Not a problem, BT. I just shudder every time I see a post about breaking in the TU's.

The Tamiya system is very well thought out. Motors have internal suppressors, as do the after market Graupners I sell (out of stock at the moment but due in any day now...finally). Basically you have a very well thought out and quality built unit here. The entire system is plug and play, although I do replace all my motor connectors with low resistance connectors, and do the same on the batteries, carefully matching polarity on the batteries by the way. Basically you are getting what you pay for. Tamiya TU's can be worn out, as I have done to a couple over the years, but you can get an inexpensive kit to overhaul them, basically a kit to replace everything but the TU frame, from Danville Museum or Tamiya in CA. It took 5 years of hard running and many a competition at Danville for me to wear one TU out. Normal driving, I doubt if you will ever wear one to the point of needing replacement gears, but if needed they are out there.

Steve, with your special competition TU's, I do run them an hour in each direction with the TU motor, clean them up, re lube them, and run. The more they run, the more quiet they get.
