BrianG, as you may already know the 40T mod 1 spur comes very close to the chassis. There really isn't much room for a larger Mod 1 spur gear. With a 48P spur you can probably squeeze in a slightly bigger (numerically more teeth) gear because they are physicaly smaller. I may go that route eventually, if track testing shows I need the gear (lower) change. The slots on the mount are pretty much as close to the edges as you could make them. As I said you would have to drill and tap new screw holes to be able to use smaller Mod 1 pinion/spur gears. The accelleration is fine, I was just a little worried about the top speed, which would require a smaller spur/pinion. I need to radar my nitro Revo to see how they compare, I don't trust the Traxxas advertisments (40+ mph). Also, I don't think the gear box was shifting into 2nd gear. So I need to adjust the transmission shift point to make it shift sooner, to see if this makes a differnce. Overall I am very happy with the conversion, because with one as complicated as this it normally takes several prototypes to get it perfect. And there is a lot of fine tuning that still needs to be done (gearing, close ratio gears, shifting adjustment, more powerful batteries, different tires, battery placement, CG adjustments, etc.). This will require track time and that will have to wait until the new year..
