Group,

    There is a lot of chatter on the "Subaru" group about prop development

for the new "Eggenfellner" H6 engine with the 2.56 to 1 redrive (250+ hp

supercharged)........This engine and redrive is turning prop rpm's in the same

range as the Rotary with Tracy's RD1C 2.85 to 1 redrive.........Several of

the Subaru guys are using the "MT" prop but Eggenfellner has a new four

blade prop with "Quinti" hub,"Sensenich" hollow composite blades and

"Newsted" electronic controller that he hopes to have at 'Sun-N-Fun..........

 

   These are all electric props that can be flown as either inflight adjust or in

constant speed mode.........A lot of development is going on with props

for the alternate engine crowd.......

 

   A prop company called "Grand Aero" will also be at "Sun-N-Fun"........

They are developing a three blade electric prop that will use the so called

"ELLIPSE" blades designed by Paul Lipps and reported in several articles

in the past year.........The last I heard from them they were testing the new

hub for this prop with standard blades so I do not know current status of

the new blade design..........

 

   Just some things to check on at "Sun-N-Fun this year if you are there....
