Default Buggy Wheelies= Not Good

Ok so the question is, how do I stop my buggy from doing wheelies after the jump landing. Seems like when I make the big jumps or even some 2-3 footers the buggy will do a wheelie when I land and ride it till I let off for the turn. Am I getting on the throttle too hard too soon? I want to try and make as much speed as I can and beleive the longer you are in the air the slower you are. Do I need to look at my shock weights? I have 400F and 350R in a MBX5R. Im a new driver and not too familiar with handling characteristics or racing so any help would be greatly appreciated. Thanks

That's an easy fix. Let off the throttle and then ease back on it. If you have too much snap then lighten up a spring or 2.

Try going up in rear shock oil a little bit or maby even the next stiffer spring if not both. Also try a less agressive clutch setup. Like if you are useing 1.1mm springs try 1.0's or, I always liked carbons with 1.0s on that car was always nice and smooth engaging where aluminum's usualy engage quick. That is somewhere to start at least.

Also make sure you are using the right gearing. Check the specs for your car I am not sure exactly how many teeth are supposed to be on each of the gears in that car. Top end wise do you keep up with everyone else?

Just don't get on the throttle until you land. I don't know for sure, but it's probably not to good on the diffs either to be hammering the throttle as your landing.

7k in the center is too much for a buggy, go down to a 5k or even 4k, it will solve your issue.

making the back stiffer may cause more wheelies

Im not on the throttle when I land. Its the split second after I land is when I get back on it.

What about letting it land and roll for a few feet then get back on it? Also only happens when I land flat not on the backside transition.

flat landing could be the problem.... but going to lighter oil in the center could fix your issue or a lighter clutch spring as some else already suggested

He is at 350 in the rear which is very light for that car IMO giving him more rear traction and weight transfer to the rear.

more weight transfer will give more power to the front... rem. these cars have a center diff.. so the lighter the rear oil the more power is transfered to the front wheels.... and these diffs transfer power to the wheels with least resistants/ least traction.. making the rear stiffer will will give you less weight transfer and cause more power going to the rear and may cause more wheelies as a side effect... that being said ... his center diff maybe to stiff.. or is binding, causing it not to slip...

too much motor, too much clutch, too much traction, to much spring on shocks, too tall a gearing. try to soften the clutch springs, try a bigger clutchbell and maybe a smaller venturi on the carb if all your oils are within range for that car.

His front shocks are too stiff causing the front to bounce up
