I am currently scratch building a drag car here. Could I get some ideas,opinions on how long the wheelie bars need to be from the center line of the rear axle???  I am having an idea of them being like the 1 to 1 cars that are usually 60" inches long. I could just scale those down to size,but does that translate and work on these 1/24 cars on the track???

Some racing groups will limit their length, so it might be a good idea to check with local racers or the rules.the run by.

Rule of thumb is: If you have a 4.5 wheelbase, then 4.5 length to the wheelie bar wheels.

Of course if you go front wheel drive... no wheelie needed!  :wink3:

I tend to run mine at 4.5 to 5 inches.   5 inches is the max allowed in most Drag Racing rule sets.   If you look around Drag racing sites and blogs.  You will find a great majority run longer bars.  I don't see many cars running scale versions.

I'm certainly not an expert.  In my experience, the longer the better.  A longer bar allows for a finer adjustment of the height of the wheelie bar wheels, which I consider the most important adjustment on the car.  A longer bar also seems to make the car more stable and balanced when the chassis loads and unloads.  I find that my cars with longer bars are much less likely to experience wheel hop.  I set all mine right at 5" which is the maximum allowed by most tracks.  The fact that nearly all tracks set a max limit on bar length and nobody sets a minimum should tell us something.

That's really what slot cars with long wheelie bars are, aren't they?

5" max length since 1992.
FWD cars are best with max length wheelie bars. Have rear tires off the track. Wide soft front tires. Have run low 9's with a 16D at 120 grams for a class racer.
