Modified 2speed with aluminum screws, ceramic balls, titanium disc brake. It can still lose another six grams with tiR shaft and lightweight two speed housing, but these parts are impossible to find....

The ntc3 SG steel nut is probably 5grams. An aluminum version would have been much lighter(1.5grams or so)....Wow, I still got a good extra 8grams in my clutch....

I have now weighed all the drivetrain parts and found that my current lightweight parts are close enough to the lightest they can ever be in order not to really lose any significant power on the track....See you all at Wagner Rc Park.....

Have noticed two grooves being worn into clutchbell from clutch shoes, not sure if this is because of issue in final with screw or just because of the softer material than the original clutchbell.
In addition to the clutchbell you could run the new dynotech lightweight three shoe flywheel. It should be about a few grams less than the original three shoe non pullstart flywheel...That should have reduced the whole clutch assembly by 12


grams or so with the aluminum bell...

Dynotech racing makes an even lighter two shoe version that is only 4grams, and will also reduce the whole weight of the assembly by seven grams or so for a total clutch weight around 23grams...

Is OP still looking to race this car? Its been almost 10 years since this thread was started. I have seen some new TC3 kits floating around for sale if he wants to rebuild one, but for racing, I wouldn't say its a very competitive car compared to what's out there now and I used to race the TC3 back in the back as my backup car.

The OP had great success once he geared his tc3 with the dynotech racing 19t/25t with 54/48 spurs...Associated only had their cars way overgeared for .12 motors and racing on a standard track...Aim at 7.1fdr/4.8fdr and you will be competitive....Centax style clutches are around 40grams compared to 23g-29g for two shoe/three shoe clutches with aluminum endbells...
