My V1RR has some strange behaviors since last week. Steering will jump to full left or full right at the end of straight line. I'm lucky that only few parts broken so far, no serious damage yet.

I tried different frequency crystals but still unable to solve the problem. And I notic this problem will only happen when I do full speed at straight line. If I do half-throttle only, go slow, everything is cool.

My V1RR using both Futaba 9550 on steering and throttle. I know 9550 is a little under-power on GP steering, but is the under-power servo will cause something like sudden full left/right at high speed? Or something else could cause the problem?


It's really bad to see my V1RR airborne 3 times in 2hrs...

I just found out my servo saver's spring become kind soft. I can turn it with my hand easily. I made a pair of pin to disable servo saver's function but don't know it's the source of problem since I dont have chance to play it until next weekend.

Maybe it fix the problem.. who knows.
