| BWD mantis chassis mod
Anyone ever tried to install swivel balls on the rear of their mantis chassis where the chassis bolts to the upper link mount. I think it could make the rear flex easier and smoother.

I thought the point to the Mantis was a stiff rear torsion axle.

i think it would still generally work the same, as I would simply be installing balls in the holes the bolt goes through which should remove slop and allow smooth movement.

I'll be watching to see how this turns out...ideally the chassis is "clamped" to the rear axle so the chassis can flex. That said, I'm really curious and happy to see you trying this Crazy enough, the Mantis is by far my most sold chassis kit even now. In fact, I have a few going out tomorrow, including one to Germany. Don |

Those ball ends are hot racing aluminum ones I was using the steel traxxas ones too. I used a rotory tool to grind the opening larger, not too large that it would be sloppy then I used the small die grinding bit that is a sphere shape to made the inside opening larger so the ball would snap in just like the rod ends do.

Be super careful bendi g the upper link mount like that you can put extra stress on the bearing/shaft in there and cause some skipping grindage and missing teeth.

I've wondered about doing this since I built mine up. How'd did it go?

Hey was just setting a chassis I just bought and was noticing the same thing on the rear upper links and was thinking maybe i was missing some pieces or that something like this should be done. I tried tightening everything down snug but it was really bending the link mounts in so i figured that wasnt the best either. I just threw out some ideas and questions to BWD so we will see what he has to say. Was thinking to add a insert int the mount holes so the threads of the bolt dont tear up the frame and add some washers to eat up some of the extra space to help keep the link mounts from bending when everything is good and tight. Have you been able to test on the swivel ball end installation yet? And how did it go?

Why not just cut the ends of the plates and place some rodends?

Use some washers and spacers to help..... you want it snug for sure. But try not to bent the link mounts.

Essentially you just eliminated a lot of the torsion on the rear of the chassis. Theoretically the way the chassis mounts in a fixed position is what allows it to have torsion between the 2 links. Now that it can pivot I would assume it has lost a lot of it's torsion? There is some torsion still provided between the 2 upper chassis mounts binding against each other.

Adding some of the cross bracing back into the chassis might give a happy medium of torsion with smoother pivot.
