Not that i am trying to get off the subject, I am having trouble getting enough "punch" out of the car in stock. I run on a tight carpet track and have both the TC3 and the losi and can not get the snap out of the corners that the TC3 gives me. I have tried going to the bigger spur and had little effect on the problem. All the grease is out of the bearings and is freed up alot. I have not tried the one-way yet . Any ideas????? Thanks
