Schumacher KF Help me please

[markanthony14@icloud.com]

I have just bought this car. I've raced TLRs previously and now all of a sudden I can't get this car to do anything without either the servo horn or the servo itself shattering. I'm getting stupidly angry with it and would love somebody to tell me that this is a common problem and here is the solution.

Also not sure how it should be set up to be competitive. If someone could help id be majorly grateful.

Thanks,

Mark
