going to be going into a emaxx.

just wondering you think putting 8 cells to a 6xl motor would be to much lol.

I'm finishing my 3905 now with Twin Nemesis Blue 6XL's and 5S lipo's on it. I will let you know how it turns out....

ok cool. im thinking about just dong 2 6xls, 2 4 cell lipos, 2 mamba max esc

I would concider something with a higher amp handling capability- a forwards/brake only boat or plane esc would be cheaper, and some have rather good specs such as 200amps and 6s etc. Then again, if a bk9920 can do 5s with a 7xl, you might be fine.

The BK9920 will do 6S and with a Fan it should be fine on 5S...

Sweet Jesus.... that thing will be stupid-ugly powerful/fast. BE prepared to be constantly buying replacement parts.

Just imagine a top fuel dragster, and then imagine that... times 10.

I would actually consider putting two 8xl's in that, you will get the same topspeed (can pull higher gearing), and it will tame the beast on the acceleration aspect.... well, somewhat.

i kinda want to just run one motor (7xl or 6xl) the hv-110 esc by castle creations, and 8 cell lipos lol
