   Hope they can pull this off. Sportcopter is located near my hanger in
   Scappoose and I have see the gyrocopter. Haven't seen it fly yet,
   though.

   -------------------
   These are the specs of the Gyro your talking about,
   I'm not sure where the Rotomax engine comes in as it specifically states
   a Subaru engine.

   Fuselage Length: 175" ( 14.5')
   Cabin Inside Dimensions 49"
   Height: 10'
   Width: 83"
   Rotor Diameter: 30-32'
   Engine: 190 hp Subaru (Turbo opt.)
   Fuel: 87 Octane Auto Gas
   Fuel Consumption: 6-8 gph
   Fuel Capacity: 30 gal.
   Dry Weight: N/A
   Useful Load: 500-600 lbs.
   Gross Weight N/A

   Could someone elaborate on this please.


   Regards David


   I don't believe these fuel burn numbers.
   Somebody is lying. 190 HP at .45 BSFC is 14 gallons an hour.
   If by some miracle they got the BSFC down to .4 BSFC the burn would
   be 12.6 GPH.

   Eight gallons an hour will give you about 108 HP which is about
   right for a Subaru.
   Six gallons an hour will give you about 80 HP.

   I just drove a brand new Subaru Forester over in Phoenix and it was
   a dog on acceleration
   and gas mileage. Nothing even close to 190 HP. I was surprised. I
   guess it is the four wheel
   drive that slows it down and sucks the fuel.

   Paul,

   I think they would typically advertise a cruise RPM fuel consumption..
   Kinda like they say a 182 runs on 12gph even though it has 230hp. 60%
   power or so.

   A rental would probably have had the base 173hp non-turbo engine and the
   cheaper 4 speed auto tranny. What mileage did you get? They advertise
   mid-20's for mixed driving. Is that a total joke?

   The apparent speed of a car depends on whether it makes nice noises or
   not.. 'Course you knew that. :)


   Matt-

   I did not measure the mileage. I was just going on what other
   economy cars get like Chevy's and my Honda van.

   They must be cruising it at 108/190 or 55% power.

The specs you have here are for a Subaru.  The SportCopter Super Sport
gyroplane is flying in Scapoose OR currently with a Subaru engine
installed.  We are shipping a twin rotor RAE engine from Rotamax to them
in the next week (the engine is here w/me right now, just boxing it up)
and it will then be installed there in preparation for flight testing.

You can see some video of the SportCopter Super Sport flying here:

and here: http://www.youtube.com/watch?v=CDK2yGce1Wg

I will let you know what the fuel burn is on the gyroplane when it flies
w/the RAE engine from Rotamax

Nate, We can do  firewall forward design including cooling layout for either
the Sport Copter or the OutBack. No charge. Jerry Hey is willing to build motor
mounts. Charge. All we need are a few dimensions.
