Looking for a buggy project

[glassdoctor]

Those gaskets should work fine... they are soft adn flexible enough that the holes don't have to be perfect.

As for the gearing, 15/46 will be ok... very fast for the track. :) I'm figuring it will run about 36-38mph based on what I clocked mine at. And I suggest you get an 18T gear for some +45mph fun in the street. :027: I made mine from an emaxx lightweight top shaft.

13 or 14 pinion would be a nice option for the small track so keep the dremel handy, lol.

I did have mine geared 14/46 with the 1512 1.5Y motor at hobby haven (about 10% lower gearing than your 15/46 factoring in kv) but I went up to 16/46 when I raced at a bigger track in Waterloo so it could stretch it's legs a bit more.
