Been running a 65' track at a Community Center now for about 6 months- everything is going great! We have big interest, participation of all ages and a core of regulars who have purchased cars and are looking to start a league this fall. The current problem we are having is that the lange changing switches on the controllers are breaking. Hard to describe the mechanism that is failing, other than to say it is a dumb way to get the job done. There is a small C shaped piece of metal that acts as a spring of sorts. This tiny piece is failing and there is no way to repair it. Talked to Carrera USA and they can't get replacements though they are sending us two replacement controllers free of charge!! Maybe customer service is turning around in the US. Anybody have any options for me? Replacement parts from Europe or an aftermarket controller? I hate to think about having to replace $50 controllers every 6 months for the life of the track! Help anybody??
