well go to the traxxas sight and search wheeli bars and on one this guy gave instructions on how to make one but this was a few months ago so... i just remember reading it... ill look and if i see it ill paste it here
here is how to make a wheelie bar your welcome...
These instructions are for a medium-duty wheelie bar. For heavy-duty, use 5/32 rod, 5/32 collars, and 1.25” wheels. Sorry if this is hard to understand, the diagram (see bottom of post) helps.
Materials I used:
- 10cm of 3/32 stainless steel rod = $0.08
- Great Planes 3/32 zinc-plated wheel collars (P# GPMQ4303) = $3.29
- Great Planes Nylon Nosegear blocks (P# GPMQ4263) = $1.99
- Great Planes 1” / 25mm Tailwheel (P# GPMQ4241) (two needed) = $1.79 each
Notes:
- The nosegear blocks I used are for 5/32 rod. The 3/32 blocks were too weak. The 5/32 block, however, will accommodate the 3/32 with very little play.
- Use zinc-plated collars and rod, as they will last longer than your truck.
- The nosegear block is white. You can dye/paint it, but if you have >1” wheels, you can easily place it on the inside of the skidplate for a cleaner appearance.
- The block includes all of the screws youÂ’ll need, and the collar kit includes a L-bent hex key.
- The wheels are not actually 3/32" as the package says. They need to be drilled out quite a bit to fit.
Directions:
First, put the nosegear block against the rear skidplate to make guide holes. If you want to restrict wheelies, place it low on the skid,; if you just want to have extreme wheelies, place it right below the bumper. DonÂ’t screw it on yet though.
Next, run the rod halfway into the block. Put a collar on the section that runs through the center for extra security, and then push the rod the rest of the way through. Make sure it is centered, and now out collars on both sides of the block. The supposedly "3/32" wheels are actually about 2/32. Get a drill bit with a diameter of (you guessed it) 3/32 and drill the wheels' center out. They're solid brass so it won't weaken them.
Put the wheels on, and secure them with collars on both sides.
If you want the truck to look cleaner, and have wheels larger than 1”, you can screw the assembly onto the inside of the skidplate. The wheels will still stick out enough to work. Unfortunately, if you bought 1” wheels (like me) forget it. The assembly will need to go on the outside.
When you accelerate, don't give it too much throttle once on the bar. This will cause the diff to unload and flip the truck. Accelerate with a bit more finesse, and you can still go mighty fast down the street.
