John,how are you?What wind KC motors?I normally run Checkpoint 10/11/12 doubles,geared 88/40-43,depending on the wind.But it's still velodrome racing and i throttle drive.Probably won't be the case on a 400' runline track.

Hey John I'm not totally sure what the run line is now. It looks like about 400' or so but the QMA web site says that a track cant be more than 1/20 mile run line. That calculates to 264' run line. I am going to try and bring a wheel so I can roll it off Sat. To me it looks a lot longer than 264' but QMA says that the track length. Who knows, all I know I'm maxing my rpm out half way down the straights running the same gear that I run at Easley with my .09. I know I'm carrying a lot more speed into and thru the turns. I guess we will find out the length Sat morning.
