Bottoming out B3...

[B3driver]

My Associated B3 has a habit of seriously bottoming out whenever I land from a jump. Specifically my rear chassis plate. My rear shock setup is

top link: middle

bottom: outside

I moved the bottom of the shocks to the inner hole just now. Will this help?

It will help. But cars, trucks, and buggys to bottom out is a natural thing. My GT bottoms out a lot. ALL the buggys and trucks at my track bottom out, the buggys especially hard because of a huge jump they case.

You must always push the limits. Because if you never fail, you will never succeed.

Cuss out the turn marshals because they cussed at you!!!

Crashing is an art of driving that goes bad in result in human or mechanical error.

Oh, its natural all right. But its hits a little hard.

Does it sound like something snaps when it lands from a jump? Like the chassis?

You may want to try a stiffer spring, and maybe a heavier oil. But this will also give you a bit more bounce over small bumps, so it's a trade off.

You could also try adjusting the ride height. Instead of having the dogbones parallel with the ground, have them angle down a bit toward the wheel.

If it's every jump, than you should probably adjust for it. If it's just one jump, I wouldn't make much change. Setup the car for best performance over the largest portion of the track.

Suspensions aren't meant to "eliminate" bottoming out. They absorb some shock when landing big jumps, and lessens the shock when it bottoms out. Try and drop an onroad and offroad car from 4 feet high. You can see that even though both bottom out, the shock inflicted on the onroad car will be significantly more than the offroad car.

Bottoming out on big jumps is normal.

JP. Its kinda a loud "CLAP" as it lands. I listened to another guys B3 and its not so bad. I'm using silver springs. Gonna try my new setup though.

You buggys normal.

Tay. Thnx.

you could run stiffer springs and or heavier shock oil... but that will affect you all the way around the track..... so if your B-3 is turning great, it might not after messing with your shocks so they won't bottem as hard......

all RC's bottem..... which is pretty pathetic considering how sensitive some of the electronics are that we carry onboard..... not only that, but evey time you bottem out, you scrub off a large amount of speed, and that certainly isn't the fastest way around a track.....

if you just want to help keep your rear shocks from botteming so hard do this..... use short pieces of fuel tubing placed on the shock shafts... make them just long enough that when the shocks compress and touch the tubing, that the rear of the buggy is about 1/8 inch off the ground.....
