Savox servo only jitters after crash
I use a Savox 1258TG in my Kyosho MP9e (1/8 buggy).
I crashed hard after a jump. Landed on a front wheel and broke an aluminum turnbuckle. Hard crash!
I fixed the turn buckle but there is an issue... When I switch electronics on the ESC goes nuts (lamps flashing) and the servo just jitters. I first thought I fried the ESC somehow but the same servo in a different ESC/RX combo has the same result. ESC goes nuts, servo jitters. Tried multiple ESC and multiple RX.
When not under power the servo can be turned. I opened it up; don't see anything wrong (like burned electronics). Gears also look fine and turn smoothly.
Conclusion: Servo fried... Somehow...
Seen this before? I haven't. Can it be fixed?

Tech Adept
the SC-1258TG is a bit below what people generally consider to be the minimum torque needed for a steering servo on 1/8 buggy. Might be worth considering something stronger.
