Can someone please help me out by telling me the deal with the Kawada Spur gears? These are the ones in specifically referring to.
My questions are the follolwing:
1) What size diff balls are these supposed to use? Some people tell me 1/8 some say 3mm. I have both, and both seem to fall out.
2) On the topic of diff balls falling out, apparently the diff ball holes are kind of one way, so the balls are supposed to fall out one way, and stay in the other way.
If anyone can shed light on this matter for me it would be greatly appreciated.
