2010 DARTS LSF and Fun Fly
Sunday, Sept 19, 2010
DARTS Field, Fairborn, Ohio
We had a beautiful day for soaring yesterday at Twin Towers if not a
lot of lift. We had two winches launching to the north west and a
slight breeze that picked up only toward the end of the day.
Ed Franz, John Lueke and Don Flemming put on a Altitude limited
Electric Soaring demonstration that answered a lot of my questions
about that event. When the motors shutoff there isn't much of a zoom
afterward and all three aircraft leveled out very close to the same
altitude or at lest so close that I could not determine which was
the highest. I also can say the altitude of 200 meters is equivalent
to a good winch launch. Not as high as a great launch nor as low as
an average launch but a good winch launch altitude. Seriously, this
type of event is the right direction for the DARTS club to pursue
electric events because the ability to thermal is paramount with the
motor used only to launch. Ed Franz and his collaborators have
achieved a balanced, economical and competitive soaring event.
John Lueke set up a hobby shop with an array of aircraft that he
wanted to sell. So, I super glued my wallet shut. Some others were
not so prudent and walked away with neat stuff.
Don Harris made several hour thermal duration flight attempts coming
up with a 35 minute flight. I figured if Don Harris with his Ava
and three scout planes ran out of lift it was best not to go on a
goal and return with my Mantas. My Mantas isn't ready anyway as I
asked Don to fly it and he gave me good advise for getting better
control. Mr. Harris also showed us how to hang your sailplane
upside down by the hook to get a reading on CG as it relates to the
launch. If the tail slightly hangs lower than the rest of the
aircraft it will launch good i.e. CG slightly aft of the hook. Don
also gave us a launch peddle seminar. I tried to take notes but it
was better to watch and listen to the steady cadence he tapped out.
Mark Groves beat me in a Vista last man down skirmish but I can't
remember how. I think he used one of those "Men in Black" memory
erasers on me. Mark also brought out a scale gull winged sailplane
that really is sharp.
Ken Davidson had his grand kids out with him and it was fun to hear
them talking about the airplanes and wanting to see grandpa fly.
For a short time Ken and I fantasized about 2.4 Ghz information
return technology that would allow for artificial horizon indicators
superimposed on a pair of heads up display sunglasses, then we just
decided it was best to go fly.
Don Flemming questioned Don Harris about ancient RC technology,
airplanes and events--I guess to try and determine how old they both
are. As I had little idea about what they were talking about other
than "galloping ghost" I figured they are both pretty old
it was a good day,
