insane BL-setup for a b4 ?

[speedy]

HI !

if i whant topspeed over 60mph with a b4 choud i get a mambamax 5700kv on 3s or a 7700kv on 2s ? and how long runtimes can i expect with a maxamps4000 or 8000mah lipo pack? and what about 6st ib3800 cells ?

Don't know what the runtimes would be like, but my first choice for 60mph would be 5700 and maxamps 3s 4000 or 6000. Guess would be at least 15 minutes hard running with 4000mah... 20-30min for bashing?

WOW ! that long ? that amazing!!:004:
so with 6000mah like 40-50min off runtime if i don't pegg the thottle all the time ? he he ! that woud be difficult to do at 60mph+ :005:
