The SMR NASCAR class has used stock Scalextric "black stripe" FC-130 motors for many years, but lately we noticed that the newest motors do not perform as well as the best examples of motors that were bought two years ago. The best motors that I have are good for 23K RPM, but we sorted through dozens of new motors and could not find a single one that was good for more than 20K. We thought that new racers especially would be handicapped, so we have switched to the Piranha motor as the spec motor for the NASCAR class.
