHV servos,wondering if these would do the trick. thanx,clay unruh
