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

TowerHobbies.com | Robinson Racing Spur Gear 60T Stealth Pro

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.

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.

cool. found it at Rcmart - cheap too.

Tamiya 1/10 Honda NSX-GT Lightweight 2005 Clear Body Parts Set #47353,

Roughly equal to a 80T 64p.

Yep they are even available in Europe so I have a couple. They are not legal in TCS races though. (Although that probably doesn't affect you in Australia)

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.

What brand spur gears are you running?

I got a kimborough but had to drill 2 new holes to be able to use all 4

Just an FYI I am running a spur with only two fastener holes and I have 30 packs through the car with no issues.

I ran the car a bunch this weekend, it is amazing how much difference the ambient temperature can make on running temps. The other day running the car in 90* temps and 115-120* surface temps the motor was right at 155-160*. On Saturday we were right around 70* ambient and overcast, surface temps were right around 80* and the motor never got over 135*. I also think that my two packs may be getting softer, one does not have a lot of cycles on it but is like 6 years old, the other pack is 18 months old but has over 100 cycles. I treat my packs well but you can only ask so much of them. Can anyone confirm if the Gen Aces 2S 5000MAH 50C packs fit in the TT02? They seem to get good reviews and they are nicely priced.

Cheers,
Jim

Gen ace batteries are good for the money. Not sure if they fit. I've got an smc 6500 that I know fits in there just right. They are good bang for the money good quality.
