Weird Radio Problem

[madnking]

I had a JR xs3 and a novak xxtra receiver and my radio it went bad so I bought the Xs3 Pro and after I installed it I started up the car and it idled fines and under short idle bursts it ran well. When I was hard on the throttle for a few seconds and let off the throttle it would rev uncontrollably and for a few seconds. Then it would be fine until I was hard on the throttle. Any help would be appreciated thnks

don't think that is a radio problem. I think that you may have a tuning problem with your engine. If you say that your engine revs incontrollably for a few seconds after you let off the throttle? Have you been trying to mess with the needle settings recently?

the servo is going crazy back and forth back and forth for two to three seconds. I watch the servo spas for a few seconds. I switched to the jr stock receiver and it doesn't do it now.
