I had no idea you get that kind of time now on those motors... & batteries too!! I have never raced any of mine. I have a couple of street cars (2spd) that are fast, but I have to tune them, use a starter box, have fresh batteries, glo-ignitor, etc... it is a ton of work just to run one car alone. Got a couple 4wd monster trucks too... they break things all the time. The ones I use the most are the buggies that are mostly stock, they last well. I think it would be fun to have a sprint car... to race a sprint car on a dirt track. Nothing here like that though. Scoot
