Default Servos???

I have a HPI RS4-3 and my servos are going crazy. They twitch, both the throttle and the wheels. I changed the batteries in the car and I tried messing with the trim. What could be causing this twitching?

It could be interference in your area, or try and take the crystal out of the reciever and clean the connections on it ( I had this similar problem B4).

Hope this helps

Check if the receiver received any fuel over it ...

Isolate everything... by that I mean, systematically isolate what your problem area is. Install working servos to the reciever, use different a radio system you know is in perfect working order, etc. If you don;t have extra radio gear, nor a friend with extra radio stuff, take it to the hobby shop... they should be able to do this for you as well. I mean you could have a bad battery contact plate in the battery plug, a fried reciever, broken crystal, horrible glitching- among many other things.

But most likely, this is something to do with your reciever. Like Tabushi asked: did fuel, water or just a load a of crap get inside your reciever ever?

I drove the car yesterday and didn't seem to have a problem, so maybe it was an interference in my area. I took out the receiver and everything seemed clean and it did not look like any thing had been in that area.
