spacers where? shoudnt the hudy side plates fit right up to the hub? the 210 axle is too large to fit through the hudy 1/10 side plates.

Its been mentioned before somewhere, the FDR is the same in both 3 and 4 gear

i cant for the life of me figure it out the idler gears on the four gear are 28t and the gear are 34t. since the 28t's are the same size they equal each other out and equal 28t. i dont know how you can make 2 28's equal 34??

So the diff gear and the top shaft gear are the only two gears you need to worry about when you talk about FDR

The idler gear is irellevant. As all the idler gears work by them selves and not on a fixed axle, all that matters is the first gear (the layshaft gear connected to the spur) and the diff gear. There could have been 500 gears in between in various sizes. As long as they work on their own axles it doesn't matter.

edit: Bah... Tamak beat me to it, and even gave a better explanation 8/
