    I have an HKS-700e. In my opinion, You're going to need a gear or belt reduction to have a shot at flight. I'd also look for 70+ inches of prop length. I think a ratio of 2.3 to 1 is in the ballpark. that would allow the engine to run at 5600 RPM for high output power and the prop to turn at ~2400 rpm. with a 72 or 74 inch prop you should get good thrust.

    post a pic of your gyro, mine is very very light and may not be a good choice to emulate.
