When does it glitch? Just on the bench or on the track too. You can try wrapping the reciever with foam rubber. Also check the servo and battery wires and make sure there is not a bare spot that is rubbing on metal somewhere. I had a bad glitching and a bare wire was the cause. Alsoo what servos are you using if they are jr then they are just dong th jr jitters on the bench but on the track they should be fine.
