What kind of mod are being done to get cars to 200mm? I currently have 4 TC that I would need to convert. Just not enough body options in 190mm.
Also how about 17.5 non timing motors or motors have to be set to 0 timing with blinky ESC? I would think more people would already have a 17.5 than have to go out and buy another motor.

You can use a wider hex, spacers, offset rims, or just run with a wider body.

The name of the 17.5 class was RCGT and it was sponsored by HPI. Very similar to USGT but running 17.5 motors on HPI X-pattern tires. Tire wear was a serious issue and speedwise the class wasn't much different from stock touring 17.5. The class has mostly died out for those reasons while USGT is picking up. If you want to race 17.5, then the 17.5 stock touring class would be a better choice for you than USGT.

+1 on what beemerfan said. use wheel hexes and off set wheels to get to 200mm. Honestly though you can't really tell a difference if a 200mm body is on a 190mm chassis. its only 5mm per side and the wider body may actually protect the a arms and c hubs better. You would probably be better off using wheel base and track width as a tuning option instead of trying to fit a body size.

17.5 is already being run in the tc class and honestly its a little too fast for a lot of people. plus there is not a lot of selection for tc legal bodies. the 21.5 is a great wind offering great torque, good rpm, and great durability. You don't have to work it hard to have a quick car. it really fits the usgt class nicely. A lot of people already have the 21.5 too. it was used for vta a while back and it is also used in f1. I would strongly suggest using the 21.5 and the rest of the usgt rule set but if your club overwhelmingly wants to use 17.5 then go for it but attending regional or national events would be a huge change for your racers. Give the 21.5 a shot. you will probably like it.

I race at Prolevelrc, Drew Ellis's track. We run TC and 1/12 but I would like to run something other than TC. With me and my kids there are 4 TC so we can make up our own class. I was looking for options and not have to go and buy 4 new motors, but I understand where everyone is coming from. I just don't really care for TC bodies. I want to race cars that replicate REAL race cars. I come from a background in the SCCA and have been around racing all my life (I just can't afford to do the full scale cars, ). Thought about the USVTA also but that too involves all new speedos, motors, and tires which gets $$ when you have to convert 4 cars. I also race 1/12 with one of my other kids so as you can see from my signature there is a lot of us. Thanks for all the comments. Keep them coming.

Here are some different Losi hex adapters that can be used on the TC3/TC4, or Losi XXX-S/JRSX cars that come in different widths (http://www.horizonhobby.com/webapp/w...pe=productgrid)

Not sure how well they would work on cars with smaller axle diameters like the TC5 or Xrays.

-----------

The best way to change wheel base is by using different offset wheels. Using spacers or larger hex adapters to make the car wider can reduce the amount of threads available on the axle to secure the wheel nut to the axle. This can result in loose wheel nuts, which are more prone to falling off during racing.

One thing to be aware of with offset wheels is that it can be harder to get a wrench into the recessed area of the wheel to secure the nut. This isn't usually an issue with cars that use smaller wheel nuts (Tamiya, TC5/6, Xray). However with cars like the TC3/4 and some Losi 1/10 TC you may have a problem.

If using a TC3/4 with offset wheels, you may have to modify the outside diameter of your wheel wrench.

While you can widen the car to match the body, it's not really necessary. i have run a lot of 200mm bodies with the car at 190 or less. You don't notice it too much.

It is the kick up in the back, it has to be cut down to 10mm and the rules my club uses 15mm on the up side of the side damms.

I imagine this what the wing rule was supposed to refer too but it is not wing chord. Wing chord is the distance from the leading edge of the wing to the trailing edge.

Maybe Rob k can clear up any confusion on what the rule means.

That would be a real skinny wing!
