Right, just so you guys know, I have sent an idler gear away, to be copied by RW Racing, so you can have a machined idler gear. Tamiya only sell the gear in a pack with the diff gear.

Well the same car lost its 3rd ilder gear last nite, and a second care lost its first..... My self and one other driver have logged the most laps with our cars and have not seen this failure...yet.
we are at a loss as to why this is happening. i beleive a gear box case is going to be ordered to try out.

Below is a quote from Randy Caster (TRF driver from the USA) found in RCTech's forum:
"Tamiya has recognized an issue with the idler gear material, and are already working on a more durable material. Some people are having issues, some aren't, I think it has a lot to do with how much motor you are using, and making sure your diff/slipper are set correctly. For anyone building, or rebuilding their 201 transmission, before installing the idler gear, boil it in water a couple times. This will help to soften the material and make it less brittle, and should hopefully solve the issue altogether until the new parts are available from Tamiya. If you do happen to strip an idler gear, I would recommend replacing the diff gear and idler gear. This is basically just to be sure that none of the teeth on the diff gear are chipped or cracked and would cause another failure." .

boiling! Wow have not hear of that since the old AE pan car days! LOL Oh and HPI with there PRO3
 Oh well At least they are on top of it. Wont hold my breath about Tamiya handing out next gen gear sets to early owners though FYI: At my club we run 13.5 motors. most have turbo/supercharged software in effect and the track is a hard packed small indoor track.... Everyone running the new car has years and years of race experience so slipper settings should not be the issue, but worth looking at.

It might sound like blasphemy but the gears from kyosho rb5 (um509) fits in the 201.
The diff gear is identical but the idler is 26t instead of 27t. There is an optional 26t idler in delerin (umw513)

Ticking time bomb is a good way of saying it!! Has anyone tried boiling them and done decent mileage after? Also, how much grease are you all using on the gears when you build?
There's no doubt this is an issue, just wondering what can help mitigate it!?

looking at it and after chatting with Dyna, if it is going to go, it will go early, otherwise it will run and run, to do with fibre alignment in the mouldning

Right, have spoke to RW Racing, idler gears should be released middle to end of next week, you can buy them from
www.fusionhobbies.com or http://www.m-k-racing.com/ They are machined out of solid material, and the usual very high quality RW standard.

no worries, should be miles better than the kit one (which is unusual for Tamiya), plus you wont have to buy it in a pack with the diff gear.
