The warrior are the best high voltage controller for the money, but as the other posts indicate, the MGM controller has more programming options, including the ability to safeguard the LiPos and is smoother on takeoff(marginally). The warrior controllers only have a couple programmable features vs. many for the MGM controllers. I would bet the 9918 warrior could handle as much or more amps as the 120 amp MGM, though, simply because it has a heat sink. For 12 cells or less, the MGM is the winner IMHO, but for higher cell counts the warrior is the way to go.
