Yes sir last year I ran a Cen Matrix Arena FRE I lightened the heck out of it but still wasnt light. I ran weekly against A guy with a Losi 1.0T with the OS .28 another guy with Jammin X1CRT Jammin .28 and on the straight If they were in front of me I caught them by the end of it and if I was in front of them I pulled away. Now not like they were standing still and shure clutch driver and other things come in to consideration but thats the way it went. I was runnin Mugen 1.1 springs and Mugen shoes with 8mm restricter mostly, some times a 7.5mm.
