    Can someone who has flown a Sparrowhawk give their impression of the
    AC. What does it do well? Can you really compare this sailplane to a 15
    meter or any current sailplane? Can it be a serious cross country flier?

    It's more of a marketing blurb than an actual account of what happened
    at an event.

    some people would consider it a bit misleading to say that on May 14 a
    sparrowhawk flew the longest distance of the crystal squadron. While
    failing to also say that the sparrowhawk was the only glider of the
    crystal squadron to fly xc from crystal that day!

    Hang gliders have flown diamond distance, so they should be considered
    serious cross
    country fliers also.

    Something of an engineering marvel, in my opinion.
    Pleaseee, if SH is an "engineering marvel" then constructor of Pewee
    should get a Nobel prize...

    In January both Dean Carswell and I performed a number of test
    flights with the Sparrow Hawk at Caddo Mills, and we both were quite
    pleased with it. The results will appear in Soaring soon.
    It was very easy to fly, and to prove that, I somehow made 8 perfect
    (in my opinion anyway) landings in a row. My wing loading was 5.15 psf,
    but that included the 25 lb BRS parachute system.

    The PW-5 has performance and materials and
    weight within 30% of quite a few other gliders, including

    the Russia and Grob 102 club.

    If you are aware of a glider which has more than
    a dozen produced by the factory which is within
    30% of the performance and empty weight of the
    Sparrowhawk, I would love to read about it. Please
    post this info or e-mail it to me.

    The Carbon Dragon seems the closest (and I also
    consider it an engineering marvel) but the
    difference is there is no factory producing a
    finished glider in any noticeable quantity.
    To my knowledge it is a
    onesy or twosy amateur built glider.

    It also gets its
    performance by use of flaps, which I (being
    a tilter) consider cheating...
    :P

    I am curious if anyone has performed spin testing with
    the Sparrowhawk yet and I don't mean from owners who
    say it recovers fine when they only had the first indication
    of a spin.

    Sorry, I meant to say first indication of a stall before
    it broke into a spin....

    What kind of performance? I am still waiting on an
    independent flight test of this ship.

    The idea of an 11 meter ship with 36:1 glide ratio
    seems unrealistic. I also wondered how a 150 pound
    sailplane would have any penetration into the wind.
    It's not 150 pounds when it's flying, but with the pilot, typically a
    BRS, instruments, battery, etc, it's between 350 and 400 pounds. That,
    and the small wing area give a 5 to 6 pound/sg ft wing loading. It's not
    a "floater".

    All,

    Thanks for the information and sharing your thoughts. I would really
    like to thank Eric Greenwell for taking the time to write the articles
    in Soaring Magazine. I look forward to reading the .... Johnson report
    in the near future. Now time to schedule a trip to the northwest and
    take a look for myself.

    When I saw the record set by the Silent 2 I went to the web site so
    that I could compare specs. They seem similar which is encouraging. Was
    Dave's flight a ridge run ? I live in Texas so most of my flying will
    be theraml lift . Anyway I may be out west soon I am going to go take a
    look, seems like a fun little glider.
