Hello

I just purchased an aggressor radio, with one servo and receiver.
When i installed it in my car it is extremely twitchy. I can't even drive the car.

What are some suggestions to cut down on the twitching?
I have one Hitec servo (on throttle) and a JR servo (on steering) Could this be the problem?

How can i check if the receiver/servo is faulty?

Thanks

It sounds as though your radio might have been sitting for a while before you purchased it. When this happens, the radio can fall out of tune. Please send the radio in to us as you are still under warranty. Here is a link to the procedure on sending the radio back to us. http://www.hitecrcd.com/pages/support/102

Should I just send the radio, or the radio and receiver and servo?

Is there anyway for me to check if this is actually the problem?
Can i repair it my self here?

Thanks!

You can send all three to be safe.
but, the main items are the Tx&Rx
