Can you try a different rx or tx? If they still do that I'd send them into Hitec for examination. They are very good about helping customers out.
ORIGINAL: heads-up
No its not power hungry i have a 5-cell in there that was off charge and i checked the voltage it was like 6.2+ with a load i have the airwild heavyduty extensions and i hooked the servo's straight to the reciever too and they did the same thing, the funny thing is that i have a 5645 on the rudder and my elevator is a 6985-hb digital coreless and they both work fine with me wiggling all the surfaces to get most current drain, and i never ever use y-harnesses and im not going through the maximum arch on my servo rates too so there not locking up i mean i trust my friends word on everything 100% he does this for a livng and he even said there is a problem with the servos, i just wanted to get the word out because i almost crashed my $2000+pattern plane. i have also heard that hitec is amazing when it come it comes to customer service but if something would of happen what could of they done,Dean
