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.

OK, thanks, I'll keep that in mind. Looks like I might as well do the dremel mod. I don't think I'll be traveling too far outside DSM unless I really get into racing, so HH is about it.
And you're right, I figure around 36mph with my setup. Really, that's fine as I plan on keeping this strictly for track use. But you never know. :)
