I would consider myself the be one of the better locals in off road in my area. I know the main difference is belt vs shaft. Is the 5 that much better?
You don't want to be racing the TC3 on any track with boards, you will break it in a heartbeat. For Rubber racing, the TC5 will be at home, for carpet foam racing, beware of the cars weaknesses. I will briefly go over a few things about the TC5, other may chime in too about their cars.
The C-HUBS are not very durable. When you hit a board, clinch-up. When they break, they almost always break where the bottom screw goes through to the steering knuckle. I broke probably 5 in the 4-months I drove the TC5, and all broke in the same spot. Buy several extra pairs when you order/buy the TC5, you will need them.
Get some 8mm and 10mm long ball studs, this kit most uses 5mm long ball studs. They have black and silver ball studs. The silver ball studs are taller, requiring less spacers when adjusting your setup. You will want to use the longer ball studs so the threads are fully engaged in the Steering Knuckles and Rear Uprights, ecspecially when using spacers to change roll-center or bumpsteer.
Wheel Bearings is another bad spot on the TC5. AE's choice of using 6x10x3mm wheel bearings was not too thought out in the testing phases. These narrow bearings are so small that they just can handle much abuse for long. I'm sure AE chose a smaller wheel bearing for reduced drag and weight, but at the cost of longevity wasn't practical. So far I've only found one other TC that uses 6x10's for wheel bearings, the Yokomo MR4TC. I recommend you go over to www.avidrc.com
and get an extra 20 or so 6x10x3mm Revolutions bearings now, you will need them over several months of racing. Don't waste your money on ceramic wheel bearings in this car, you will toast them too quick, but ceramics in the rest of the drive-train will help free up belt tightness issue.
As with almost all Touring Cars, buy some extra plastic outdrives. If you are going to get the aluminum outdrives and spool or one-way, get about x32 bone blades for your axles when using the Al outdrives. These will bearing out and fall off, causing your axles to eat the Al outdrives.
