Default I need your help...

Hi’ i’m planning to use the stock twin force chain+spur+pinion, then fix the chain pinion to the shaft of a 5:1 robbe reductor and motor. Will I loose a lot of torque removing the stock pinion and spur shaft (the one which the clutch)?
I will use six or more cells. What do you think about this setup?
I don’t know anything about this motor…

In my last crawler I have used the complete TF tranny with 5:1 reduction at the source, it climbed very well but it was too slow…

Another question is about the triangulation of the links. I will probably triangulate the lower inward at the chassis and the upper parallel. It’s a good solution? Or the best is to triangulate inward the upper at the axle and the lower parallel?

Thanks
bye

I don't know much about Twin Forces, so I can't help you there. However, I would recommend keeping your lower links parallel and your uppers triangulated inwards. Good luck.

Most people mount the bottom links straight, so that they can mount their shocks to them.

There is no difference made to articulation by which links you triangulate, it all depends on how much you triangulate them.

Triangulating one set also has to do with stability of the axles... If all your links were parallel, they'd swing back and forth under the chassis.... The triangle of the triangulation of the links prevents that from happeneing and keeps the axle where it's supposed to be...
