Has anyone purchased a MDC RTR HOn3 Shay? I purchased 3 of them and having trouble with the same thing on every one of them. The gear on the driver shafts loosen up and spin on the shafts leaving the motor running and engine standing still on the track. I'm trying out the NWSL replacement kits but haven't completed changing them yet. Has anyone else have this problem? I tried writting Athern since they bought MDC and can't get an answere. Any other advice????
