So here is one of the two entries that I am entering in this weekend's GSL Championship in Salt Lake City. It is being entered into the "Replica" class, as this is a model of the off-road race car that I used to own. I was the owner, driver, chief mechanic and sole sponsor. Needless to say, this was time consuming. Class 9 is the "Formula Vee" of off-road racing. The class rules are very restrictive, and it is meant to be a driver's class, and affordable racing. The cars use many standard VW components, and modifications are very limited.

The model is mostly scratch built, with the chassis made from brass rod. It has a few basic parts for the Tamiya VW kit, but they are also highly modified. There are some turned aluminum parts (Fox shocks), but most of the fabricated details are plastic.

So here is a photo of the real car:

Here are a few photos of the model:

I made a second chassis for "show and tell". It usually draws a lot of attention. The wood master is for the vac-formed hood. It is hand made, and represents the inside of part surface. The hood was then cut out of the formed part.

Here is the engine area, fully detailed and plumbed. Exhaust was made from brass rod, in a fixture that I fabricated. The chassis also has a removable spare tire rack. I used this for longer races, but for shorter ones, where there was crew access, I left it off.

Anyway, it should be fun to show it at GSL.

Thanks everyone for the kind words. The model was much easier to build when I had the real one just sitting besides the work bench. If I wondered what size something was, I just went over and measured!

The real one was fun to drive, but naturally underpowered. Required was basically a 40 HP, single port head motor, but with the cam wide open. The small carb was required, but could be re-jetted. Not sure where the HP ended up, but with the light weight, it did well. The suspension mods were limited, so with it's limited vertical wheel travel, it rode hard in the woops.

I finally sold it when they stopped racing locally here in Central Oregon. I tried a race clear down in Fallon, Nevada (near Reno), and it was just to far to go. I at least sold it for what I paid for it, so that was good.

What a cool build! That is a real rarity and your perfect rendering of the real thing is beautiful and an important bit of history. Thanks for sharing great fotos. You should do a tutorial here on building brass frames and connecting plastic parts, engines etc without having it look phony. Superior craftsmanship all 'round!
