That 1350 will definitely need 6s to be responsive! On 6s, thats still only 29970 rpms, which is pretty conservative! You could run that motor on 8s no problems!

And Nimh packs just dont cut it either.

Swapping in that 2250 motor will really wake it up tho! But gear conservatively with those NimH packs otherwise, you'll fry those packs in no time from the massive amp draws. Or use the Lipo's you have and hold on!
