I recently pciked up a 3pj + some servos. Most work ok, but I'm having a problem with one of them. Its a 615BB, and WHENEVER I have my power switch on, it starts turning to the left, without an prompt from my Tx, I plug in another servo and it works fine, put the 615BB back in: same thing. I took the servo apart to take a look @ the gears: and they look fine, the wires look fine [no frays, etc]. When I connected the servo with the gears removed, the thing just kept on spinning!!! Its a pretty decent servo [I have 615BB converted to MG in my RC10GT and I LOVE it: MG conversion b/c the first day I had it the nylon gears stripped] and I'd like to salvage it rather than just trashing it. Thanks in advance!
