it depends on what you are expecting for a 2M pattern plane. If you already fly a YS140 type of setup and have a lot of power then you will need more than what this spec says. The Hacker C50 is turning a 22x12 at 7000 rpm. I think you can figure that the power output is substantially different from the AXI. If you want to be competitive with glow, then you need a 2400 watt power system. You'll be at around 230 watts per pound to fly with as much authority as glow -- that's large Masters/FAI patterns.
