I made a few changes to the original Hummer. I was having issues with the wheels fouling on the body so I replaced the suspension with solid beams. It works perfectly and has some more height. I reduced the motor horsepower from 3500 to about 500. I added 2 rocket pods and 2 working cannons into the turret and added a hinge so that it rotates and also lifts the cannons up and down. Lastly I switched controls around. VTOL controls cannons angle, Trim spins the turret, throttle is throttle and steering is now yaw. The design of this H1 is awesome. Its got really great attention to detail, and it looks incredibly realistic. Full credit to the original designer, it probably looks a litte bit worse now as I had to strip the roof and turret down and rebuild it to make it work and it was really difficult on a phone.
