bk6xl mgm120 on 4s lipo

[Gustav]

A pair of their 3s 3300 evo 20 is lighter and more powerful,and with an 8 or 9xl you won't need a controller able to handle all those amps from the hot 6 turn.Your origional plan makes much more sense to me.You said you want it light and fast,well then you need volts and all the cells in series.

Also 2 3s packs and a 9920 is cheaper than 2 4s packs and the MGM 160(which kicks into reverse every time you brake,lift off then brake,unless this is resolved now?)
