Dan,
--There comes a point when weight vs horsepower becomes an issue. The I
O-720 weighs nearly 500 lbs installed. The Comanche 400 (IO-720) is a very
cool airplane but burns alot of gas for the weight. Roy Lopresti's Comanche
260 with clean-up mods could go just as fast. ---A P&W PT6-6 turbine
weighs just under 300 lbs and puts out over 600HP (not de-rated) The probl
em is cost. A good friend of mine actually removed his IO-540 from his F-1
in lieu of a 200HP flowed and balanced IO-360. Why?-Weight and handling.
He shaved over 160 lbs off his empty weight and only lost 8 knots at top en
d. Not that I'm removing my 540 anytime soon, I get to fly ALOT of RV's and
sometimes I too miss the light nose and empty weight of my 150HP wood prop
RV4.
-The advantage of a turbine for me would be the "less nose heavy ness" an
d ability to run diesel or kerosene.-

Not offhand, but I'll get the info for you.
The first one is being installed on, I think, a RV-7.

Hi Stan,
Do you happen to have a name or POC for the turbine presentation at
Chapter 288?
Although out of my price range right now, I'd like to keep up with what
they
are doing.
Thanks, Mark S.

Mark,
Found the info from EAA288.org web site.
PBS, Czech Republic built Turbo-Prop, TP-100 and the Turbo-Jet, TJ-100
Turbine Engines. The TJ-100 weighs 48 Lbs and generates 250 Lbs of thrust. If
you were at OSH, Air Venture 2010 you saw this engine powering an aerobatic
glider. The TP-100 develops 242 HP and is presently being installed in an
RV-10 by Diemech Turbines at their facility in Deland. Christian Skoppe is
President of Diemech Turbines and will attend the meeting. These Engines
have the potential to be a "Game Changer" in the light aircraft world.
