    replied to Rotor Blade Length
    In my opinion you are calculating the disk loading rather than the blade loading.

    For The Predator with her 30 foot blades the disk loading is about 1.98

    I feel the blade loading is calculated by taking the area of the blades and dividing it into the gross weight. For The...

    replied to Rotor blade rpm which is best
    In my opinion Eddie if I am going to fly airshows I like a fast blade so I have more of a margin for low G maneuvers and can tolerate higher indicated air speeds better.

    In theory slower uses less power but the European gyroplanes seem pretty efficient.

    I have trouble nursing...

  • I like that the new format has a like button.

    I like the photo size options.

    I like the way it remembers what you were going to write when you go off somewhere else.

    What sort of trouble are you asking about?

    Glad to fill in your blanks Chris.

    replied to Low and Slow, what to do?
    I agree Brent.

    If I am practicing recovery from low air speed I do it at 1,500 feet above the ground.

    I had an engine out practicing vertical descents with a CFI on board and we were both glad to have some altitude to give us more choices of a landing zone in the muddy fields....

    replied to Low and Slow, what to do?
    The gyroplane we were flying (The Predator) in near centerline thrust so adding power at low airspeed as he lowered the nose would work fine Javier.

    In my opinion with a high thrust line gyroplane at low speeds it is best not to go to full power because the horizontal stabilizer is not...

    started a topic Low and Slow, what to do?

    Low and Slow, what to do?

    I recently had what I felt was a valuable learning experience. I had a low time client get both low (350íAGL) and slow (27kts) on down wind.

    He was not comfortable lowering the nose to pick up airspeed because we were already low and he felt correctly we would lose more altitude so he...

    replied to P740 engine for gyroplane
    Welcome to the Rotary Wing Forum Christos.

    The last post on this thread is from 10/2014 and I havenít seen anything since.

    I suspect that indicates that the engine didnít work out.

    People are always trying to find something less expensive than...

    Welcome to the Rotary Wing Forum Jack!

    I hope you will do what it takes to get good training Jack.

    A gyroplane does not fly like anything else and if you are a pilot of anything else your first response may be incorrect for a gyroplane.

    I donít know any Certificated...

  • She had a 914 in her and we were near gross.

    She flew slightly nose down because she was set up for much lighter people.

    I am always amazed at how nicely a Dominator flies.

    I could not see the instruments and had to ask Ernie for the airspeed and altitude.

    replied to What Type of Rotor Blade?
    There are not a lot of choices for a 1,400 pound gross weight gyroplane Jerry.
    I had composite RAF blades on The Predator and they were cracking on the trailing edge.
    I purchased Sport Copter blades and they have held up well and seem to perform well.
    They are fabricated aluminum....

    replied to What Type of Rotor Blade?
    There is so much more to rotor blades than the material they are made out of I feel there would be little value in assigning characteristics to the material.

    I have no experience with a Subaru EJ25 so I can't help you. If you lose 1,000 rpm by changing the exhaust I suspect it is not the best exhaust for that engine....

  • I didnít say there was poor attendance Chris; only that there were more people at AirVenture.

    The PRA Convention was well attended compared to recent years.

    Steve McGowan was there and training in The Black.

    Ron Menzie was there to give a seminar about check...

    I suspect the exhaust is not working well in your application.

    Go back to your other exhaust and see if you find the lost rpm....

  • You don't have to look very hard to find lots of pictures of AirVenture Chris.

    There are fewer pictures of The PRA Convention at Mentone because there were fewer people there.

    It appears some of the prolific picture takers weren't there this year....
