$10.000+ to go slower.....hmm. Something is wrong here. Bad blade
aerodynamics, perhaps?
Gary, if you cut one of the blades perpendicular to its axis, you'd
probably see something similar to a Clark Y airfoil. If you do this to
the Sensenich 76 EM prop, you'll see a Rose E (for Henry Rose, the
designer) airfoil. The Rose E is much more efficient. I know that MT is
working on more efficient airfoil sections, as evidenced by the new
scimitar blades being used on a Mooney conversion. Perhaps those will
be mated with the electric hub and approved for Grummans.
If that doesn't pan out, there is a chance that Aerocomposites will get
FAA approval on their composite props (www.aerocomposites.com).
Unfortunately, they don't have an electrically operated pitch
mechanism. It's going to require a complete engine mod to adapt the
Aerocomposite prop to a Grumman.

Dear Listers,
The phone company was out here bright and early this morning and repaired
the wires and the T1 connection is back up and rock solid!
Again my apologies for any inconvenience the disruption may have caused.
Best regards,
Matt Dralle
