I rigged up a front wing setup to try to keep the front end down. Even with the wheely bar it likes to carry the front wheels an inch or two off the ground.
This pic shows the HPI spur, and the limiting chains I made to keep the rear suspension in shape when the wheely bar tries to make the rear wheels leave the ground.
I still havent strapped the GPS to it because I keep breaking parts very early in my runs. This past time it was the steering bellcrank because of a wheelie induced cartwheel. It also tends to wreck violently, so Im worried about what it would do to the GPS. According to the speed calculator its good for 70ish.
