What about this E-REVO design????

Here's another pic showing the tranny setup:

Seems OK to me. 8L seems a bit underpowered though, but since it still has first gear, it might be OK.

I would see if they have any plans/blueprints/specs so if some part of the custom chassis breaks, you can get another made or fabricate yourself.

Since it uses the two-speed tranny, you'll need to keep the mechanical brake and you won't have reverse. You can lock it into second gear to use motor brake and reverse, but then the 8L won't be powerful enough.
