The plan is to use the original prop assembly that can jettison. The only thing I am not sure of is will I have cavitation problems. The prop will be about 12 inches from the occupant sphere, mounted in the centre of the sphere (equator) </div><div>Will I have to put a spacer between the sphere and prop assembly to move it further away?</div><div>Hank</div><div><br></div><div><br></div></div></body></html>
