It would depend on the cells, but you should have a pretty good run time on that. Not sure how LONG though...Shayne might be able to help out as I know he runs 14 or 12 as well on a 7xl.

Yes, I run a 7xl on 14cells, but it is on a old set of gp 3300 nimh's, and i get maybe 10 min of run time...not real sure, but hte 7xl run's great on 14 cells.....it really seems to wake up on that # of cells....

all i need is bit better runtime than stock titans

hmm just found that 8XL is not in stock :(
