Thanks, that makes a lot of sense. The R instructions seem to be right in the middle-ground of settings, so maybe I'll go with that to start.

Old dog new game. What's the TT02 max min tooth count of the pinion and spur set? Largest pinion and spur and the smallest pinion that still reaches with the same spur. I have the YR motor mount and spur adapter (high speed gear set) on the way. I'm looking to end up in the 3.8 (55/36) FDR range for some 21.5 racing. The car is an SR and a WHIP. I'm waiting on a few more deliveries before I can run it. I'm also getting all Tamiya upgrades to stay TCS legal if we ever get to race again.

Thanks,

John

With the Tamiya motor mount, you can run a 29T pinion with the 64T spur. Gets you down to 5.74

New shocks included a holder (from sprue) some assembly required.

It should be here tomorrow. I can play with it. I have a few TC3s laying around for comparison. They are the reason I went with the SR version. Hope to see you and the other racers this weekend.

I've got a set of TRF pistons that I need to put in mine. I'm too lazy to take them apart just for that.

How many holes do they have? I'm using the single hole pistons one these same as what they came with. Pretty easy maintenance really was expecting more of a pain. I used our food vacuum sealer to bleed the air out lol.

I finally got a set of springs in but somehow did not notice they only come with 2 of each spring. So now I need to order another set. I'm gonna run the stiffer set in front for now.

I got the 3 hole ones. I tried running with really stiff springs all around and didn't like it. That might work well on carpet, but I wasn't getting the traction I wanted on asphalt. I may actually go back to the softer kit springs on the rear.

Ok need some help.

I’ve just fitted a Tamiya 64T spur gear, along with a 48P 28T pinion gear.

I'm using the standard plastic motor mount whilst I wait for my YR adjustable one to arrive.

I’ve got it to fit nicely, but it sounds awful!
Like a sort of grinding sound. Previously it was nice and quiet, but after fitting these bits, it’s very loud. Is that normal, or have I done something wrong?

I have greased the gears too.

Did you use a Tamiya pinion?

No, I couldn’t find one that was 28T.
I bought one from eBay.
Forum won’t allow me to post the link, but the item number is 274341095112

The Tamiya aspur gear (Module 0,6) does not match the 48dp pinion.
If you convert 48 dp into the metrical system you will have module 0,53. (1/48*25,4)
Vice versa: module 0,6 is more equivalent to 42dp.
​​​​​​The result of the combination with real module 0,6 is not smoooth, but "pepper mill"

Kremzeek, kremzeeeeek!!!!

So that will prevent the grinding sound with the Tamiya 64T Spur gear?
I can't see what the difference is with that pinion compared to the one I've purchased, unless it's just the coating?
