Do you hit the brakes while in the air? Basic rule of thumb, hit the throttle...front comes up. Hit the brakes front comes down. You might be hitting the jump wrong also. Make sure there isn't a lip on the jump that is making your back wheels get caught on and sending it into the death rolls. Anyone else agree that's why, or could be why? Thats just my $0.02.
I dont have any brakes. the company sent me the wrong linkages so I had to cut the brake linkage to use the throttle. when I get home I will try to stay on the throttle. I dont hit it in the air, so that might be my problem.
