I'd say you need less anti squat and not more weight. It does not look like an easy climb though.

Maybe upper link mounting positions. Actually less anti squat. Looks like the truck has a bit stiff rea when climbing. My slingshot used to do that a lot even with increased weight and full droop rear. When I changed the rear shocks to 50-50 the truck became more forgiving in uphills.

Here is a pic of my homebrew 4 link. My front shocks, Traxxas emaxx are too stiff and I may have to modify the pistons to allow more fluid I am running Losi MRC soft springs and the Axial shocks in the rear are smooth. I think the rear is compensating for the fronts being too rigid. Does that make sense? Notice the bent lower link... It's been replaced with 8-32 rod with steel brake line. | |

I sat and watched some of your other vids. Looks like only the rear suspension does all the work in your rig. The front seems so stiff that I can't tell if it even cycles in the videos. When I said upper link mounting, I meant towards the chassis, sorry I did not clear that out. Check how parallel your links are, uppers compared to lowers. The closer together they are mounted on the chassis side the more anti squat you get. Increased anti squat generally made my truck feel bouncy and rigid on steep inclines. To get a general idea of how squat/anti squat comes into play you can make a small experiment. Place your rig on a flat surface unpowered. Hold the chassis, but not too firmly. Then try to rotate the rear axle front to back. Watch how the chassis reacts. This will school you on lots of adjustments that will help your truck. Now I have to state again that the climb you are trying is steep for a shafty and probably you will see minor improvement from these adjustments. Regards! |
