The effects of drive shaft angle

[MHeadling]

Just looking for some info on drive shaft angle and what effect it has on handling.

We are looking at the rear of a buggy.

What effect will a swept forward drive shaft have??

What effect with a straight drive shaft have (right angle to the chassis)??

What effect with a rearward swept drive shaft have??

I have checked out Elvo's tuning guide and couldn't see any info on this topic.

Drive shaft plunge is a term I'v read about with different types of driveshaft, UJ, CVD etc, but some info on this would be great too!
