I received my WSN T34 in 2006 and it STILL has the plastic gears in it and has been battled with at least half a dozen times... inside though. I backed up the gears on the shafts with CA and then really packed the gear box with the ceramic grease that is included in all the Tamiya FO kits. I believe this keeps the gears from floating around and provides enough lubrication there where it's needed.

Of course, I put bearings in all my road wheels and sleeved the idler wheel with brass along with an aluminum suspension Daryl Turner made for it.

I bought the metal gear replacement set for it right after but it's held up so well, why mess with it? Besides, I have heard the metal gears are very noisy anyway. I use that oil that Radio Shack offers as it's a blend with Teflon in it and I put it into a needle applicator bottle.


I think if they are going to be put outside and used I would put a full gearbox in and an idler system too as well.
