its most likely the servo settings. after a radio change things like endpoints, trim, and others will change, most likely the zero setting (middle) of this new radio is different then the old one. take the horns offa your servos. trun on the radio and center all channels (remember to trim em to zero as well) now re-attach the horns so they are in the proper place for each channel. striaght for the steering and just at idle for the throttle. now go ahead and change any endpoints and the what not.
