I have a wierd glitch problem that bothers me. Here's my set up. rc10t4, novak gtb, brushed vantage 14x2, airtronics receiver/transmitter, and airtronics 94357 servo. The esc is set in brushed mode and the cap that came with the gtb is connected. Here's the problem, the truck works fine until it gets 30 to 40 meters away at which point both the speed controller and servo glitch really bad. They don't hold steady to the point of a runaway they glitch on/off really fast. When I bring the model back it works fine. Seems like a range problem but I have for 100% eleminated the radio, receiver and crystals as the problem. They all work fine on other models. Any thoughts on this would be great.
