The elipitical blade MT is 20 lbs lighter than the Hartzell. The scimitar
blade MT is also about 20 lbs lighter than the Hartzell. Same hub.

Additional comment,  Smoothness is awsome. the engine has flowed heads,
counterweighted crank, dual electronic ignition modified cam and reindexed
cam gear, Airflow performance forward sump fuel injection, high compression
10.5:1 pistons. I swear you can stand a quarter on edge on the airframe.  NO
VIBRATION WHATSOEVER.  AFter breakin we will add metered injection nozzels
for balanced fuel load although previous engine was pretty even in CYL
temps.

The scimitar blades emit that turboprop whirrrrring sound and it is quieter
than the eliptical blades which are also quieter than the two blade props.
The tips are squared off so you have max tip efficiency, less noise. 74 inch
diameter vs. 70. Also no RPM restrictions.

Ground runups at about 22-2,300 rpm just starts to skid the tires on the
tarmac at fine pitch. Does the same thing on a grass 17 degree incline
attitude at 2,400 rpm.  Hmmm should be a real animal.

Aero Composite Props also look interesting.

Today (Monday) is the day.  First flight in 18 months after engine failure
gear up on last 100 feet of runway. Will give you some numbers tonight. I
must admit that I am somewhat nervous getting back into the saddle.

Mel Hill of Portland, OR will do a first flight checkout then give me couple
hours of badly needed refresher training. Hope I can squeeze him into the
cockpit at 225lbs. Might have to remove the cushions for him.We will just
make gross weight.
