  • Congratulations on earning your Sport Pilot Certificate Richard!

    Because the Cavalon is composite semi-monocoque construction it takes some close inspection particularly in the mast area and where the main gear is attached to the fuselage looking for signs of delamination.

    Good morning George,

    My local Rotax Certified Mechanic works for an FBO on the field and I get same day response.

    Some seem to be working on Rotax as a hobby business and are not responsive.

    I prefer someone who works as an aircraft mechanic full time compared...

    Thank you Frank, I take that as a high compliment.

    I take the safety of my clients and passengers very seriously.

    I also have a low fear threshold....

    I am not a professional mechanic Chris.

    There are at least three A&P mechanics on the field that have a better eye than I do.

    Every time I strip her naked I have a least one of them stop by the hangar.

    The FAA has a wonderful book on how things are done the...

    If properly executed; that sort of leading link center hub steering works much better than a telescoping front end.

    I don't know if this one is properly executed; it looks well thought out.

    All motorcycle streamliners at Bonneville use a variation of this sort of suspensio...

    Good thought Juergen!

    The Sport Copter rotor assembly was purchased in 2009 and has about 1,400 hours on it. The teeter bearings and most of the hardware is new.

    I have the body off now; looking for cracks in the frame and inspect the flight critical parts before each flight....

    It is my observation that a common way for people to damage a gyroplane is to unintentionally let the airspeed get low and try to arrest the unintended descent by pulling back on the cyclic.

    Perhaps because of this "recognition and recovery from low airspeed and high rate of descent"...

    Good morning Chris,

    The Predator was started in 1997 and first flew in 1999.

    She is a unique design and I continue to be impressed with the details.

    Mark Givans occasionally drops into the Rotary Wing Forum even though he has pretty much gotten out of gyroplanes....

    I was building a two place tandem powered by an IO-320 (Mariah Gale) and ran out of money Chris.

    I had a lot of fun and don't regret a minute or a dollar of the process.

    The gyroplanes I have flown let me know when I have diminished control.

    I try to approach the edges of the flight envelope progressively.

    With almost all of the gyroplanes I have flown the envelope is so big there is no reason to get near the edges even if with very aggressive...

  • I am glad your luck is holding LuckyLuciano!

    I was taught to avoid the shaded portion of the height/velocity curve in a piston helicopter.

    I was taught to do a performance takeoff when that wasn’t practical.

    I do not have a helicopter rating so I am not inclined...

    Welcome to the Rotary Wing Forum Candace.

    Please get some training before you fly a gyroplane.

    They are very different than a fixed wing or a helicopter.

    I suspect you won't be satisfied with an ultralight gyroplane.

    The five gallons is very limiting...

  • Thank you for sharing your fine workmanship with the Rotary Wing Forum Stephen.

    I find it inspiring to see such thought and care put into the construction of a gyroplane.

    I look forward to following your flying adventures....

    It reads like progress to me Chris.

    In my opinion learning to fly a helicopter is harder and more expensive than learning to fly a gyroplane.

    I wish you all the best on your aviation adventure....

    It is my observation C. Beaty that you sometimes get caught up in the arrogance of "facts" and lose sight of how things actually work as a system or how they interface with people.

    I have not personally measured the effectiveness of a particular horizontal stabilizer in a particular...

    I suspect Jake is referring to a power push over at low speeds.

    In my opinion aerodynamic force is related to the square of the velocity of the air passing over the control surface.

    I feel a horizontal stabilizer dampens pitch divergence and in the case of a gyroplane with...

    My preference for a keel mounted horizontal stabilizer is based on flight experience with various designs and is not influenced by a misunderstanding about what a propeller slipstream is like.

    I am not a gyroplane "designer" or a trained gyroplane test pilot....

    We seem to be having a particularly bad fire season as could be expected from the rainfall this last winter.

    The nearest fire to me now (it started Monday) is the Pozo fire about 25 miles north.

    When a big fire moves through a neighborhood it can take out a lot of homes....
