Hey B4maz, where did you get your spur gear? My motor mount doesn't allow me to gear much higher, so I need to get a smaller spur. The spool axle is a different diameter than everything else so I'm having trouble finding gears that will fit. I'm looking for a ~40T delrin gear.

I got my gears from http://www.sdp-si.com/web/html/gears.htm

Go under spur gears and pick out the one you need. I ended up using 32p gears. I think the Ultra GTP comes with mod 1 gears. so you'll have to play around with the menus to see if you can get a 40t mod 1 delrin gear that will fit. The spool diameter is 8mm and you can get gears with a bore diameter of 8mm. I think this should work:
