    i noticed when watching the pros their cars do not slap even on a flat landing? i have been messing with oils and pistons but cant seem to get rid of it. the stock setup is too light for my track. i run on an indoor track with big doubles. i tried the #3 pistons but it wasnt consistent around the track. i like the way #2 pistons feel but bottoms out too easy. right now im at 35wt in the rear. green springs.

    1/10 scale, some jumps on local tracks are slappers.

    1/8 scale many jumps are slappers. What I see, locally, mostly with 1/8 is they drag on the up ramp

    Pro tracks, that have worlds or national level races can be raced in either direction so there not much slap-able jumps.

    Last week WCRC had the ROAR off road nationals. They raced one direction for buggies and trucks, then the other way for sc and 1/8 scale.

    Learning how to "down side a jump" stops a lot of slapping.

    "down side a jump" <<<< landing on the down slope of a jump instead of landing at the bottom or after a jump.

    Find a pro setup for your rc that fits your track, to start with. One of the best resource for setup sheet is Petit RC in France.

    What is your ride height? Maybe add a MM to the rear end to help?
