My cousin, understandably, cannot let my car be so much faster than his so he will be changing gearing as well. The difference is he would like to stick with 48P gears for some added durability with the target ratio is something in the 4.3 FDR range. I tested 55/33 with some spare gears I had and they did not come close to meshing so I'm thinking something around 60/36 would work. Can anyone give me a 48P recommendation for a 4.3ish FDR that will fit?

I'm looking for gearing in 48P to get a FDR in that range to prevent buying gears that don't fit. Like I said, the first guess with 55/33 gearing did not come close to actually meshing.

You can get the high speed gear set, then order what ever 48P gears you would like.

WHile he did use 64P, you can use this as a guide for 48 as well.

What gears fit on the tamiya high speed setup. I need to regear for the 17.5 and want to make sure I get a 64p that will fit

Cool I was thinking they would fit but wasn't sure the pictures I was seeing of them made me think twice about ordering right away.

These are the gears I'm using in my TB03. I believe they can be used with the TT02

be careful going to small with the gears, I originally bought a 77T spur and a 44T (64P) and the diameter of the motor prevented the gears from meshing, not enough adjustment travel. I then went to a 85T spur and a 51T pinion and that put me pretty much in the middle of the adjustment on the YR adjustable motor mount.

As long as you go with a spur around 85T (64P) you can cover a wide range of FDR's.

Cheers,
Jim

That's where running wider-pitch gears comes in handy -- the teeth are taller as well as wider, so even if you can't get a *perfect* gear mesh due to limitations in the motor-mount adjustment, you can still get an *acceptable* gear mesh. 48-pitch (aka Mod 0.53) gear teeth are about 0.35mm taller than 64-pitch gear teeth, which means you can get away with having the motor positioned about 0.7mm further away from the spur gear than is ideal, and the gears will still mesh well enough to drive the car. If you can make the jump to Mod 0.6 without losing the ability to get the gear ratio you want, you can get closer to 1mm of leeway in the gear mesh.

Hey Jim,

I run 78T/51T on my TT02S for racing which gives me a 3.98 fdr. The motor I use is a 21.5 and it never temps above 120.

You will need to grind the gear cover, mine has an opening.

Roughly equal to a 80T 64p.

This thing is a mess of tires right now. Hpi is not on my good list at the moment. can't find tires wheels are impossible to get. 🙁 Either way I got to run it a little bit. Running 82t spur and 49t pinion she scoots pretty good. Doesn't seem to turn very tightly. Guessing I'd have to put cvd's on the front to get better steering. I have new tires ordered and some mismatched wheels also coming that I'll just paint to make them match. Quick picture I snapped.

Rebuilt my TT02S with the white hardened chassis last night. Looking forward to see how much handling improves on carpet.
