Yea the idea of having all the spurs and a few pinion gears on hand is nice, I keep 20-24t pinnion and 54-58t spurs, the 68t spure can only be matched with an 18t pinnion or lower using the standard motor mount plate.
BTW I also don't like Castles stock monster 18t pinnion can never stay on the drive shaft, it could just be me though.
Not true! I know at the very least a 68/20 works as thats what I ran for a long time! Also 68/23 works
A Little Blue Loctite on the grub screw and even a little on the motor shaft helps keep things tight and running right.
Be Sure to get the Blue, You don't want the Red Loctite.
Red Loctite requires alot of heat to be removed. The Red holds so strong, you will strip the grub screw before it will loosen.
The Blue is made to be removeable. A good choice.
Yea I did use blue locktite, both on the screw and to fill the empty space between the shaft and the gear, and it still would slide forward, I think they just used a screw that was too small, I've since gotten some RR 20,22,and 24 tooth gears and they have a slightly larger screw and I have yet to have one of them slide forwards.
