We have a few guys running them when it gets pretty warm. They seem to work very well at the right temps.

TA03 Drive Hard - welcome.

I ran my car this past weekend with a friend of mine. We put some cones down and ran a little. We both ran silver can motors. I ran my 03R(tub chassis) and he ran his 03F (graphite double deck chassis). he had me on the str8 away but I caught up to him quickly in the turns. My car cornered and turned better than his, probably because I had the front one way in mine and he didn't. When it came to the last turn I was either right on him or in front but he soon pulled away from me. I ask what ratio he had the car at and he said 4.59 FGR. He also said that he was running the RR spur, 48T with a 28T pinion. I had the same spur but I was running a 25 so I was at 5.15 FGR. My friend mentioned that the internal gear ratio of the 03's is 2.68. I couldn't find that in the manual anywhere so is this correct?

I also noticed that I had more steering throw to one side than the other. Can this be fixed by adjusting the steering link to the servo, or is this common with the 03's.

Overall I was very pleased with the handling of the 03 and with the right gear ratio I will be unbeatable in silver can competition.

Your steering throw can be fixed through the radio. Make sure you center the steering arms and then adjust your steering rods and camber. Then make sure your servo it centered. You should then have your dual rate in the radio almost exactly the same from left to right.

The gear reduction is 2.68. I fould it buy playing around with the Tamiya final drive and then just using different numbers til I put in 2.68 and I came up with the same ratios as the Tamiya book says.

The Robinson Racing gears are American 48 pitch and the setup you have is more than likely the metric 48 pitch which are cut a little different than the American setup. I use the Tamiya pro gears that are metric 64 pitch. The gearing is a little closer when you change pinions.

Run the 29T pinion. You won't be disappointed!

Hey psycho - should I run it with the RR 48 or 50? I tried it with the 50 and it was tight, very tight. That'll take me to 4:44 FGR with the 48 spur and 29T pinion. Also, I'm running the 540 motor.

I'm not sure what the RR 48 or 50 is. I run my TA03FS with the white 0.4 gears and the 29T pinion with a silver can 540 and it's among the fastest cars that I race with (silver can 540 race class.) It fits in without a problem and I have tested to make sure that larger pinions work using 64 pitch. I went as high as 32 since that was the biggest I had, but I can't ever imagine needing to run that low of gear ratio. I easily make the 8 minute runtime with 2400's too, so I could run with a larger pinion if needed. Hopefully that helps!

Hey Pyscho - that RR is for Robinson Racing, the spur adaptor that they sell for the TA03's. It comes with a 48 and a 50 spur.

With the 0.4 gears, what's the internal gear ratio? What's your FGR with that 29T

I'm actually not sure. Since it's so easy to change the internal ratio and some kits come with 15T pullies and others come with 16T pullies it's hard to find out what the true internal ratio actually is on the car. Mine came with both! I am running the 15T pullies and I believe the final ratio is around 5:1. I'm trying to keep my car TCS legal for the GT3 class so I don't have any non-Tamiya stuff on it. One thing I've found is that it is really hard to burn up a silver can motor, so you don't need to worry about overgearing too much.

I hear you.

I'm running at 4.44 with the Robinson Racing gears. I wont run these during a TCS event, I'll switch to either the black or white spur, 0.4 or 0.6.

Our track runs GT3 with the silver cans and the guys gear the 04's to the moon and back. No one is burning those things up. They some serious sized pinions on those cars. I think they run like a 42 or 43 tooth pinion and like the Tamiya 120 spur gear.

I want to try my 03R in that class but I think it is better suited to the GT2 class with stock motors where I can change brushes and springs to suit my car. It will be very hard to keep up with 04's in the GT3 class using those silver can motors unless you have an old silver motor that is tweakable and that is not TCS legal to my knowledge.

I would like to cut down my gears some like that Integy gear set from ahile back. The main diff gear is very narrow compared to the stock wide ones. Really cut down the friction on the car.

I don't have an older 540 motor, you shouldn't be able to tweak these motors but I know you can, what's the fun in that. If you have to cheat to win, you really didn't win.

It'll be interesting to see the 03's against the 04's in both GT3 and GT2.

Default TCS GT3 car

Not sure if this is the right area to ask this but I'm new to the tamiya scene and am interested to find out the best car to race in the GT3 class and any hop-ups I might need to make it competitive. Any help greatly appreciated.

jamnsmith-I think that WYD pointed out that the TA04's are better cars for the GT3 class. The 04's have a more efficient drive train than the 03's.

Psycho-Is the Tamiya 540 class at sheldons allowing double deck chassis like the DJ and TRF's or is it only tubs?
