Flip the Zagi prop over and use it! Direct drive, you really don't want to get any larger than a 6x3 prop.

Be aware that your motor has been running backwards, and is broken in that way. Because of the way the brushes are now shaped, you won't get quite as much power out of it when you start running it "forwards" again.

What might be ideal is a Wattage "380" gearbox and a 9x6, 9x7, or 10x6 prop. The motor has to run backwards to make the propeller turn forwards, so you wouldn't be switching the way the motor turns.
