EK's Grand Canyon jump was only 200', so a mere scale 20 foot'r would do it! :D

Congrats on the 82mph! I would think that it should be technically be uncontrollable at about that speed. Point and pray.

The 1st have run is ok...but the front tires blow out when it gets going over 65mph...even if they are glued on...so at that point yes puckered tighter than a snare drum!

When you get her fine tuned bring her out to Idaho. The old Evel Knievel ramp is still there and the canyon is just begging to finally be conquered😎

It would be interesting if you changed nothing but put a cinder block a foot or so behind the car and see if your MPH improves.

My engine stuck out behind the car so I could place it right up against a solid object, yours is just inside the body so I worry about the blast ricocheting back inside your car.
