September 3, 2011Application(s): Tail rotor servo for hk500 belt driven helicopter
Comments: Bought 3 of this for use of my helis. 2 died after less than 3 flights. Used 6v setting on my hobbywing platinum esc and kds 800 gyro. Other servo installed on my hk450 with hobbywing pentium esc and jitters back and forth. Opened this esc and put some insulation as it seems to be affected by static electricity produced by the belt. Not really the best servo for belt driven helis i think
