I use Acer Racing ceramic diff balls, they never seem to wear, and the diff lasts for ages before needing a rebuild. You can also get Atlas diff covers to protect it from the dirt getting inside. I usually can't remember when was the last time i rebuilt my diff when it gets on needing a rebuild. Only thing I know is I never rebuilt my MSX's diff and it's still smooth as new, with 2 months of racing behind it (ok i've not raced that much in january but still...).

Belts, on my not-MSX car I've been using the same rear white belt for months and months and it never seems to wear. The front one, when using a spool (with the fixed centre pulley of course) I broke 3 belts that weren't that old (not more than 20 runs, with putting a new fixed pulley every time). When running the black belt on front never had an issue. This don't seem to happen when running a one way with the one way pulley.

I'm now running a home made bigger centre pulley with adapted belts and I'm very pleased with the efficiency and wear of that combination. It can get hard to gear low wind motors for indoors but I don't really run them in those conditions anyway. I'm having Tryhard give that combo a go to have his opinion and then maybe I'll get it marketed.

Any pics of the winning car?

Did Marc used the new steering system and the TA05 pulleys?

hi. i know to tighten the front belt you turn the belt tensioner anticlockwise when looking from the RHS of the car. i.e standars is at 12/6o'clock and tightening it will be at 11/5o'clock

which direction do you do the REAR belt tensioner to tighten it?

i only have the MS and dont want to do it wrong way as it would take me half an hour to try out.

The notch on the bearing holder, if you move it towards outside the car will tighten the belt, no matter if it's front or rear.

cool that makes sence.

also with regards to stronger belts. i have been running my lightweight belts for about 2months in and showed little wear. then i ran mod for first time and the belt is nearly trashed.

Has anyone tried the ECHO or the RUSH belts? they are supposed to be better? Anyone know where to get from?

Does Maezumi's MSX have a different spur gear holder? The reason I ask is bcoz the spur gear backing plate is on the opposite side.

bender: Cheers mate.

JRRobiso: I think its a carbon fibre plate to stiffen up the spur.

It looks like it has nylon pullies on the layshaft so it may be a new gear holder and pullies to match the larger diff pullies

Hi Alan,

The truth is that the drive train u are seeing on the MSX from the Tamiya team is from the TA05. they also have a new steering bell crank system on the cars. According to Marc and Satoshi this 2.25 drive train from the 05 is actually smoother than the original one how true i am not sure.

Cheers.

If you look closely, the backing plate is screwed down with blue countersunk screws which is what we already have on our backing plate but it looks like the spur gear was flipped. Normally the backing plate on our 415s are facing inside the center pulley not facing outside or away from the center pulley.

maybe to fit a pinion on better? who knows..

Did you guys notice that Maezumi's car has a Checkpoint motor? Isn't he sponsered by Team Orion?

yeah, i realised that when I looked at my car, lol.

I heard about this pic online at the track. It is nice to see that they have fixed the steering bellcrank system. It was really my only issue with the car when I bought it. I hope the fix goes into production soon. Also did anyone notice the black belts vs the white ones? I have seen a few fray, were they were replaced with the black.
