What's a reasonable slip figure for a Ring 21, 17" setback, bullet of gearbox just above keel running a Raker II?
Also, if we're reaching our optimum rpm with a fresh out the box 24p Raker II is it possible to fiddle a 26p Raker II to get the same rpm? Blade thinning or reduced diameter? Any recommendations on who to trust prop work to?
Thanks
Paul
