Default Tamiya Tamtech Gear Thread

Lets get some discussion going. Who's got one? What mods have you done? Lets see some pics. I just ordered the bumper set, and I have some Tamiya oil shocks on the way.

Here are a few shots with my new HPI kicks. Much more suited to parking lot duty.

Good thread, but I'm kind of surprised there doesn't seem to be much TamTech interest in this forum. I love the old school Tamiya buggy looks so I thought these little ones would be more popular.

Those meats on the Frog look pretty good. Where did you order the Tamiya oil shocks from? I wish they made yellow oil shocks.

I have a Frog and was thinking of putting in the RX-280 motor from the Losi Mini Baja, its pretty quick, will that work? The stock Frog motor is pretty slow. What are you running in your TamTechs?

I can't wait to get a Buggy Champ (Rough Rider). It looks like a real dune buggy and they made the front suspension like the original old school Rough Rider.

Yeah I thought they would be more popular too. I ordered them from ebay. I cant remember the sellers ID right now. I will check later and post it here for you. I had originally ordered them from another member and they never showed up so I had to get a refund and re-order them from another seller. I agree that they should have made some yellow oil shocks. I am thinking about ordering another CVA damper set and using the internals to try and modify the yellow shocks to be oil dampers. I'll let you know how that works out.

I love the looks of the Buggy Champ I can't wait til it's available. I will probably pick one of those up too. I am just running the Sport Tuned motor at the moment. It is quite a bit better than the stocker but still not fast by any means. The holes in the motor mount plate would have to be modded slightly to bolt any of the 280 motors up, but the Orion Baja is a direct fit, and it works very well in these buggies. That is next on my list of hop ups. I used to have one in one of my Mini-Ts and it is a fantastic motor, I wish I would have kept that when I sold the T. A few people at my LHS are running them in their Tamtechs though and with a 16 tooth pinion it is plenty fast enough to be very fun.

Good tip on the Orion motor. I see Tamiya just came out with an upgraded SS motor which is supposed to be better than the original sport tuned. I may try this new one first because it's only 12 bucks compared to the Orion. But you need to use aluminum pinions with the newer Tamiya motor I see.

The new SPT motor is much better than the original sport tuned. It is about a third again faster with even better torque. You can easily gear the SPT with an 18 tooth pinion for decent top speed, and not lose much acceleration.

Also, just so you know the AE and Robinson Racing pinions for the RC18 series vehicles work perfect, and last alot longer than the Tamiya aluminum ones.

I am not sure where you can find any info online. I have played with these motors on a dyno a little bit though and @ 7.2v the original sport tuned turns about 23,500 RPM. The newer SPT version with the red endbell produces a significantly higher amount of torque and turns right around 27,000 RPM @ 7.2v so the SPT version is well worth the extra couple dollars. I hope this helps.

thank you very much, that's all i need actually since i dont think it will pull more amps than 540 sport tuned significantly. i am actually a bit surprised that it turns up to 23k rpm, but thats very good, perfect for my application. i will ask my LHS if they have the newer version.

You're welcome. I was a little surprised at the results myself. I would have guessed about 18,000 for the original and 21-22 for the SPT but it seems they are a little better than I had anticipated. Always a welcome surprise.

It should pull considerably less current than the sport tuned 540, I haven't done any current draw testing on the 540 version but I would think it would pull almost double what the 370 version does.

I just finished mounting a set of the lights from the Frog and Hornet bodies on my Fox body. Just a little something extra to make it stand out in a crowd.

Nice tip. I see Robinson has 32 pitch gears, I will pick up a few of those for my 1/10 Frog and Brat too. Dumb question: what pitch gears do I want for the TT? I forget what tooth count pinion is stock on TT Frog too.

Your lights look good.

Thanks. I am not sure what tooth pinion is stock on the Frog, stock for the Fox is 16T, I am pretty sure they are 48p gears but if you do a tower search for RC18T pinion it will bring the Robinson and AE gears up. They both work well but I like the Robinson gears better.

Have you tried ebay? That or tamiyaclub.com will probably be your best bet.

I would assume the TT uses 48P metric, but the RR pinions in that pitch are 3.2mm

You're right, but Robinson makes 48p gears for the RC18 series that are 2mm and they work perfect for the TT buggies.

My brother in law is picking up a TT Hornet and a few hop ups tomorrow at the LHS, and then it's off to the off road carpet track for some head to head TCS rules racing. We are planning on attending at least one TCS event this year but hopefully we can make it to a few more than that. I'll post results and a few pics sunday. GO FOX!!

We will be running the Tamiya sport tuned motor and any Tamiya option parts. Any brand of oil shock is allowed, but Tamiya wheels must be used with the drivers choice of tires. Rear wheels and tires will not be allowed on the front, and only 6 cell nicd or nimh batteries will be allowed. It should make for some close exciting racing. I can't wait.

Aluminum oil shocks are here. I will install them and get some pics up asap. Now hopefully the man in brown brings my motor and I will be ready to go for tomorrow.
