Hi everyone!

I just finished building my first buggy - Hyper 7 Sport BUT after installing the servos and turning everything on there seems to be a problem with the radio/servos or some interference. The car twitches and the servos move like crazy on their own but it only happens when a specific servo is plugged in - Hitec HS635 for the steering. Can anyone offer any suggestions as I want to sort it out for the weekend so I can break the engine in. My guess a faulty servo......
