I am using a crew cab truck body.

Our main thing we didn't want was people to use high downforce/touring car bodies for the crawler class.

Truck, Jeep, FJ, ect you'll be good to go.

not an official here, but i cant see how a tuber would act as a high downforce body. id think a tuber would be ok.

i think a tuber within 2.2 USRCCA specs would be fine.

i have some ideas for keeping the wheels on the ground and this shootout has resparked intrest in my kit. (havent touched it since jan)
Sorry for the delay in replying. The rear wing down force doesn't kick in till the car gets to about 50 mph. If you are popping wheelies after that point yes, you will need a wheelie bar. If you are popping wheelies from start line to until the rear wing kicks in, that's due to a combination effect of motor torque and low weight/weight distribution (40F/60R is a good starting point for a 24" car) which absolutely requires a wheelie bar. I am not saying what I "think" to be true, this is what happens at a RC drag race with high traction.

You are spot on that you will have to be very careful with the throttle when you do speed runs. A wheelie bar just makes it more forgiving.

Do you want us to put any and all video on our build threads or in the video section?

Just saw this last night on accident. Got my mind spinning last night and started searching for parts. Is it too late to start a thread and enter? I have a vision for a crawler class entry.

Why are most of the builds 2wd? I don't see anything in the rules about not running a 4wd sedan, or did I miss it?

nope, however drivetrain efficiency plays a big part in top speed. a 2wd car, such as the drag race designed chassis use the most efficient drivetrain you can have in an rc. 4wd is great for handling and racing, however if you can get straight line traction with 2wd, why have 4wd???

You answered the question yourself, because a 4wd sedan would be much easier to drive to higher speeds, and in a shorter distance. 2wd on an unprepared surface is squirrely at best.
