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......

if you mean it twitches and buzzes at neutral, thats normal. but if they do move 'like crazy' check the routes of your wires to make sure they cross over as little as possible and check for loose metal to metal contact[8D]

Secondly try another frequency of crystals as sometimes local things affect the signal. But the Hi-tecs are known for bad centering, but as yours is new then, I'd suggest the crystals first. Obviously your on AM and this does happen a lot.
