Default Rear suspension question.

I run my B5m at a local carpet track. There are a number of jumps and the buggy performs well all around. Except in a section where there are two small whoop style bumps(inch and a half maybe two inch bumps) , if try and speed through there my buggys rear kicks up and over the front end so there I am relying on a Marshall to flip me over. What would help me here? Here is a video the section I am talking about is 11 seconds into the video (that's not me driving) you can see this guy's buggy rear end kicking up, mine is more dramatic. Any help appreciated

Keep in mind my buggy jumps like a dream everywhere else on the track. New to racing. Shocks stiffer/softer in the rear? Oil weight thicker/thinner? I am not running with any drag brake.

The rear is packing up under high wheel rates. If you are running the 3x1.4 pistons try switching to the 2x1.7.

I'd say you need to soften the rear oil or change pistons.

I'll try this. This would slow the dampening speed am I right?

Wouldn't that make it bottom out quicker causing the rear end to hit the ground and bump it up and over? Or am I thinking about it the wrong way?

Depends why it is kicking. I couldn't find the video with the link you posted, but typically a bucking car is either caused by the chassis hitting because the suspension is too soft or the shocks packing up because they are too stiff. Without seeing the video, it's hard to tell which side of the equation is giving you the result.

Thanks for the replies. https://www.facebook.com/story.phpstory_fbid=1760952740813944&id=1709884492 587436

Link should work. It was previously setup for mobile.

The video isn't working since it is embedded in Facebook. You need the direct link.

But if the chassis is bottoming out causing it to bounce off the bump, you may need to slow the rear suspension down. Thicker oil.

If it is popping off the bump due to the rear suspension not keeping up, you need to speed it up a bit. Thinner oil or different piston.

Guys my B5M lite stalls after a few laps especially landing hard on a jump and bottoming out. I took out the fan on my motor and the problem went away. Does anybody had any problem similar to my experience. Really need the fan to keep the motor temp down. Is it the reciever that I am using? I run the stock telemetry receiver that came with the Futaba 4PLS radio system the Futaba R304SB Receiver and the LRP Flow Works team ESC.

Have any of you gone back to the original b5m setup? Gullwing arms and b5m rear arms?
I may try it Wednesday to see how I like it.

I would contact LRP and change the speed controller.

Default Diff outdrive

Anybody knows if someone sells a more heavy duty diff outdrives. Mine got chewed up by the dogbone pins. And is there a dogbone or cvd/cva that has the pins going into the outdrive REMOVABLE or REPLACEABLE? I remember MIP had those for the RC10GT ... They we're called CVDs back then.
