I'm new to RC cars and I'm afraid I'm getting hooked. Been having some problems though. I bought the mini summit a few weeks ago and have broken several axle driveshafts during that time. I spent the morning installing new steel shafts from traxxas. Three of the Four axles work great, but the rear right constantly pops out of where it connects to the diff. It seems like the shaft is a millimeter or two short, but I doubt that's the case. I'm getting pretty frustrated, any input would be appreciated.
