Setup changes that can affect jumping
 

Hello all I'm having problems with the attitude of my truck while jumping and was wondering what things I might change to fix it. Most of the time I think it's nosediving to much other and im giving it throttle so it doesn't go nose first right into the track. Other times it's nosehigh. I'm not a rookie and have no issues with my 2wd or 4wd buggies.

How much drag brake do you have ?

If it is a 4wd SC, it will have enough drag in the drivetrain to where you either have to use “push control”, or use the throttle to ensure the wheels keep momentum (gyro) going forward. Otherwise as soon as you go to neutral on the throttle the truck is going to drop the front end like a rock. 4wd SC trucks have a glide factor of ZERO.

0 and it's a stadium truck

Anti-squat, weight distribution, and pretty much any aspect of the shock package.

Does the truck do this over every jump, or just one jump?

Are you running on carpet with harsh wood ramps?

If the rear of your truck bottoms out coming up a jump, it will kick the truck nose down as it leaves the ground. If it does this off every jump you probably need to make a suspension adjustment or two. If it is only on one jump, maybe adjust how you hit the one jump. Maybe approach the jump a little slower, and accelerate off the jump more.

What setup are you running? What model stadium truck do you have?

Make sure you are not running so much droop it is binding the dogbones when the truck is in the air. If they are binding up it will be just like slamming on brakes in the air. Also make sure the rear end is not chassis slapping the face as others have mentioned. Go up on oil and/or stiffer spring if it is.

I'm running on carpet with hard wood jumps. I asked one of the fast guys at my track and he said I needed to put my rear wing on and until I do that it won't work right. They changed the layout on the track and tonight it was running much better then the old layout.

Thanks I'll take good look at it.
