JR DS8411 & DS8411SA servos
JLong and IMACBuff:
JR/Horizon Hobbies have admitted a high failure rate of the DS8411 and DS8411SA servos in helicopter use. If you send these servos to Horizon they will be updated to DS8311 specification at no cost. Refer to Model Aviation, January 2003, page 116, "Radio Control Helicopters."
Just got the mag yesterday, hope this helps.
Twins with JR servos, kinda' makes me nervos. (Sory 'bout that!)
