Application(s): .30 size nitro helicopter (Hirobo Shuttel 30)

Comments: Tested on table, installing and programming radiotransmitter, checking servo reverse and end points, testing throttle, and once the servo turned to into its endpoint, making vibration and force its own gear, as it wanted to tear itself, almost breaking the servo arm in the endpoint, pulling the rod with high force.
As I obsertved it, disconnected the power source battery, checking the whole system, especially this Hitec 925MG high speed throttle servo. It has been (electronicall) damaged, possibly caused by a Hitec 5 cell 1800 mAh 4/5 AA size NiMH battery pack's voltage, since it has been over 6 Volts.
Note: Be sure to operate this servo 4 cell NiMH battery and before testing or operation, check the battery's fully charged voltage, it must not exceed 5.9 Volts.
