I'm finishing a PST Reaction, with all Hitec servos, 123 batt. Specktrum 12020 reciever.
I'm using Hitecs 5685MH for flaps, BUT, twice they have freezed after approx. 5 -8 minutes turned on.
The first ones were sent to Hitec , and they told me the motor was burned ????
Any ideas, or suggestions?

Thanks;
