Not my USVTA bumper or body =

But same principle =

I used a U.S. Vintage Trans-Am Racing Part 2-dscn4600.jpg

To cut my U.S. Vintage Trans-Am Racing Part 2-dscn4602.jpgU.S. Vintage Trans-Am Racing Part 2-dscn4603.jpg

And two side servo tape to hold the two separate bumpers together

But my car isn't a TC4

So my method might not work for you...

I have a virtually idiot-proof way for making the post holes in the foam block...

Yes, the FDR limit keeps the speeds down, that is the point.

Yes, some motors are faster than others. Same car, same setup, same FDR and with motor A the lap times were 8.45 seconds. Change the motor and the laptimes went to 9.2 seconds. Having no gear limit or timing limit allows the racers to speed up their cars to be competitive.

Yes, the fast guy will always be fast, they are good drivers. This just allows us to give the Fast drivers with a crappy motor a chance to keep up rather than have to reach into his pocket and gamble with a new motor.

We choose to limit the speeds to keep it close and fun. I'm done talking about our local rule and how it benefits us. I am not trying to get the national rules changed. Come to our track and see what 7 cars all going the same speed in a 4 foot lane it like! It is indeed like a boxing match!

Yeah, saw that this afternoon. For now, the RPM of the wheels is working great...and a lot easier too.

The TC3 can run the RPM bumper which is what I'm using. Its a wonderful thing for me and my occasional Kamakazi behavior. Do these also fit the TC4's?

If you are running a TC4 (and possibly the TC5), you can use an RPM NTC3 plastic bumper at the front of your car. You will need to use the stock bumper AND the RPM bumper. You will also want to buy Assoc. part #2232 (rubber bushings) to help secure the bumper.

Here is a link on RPM's website
http://www.rpmrcproducts.com/products/assoc/chassis.htm

Here is a picture of the bumper


As far as better/wider than OEM foam bumpers, Parma PSE makes foam bumpers for several different typs of touring cars. Here is a link.
http://parmapse.shptron.com/c/rc-car..._front-bumpers

If they don't sell a bumper for a specific car (or is discontinued like their TC4 bumper), they do sell a rectangular bumper which can be cut to fit. Here is a picture of the generic foam bumper:


Lastly, if you just are wanting to fill the gap between your current bumper & VTA body, you can also use HPI part #6273. These are self-adhesive foam bumper strips. Here is a link to this product:
http://www.hpiracing.com/products/en/6273/

Another common topic on the thread is how to reinforce an R/C car body and/or how to secure parts of a 2-piece body. Here are a few products that can be readily found at most big box hardwares stores or large retail outlets (Wal-mart, Target, etc)

Shoe Goo (http://www.eclecticproducts.com/shoegoo.htm)

Shoe Goo is great for the front end of a car because it will flex when full cured. The only drawback to using Shoe Goo is that it can take several hours to set and over 24 hours to fully cure. Not the best solution for race day repairs.
---------

Liquid Nails (http://www.liquidnails.com/products/green-glue-LN207)

Liquid Nails is a similar product to Shoe Goo, except when fully dried/cured it seemed to be a bit more rigid. I've used this product on the HPI 'Cuda at the seam of the hood/quarter panels and it has helped prevent the front end from drooping due to contact with other objects (translated: poor driving).
----------

Fibreglass Mesh Tape (commonly called drywall mesh tape or drywall joint tape). (http://www.homedepot.com/webapp/cata...gry=Search+All)

Most people use the tape to help reinforce areas of the car that are prone to breaking or falling off (the nose or 2-piece body parts). They will place the tape in the area prone to damage and then cover it with Shoe Goo (or similar). Look for the tape that is self-adhesive as it makes it easier to use.
---------

Nylon screws/nuts (http://www3.towerhobbies.com/cgi-bin...?&I=LXPM80&P=7)

I have used nylon screws to secure the rear 2-piece section on HPI bodies that have a separate rear bumper piece. I usually put a screw in the section where the rear bumper piece secures to the rear quarter panels. While it may not be the most visually appealing solution, it is light weight and helps prevent the rear of the body falling out due to contact (or poor driving).
----------

Of course any of the solutions will add weight to your car and should be applied as sparingly as possible. Also silcone glues (and even double-sided tape) can react with paint. It is best to let your new paint job cure for several days before you apply any adhesive to the inside of your body.

Sorry for hijacking the thread with my latest posts. Hopefully I have provided some useful info.

I use gauze pads instead of the fibreglass tape. Just open one up and cut it into strips or use the kind that comes on a roll. It gives the shoe goo some structure to help it hold it's shape. Lets you use less shoe goo for the same result.

Thanks for posting about the guaze pads. I was wondering if there was a readily available cheap material that could be used instead of the dryway tape.

-----------

In response to below, gauze has a tighter weave and might prove to be stronger. Also you might be able to scavenge the pad in a large adhesive bandage if you have one laying around (technically free, right?)

Also I tend to injury myself when working on my rc car, so the guaze might save my life

I dont know about where you live, but a roll of drywall tape was like $3 at Lowe's here. Gauze costs more than that
