I got a nice hard whack while racing the other day which put my steering out of whack veering the left of which the trim couldn't correct. I had to disconnect the servo, re-centre, adjust my trim and connect to servo to fix.

However since then it seems any small impact results in this happening again.
Very frustrating since i have to fix mid race meaning I come last.

I'm just a novice so not sure what to look at to fix.

There is a motor inside your servo with a pinion pressed on the shaft... I bet that has broke loose and is causing this. Send it in or get a new servo.

Check the servo horn as well, might have messed up teeth.

Thanks for the help. I'll check it out. Are some servos better than others at taking an impact in crashes so to avoid this happening a lot?

You can definitely do better with a digital metal gear servo....I guess that depends on what servo you're running now. A servo saver sounds like something you should run as well, check with the other racers and see what they're running.

Sounds like the servo arm, even if it feels like it goes on decently it can have the teeth jacked up and slipping, id just try a new one, just make sure its the correct tooth count for your servo.

Thank you for the help. Much appreciated.
