Thanks bud, youll really like the summit, it really depends on how you're driving it but if I had to guess i would say on average would probably be around 20 minutes
i have a summit normal size i bought the 15 minute batteries about 50 or 60 bucks you need 2 to drive and i get about 40 minutes on the 15 minute batteries
They're completely two different rc. The summit is a great all around rc. The xmaxx is a straight up a basher. But the summit can be a basher but It can crawl over anything you want it to. I have nitros to bash. The summit is my all time favorite rc.
