You're welcome over here any time Kev! - Hi Tony, BTW
Hmmm. Well batteries will always be an issue if you're going to use the standard E-Revo chassis / battery compartments. You might, ( Just! ) be able to get 8S in there if you used Revtech's Double Deuce LiPo's.
Don't know much about Plettenberg. When I researched them, they seemed overweight for the power and overpriced but a lot of people seem to love 'em.
Cheerz!
