Jim,
Nice looking engine for the Zero. What size prop are you planning on using? I am planning on using a Brillelli 46GT with a Bambula 20x10 prop. I have a XYZ-50 in a Skyshark P-40 that spins that same prop at 6950 RPM. The Brillelli 46GT engine I fell is a little stronger than the XYZ-50 so it should have plenty of power for the Zero.
