I've had the same gear set in my Mini since I got it in 2010-ish. There are no secrets or tricks whatsoever in the way I build it - I just follow the manual. Lubrication is next to nothing, just a little silicone oil.

Yet some people I race with seem to go through them every few race meetings.

Apart from the obvious stuff like crashing a lot and/or running a very tight diff, I don't have any real answer. It just isn't something that has affected me.

We run a 13T motor so that may add to the wear. I also have my fair share of crashes. I'll lube it up as notmal and see how I go.

I've damaged two gear sets in 12months. I'd like to get more life out of them. What you all use to lube the gears? How often do you lube them?

My idler gear goes pretty fast too. I just keep swapping them. :)
I don't use any lube on the gears. I've tried it both ways, doesn't seem to matter.

Ceramic Servo Gear Lube is always good :)

Now try to relax when you hear the next onslaught of "the mini class is being killed by the fast expensive minis! Its not driving, its the most expensive mini wins! OMG!" lol You know it will happen.

You know, changing to the oil filled plastic shocks would probably alleviate majority of your cornering issues, and these shocks come with the kits these days. I have a few sets somewhere.

Proving that a almost complete stock plastic mini can be competitive has been done before, but unfortunately people don't believe in such myths ;) My only serious objection is when someone wants to make a class rule based on this perception that more bling equals a faster mini. Its a terrible idea.

Here is Ivan posing for a picture Here. 3rd out of 18 minis in a competitive field, great effort with friction shocks. And I bet with the oil filled shocks, he would have been a place or two higher.

Hope you get the podium with your project M03M :D

He did get a podium.

The Raman Flag gives him an unfair advantage.

+1 I ran the same internal gear set for 5 years only swapped the diff gear recently to try a putty/lock setup... The one i pulled out aside from a little dirt shows no significant wear or stress on the teeth...

If you're running a stock pinion, stop it. Buy a good one. The stock one gets worn quickly and eats plastic.

If you run outdoors, especially with an 05 V2, clean the gears frequently. All of the chassis are vulnerable to grit though.

It's odd how the Tamiya pinions I use on the M-Four and SabreFD lasts forever, yet not so much in the other Tamiya m-chassis and other Tamiya trucks I have.. something with the gear material they use on the spur?

Interesting servo relocation. Was that you own idea?

axle182 10-29-2015 09:45 AM

Is the chassis cut? or does it hang outside the servo 'box' in the chassis? Interesting design. why not run the servo horn the otherside? Should we start the debate about servo horn angle again? hahahaha

I like the idea of the weight offset to the rhs. Id probably run the esc in the center of the chassis to put more weight to the rhs also. Even if it raises the cog, I have often found a mini with a higher cog worked better for me on carpet, I found it makes the tires work harder with more weight transfer.

eR1c 10-29-2015 10:30 AM

agree, that is a unique setup. Why did you do it that way?

eR1c 10-29-2015 10:31 AM


I like the idea of the weight offset to the rhs.
I run a shorty pack in mine, but usually offset it slightly to the right hand side to balance out the weight from the motor that sticks out on the left hand side.

Also, do you charge your lipo while on the car? That tape you use right under the motor wires are hard to access, no?
Maybe it's velcro..
