bearing mod

[Lowie]

I've read about a bearing mod, but couldn't find any explaning pictures about it. Does anyone can explain me this mod? maybe with somepictures?
It is just out of curiousity, I understood that the X10 goes very fine without spur-probs when correctly build.

I think it involves putting an extra bearing between the spur gear and end pinion. Cant' remember exactly where if i'm honest - but i'm sure you'd find info at "the pred" site. I never did do it, just fitted the rings that were supplied on the pinion/prop joint and never did have any problems with gears or spur - still origional of all after a season's use.
