have 2 servos packed up at same time??

[loz]

dont know whats happened here as this seems strange, i replaced the bearing sleeve in my trex 450 last night and now the elevator and aile servos have stopped working, iv checked all the obvious, plugged working servos in a working channel on rx and they are fine but when i put the offending ones in they seem to be dead, there not jammed either, any ideas what might have happened peeps ??

Are you saying you have two dead servos or two dead r/x ports.? Plugging a known good servo into all the r/x ports in succession will prove the r/x serviceability, doing the same with a suspect servo will prove it's duff or not. Plugging a suspect servo into a known good r/x port and tugging, twisting the leads at each end may show a wire break. But for two to go at the same time looks like a r/x snag on the face of it.

the rx channels are working fine, and when i plug either of the two non working servos in theres nothing, so im assuming something has fried them maybe but dont know why or how?

Perhaps if you stripped a duff servo down and found obvious signs of frying you'll know for sure then, as to what caused it you'll probably never find out.
Hate to say it brother but, "Sh*t happens !" Managed to fry 4 servos, ESC and gyro on a 550 when the enter programme mode failed in the ESC, brand new as well, real bummer and still don't know how as Robbe ain't doing anything about it yet since several months ago. Being told he's not helpful at best of times is no compensation at that level of bucks.
