Todd,
Will be very interested in the climb and speed changes that the high pitch blades give you..........Even though I have gone
to the dark side for now (Lycoming) in the hope of getting my project in the air in this life time I still hope to use a Rotary at
some point.........I have a "IVO" with (74"x30x90) blades and electric hub.........The flat area of the blades next to the hubs
has been blamed for blocking the cooling air and increasing drag which was holding top speed down.........I ventured an
opinion several years ago that covering the flat area with a larger spinner might negate much of this drag..........I suggested
that a 16 inch "Mustang Two" spinner would cover most of this flat area of the "IVO" hub.........
