Mike - Pinion-Spur Gear Adapter
 

I was looking at some outrunner setups today and people are running 25+ tooth pinions. At 15 bucks a peice, this would be a real bill to those trying to find the right gearing with outrunners.

The one problem I see is that spur gear tooth counts only go down to about 35 or so. I'm sure we could probably come up with smaller ones, but mike, you may need to help us out on this too.

So what are your thoughts/opinions? Just to keep in mind the goal of this is to reduce cost somewhat, so about $5-$8 for spure gear and less then $15 for the adapter would be what I consider reasonable.

Kershaw designs makes big pinions so does sdp-si
