Dennis is right about the braids - the length is important and I would suggest that the optimum length exposed might be just slightly different for different makes of track. A little bit of experimentation will pay off here.
The other point to be made is that the standard TSRF supplied motor is very fast indeed and needs at least 1 whole amp of juice for EACH car in order to realize the full potential. So, not less than 2 amps for a 2-lane track and double that for a 4-lane track- AT LEAST. New users can often gain a slightly false impression by running their new car SOLO and it may well run well because the power supply is sufficient for a single car. But, as soon as a second car is placed on track, neither will run properly. This is NOT a down on the car, simply a reminder that adequate power supply is necessary because these cars are a step up from the more familiar low-consumption home set vehicles.
Other than that, these cars are GREAT!
