Thanks for the response. Still having some trouble understanding the clunky google translation... Especially:
"And finally for today, part of the structure that caused the greatest difficulties, but has found a simple solution.
This is how to get rid of the backlash in the axes of the gears. I had to drill a slot f2.5mm in landing gear shaft diameter 7mm. Next, cut the Greatest shaft length and cut in the resulting f2.5mm hole thread for M3 screw. The landing gear itself pressed into a hole two bearing outer f7mm and ext. f3mm but unnecessarily gouging gear slightly and for a long time does not have 7mm, then save gaskets AMG2N foil thickness 0.03mm - this foil for honeycomb MiG-29, a very good thing in everyday life :)between the bearing bushings as the two approached the ideal Gadget . All assembled and installed on the end of the Safety-nut - all clearances defeated:)"
Drill a slot in landing gear shaft? Wat.
I'm going to get a second MSFFB2 in a couple of weeks, so I'll sacrifice that one for some experiments. It would be nice to know exactly what kinds of bearings, tools and other misc. stuff you'll need for this mod.
