so im going to be runnign mod 12th scale from now on and i noticed that the kr wasnt to hot in 12th scale and i noticed that most peopel run the pt but isnt the pt just a kr with standup brush hoods and a small size comm so could i just get some standup brush hoods and slap a small comm arm int here and have a pt? plus what brushes work the best to get the full time out of the motor. i ran blue springs with the kr and it made the heat jsut fine but i wasnt much faster than a stock car in the last minute or two and any help with the motor setup would be very helpfull
