Accidentally aye MetalMan??? ;)

Ok, 30-40 MPH depending on the track. The LHS is 2.5 hours away so this car does see plenty of street time. The speed calculations were with the 2.5" diameter street tires. The 100mph+ was on the 3.5" stock tires. The track is very small and the front straight is only 30 feet or so.

I used 3.7 volts per cell for the calculations, should I have gone much lower? I cranked up the lipo saver to 3.5v per cell and didn't see any performance drop on a reasonably fresh pack.

The buggy is just over 3.5lbs, has a 2.3:1 diff ratio and I run 16-26 tooth pinions with the 78-80 tooth spur gears. I'm going to put ZX5 pinion gears in the diffs that will up the ratio to 2.83:1 and slow it down a bit.

Not sure what the trany ratio is in my XXXT but it's not as fast with the same stuff in it.

If I could only draw what I see in my head, then afford to build it, and finaly get to play with it...
