Hmm..... It's hard to say if going higher voltage is going to justify the huge increase in cost of controller.... For me, I happen to get high voltage controllers for a really good cost so it wasn't a big issue... I got a 32.40K that I'll use in my 10s emaxx for the future... controller only cost me 160 bucks... but it's only 40 amps continuous which should be fine cuz I'm not expecting it would even draw more than 40 amps. I have the 24.89 F controller that I got for only 260 which is a pretty good price too.

Either setup will give you MORE speed than you could use, but the 8s3500 will give you approx 40% more run time given the same speed. You can easily gear either setup to take you well beyond 50 mph.

I think if you were to bash, you'd get close to 30 minutes of runtime - and that's bashing around at high 20's mph with the occasional second gear run at 40 mph with 8s3500. With 6s3200, you should get around 20 minutes easily. Of course, it depends on gearing and driving style. I usually get bored after driving for 20 minutes straight.

BTW, I just ordered the 1200XL and if you hang on there, I'll test it with the 1200XL and 8s 3100 mah packs and I'll tell you speed and runtime. I do have 8s3500 also - but those dont' fit in the stock chassis.
