Peter,
Not only is the wing low, but the aircraft climbs with fuselage level, due to
the seven degrees angle of incidence of the wing. This not only gives
exceptional visibility on climb, but in addition the climb is completely
without any P factor. i.e. climb is made without any rudder input. Descent and
cruise will of course require rudder input in order to keep the slip ball in
the middle. Descent of course with a little extra drag will be an advantage,
and the aircraft is certainly not designed for cruising anyway. It is a
specifically designed tow plane. No other uses were envisaged during design.
And Gary, your question. The flight test phase for experimental aircraft with
non certificated engines such as Beaufort’s Hornet and my Pik is usually forty
hours. The first twenty will be simply boring holes in the sky. We are hopeful
that we will be given the OK to do the last twenty towing. That is where Jack
is at right now. First twenty done, and hoping to commence towing shortly.

Thanks Bob.
One of the things I like about the Pik 27 is the low wing. It just gives much
better visibility, which is so important to safety.
I am looking forward to your article.

Peter,
Unfortunately, John guilds the lily quite a lot. I am in close communication
with Jack and his team, and agree that Super Cub performance when towing is
more realistic. . However, if Aki Suokas performance figures for the Pik 27
prototype are accurate, with the 115 HP Rotax 194, then my Australian
prototype, expected to be in flight test configuration later this year, should
indeed outperform the Pawnee, with the same engine prop combination as the
Beaufort Hornet, but with less drag.
We shall see. Interesting possibilities.
Regards
Bob Ward

The Beaufort Hornet tug only has a 2.2 litre Subaru engine of 160-170
Horsepower. Therefore it will not outperform a Pawnee. We do expect that it
will have equivalent or better performance to a Supercub.

THE JULY 2014 ISSUE OF
GLIDING INTERNATIONAL
Our subscribers are writing to tell us they enjoy our new format. Thumbs
up all round. It has been a great move. The July issue goes in the mail next
week. Expect it in your mail box by June 27.
The issue covers over 60 new absorbing topics for yet another coffee table
issue. The photos alone make it a ‘must have’ issue.
• The authorative soaring journalist, Elk Fuglasang-Petersen (Germany)
writes for Gliding international about her personal experiences in gliding with
a Germany club and then comparing the experience with three years membership
in an American club. Her observations are entertaining and informative. The
differences are quite incredible.
• Aldo Cernezzi has written about his evaluation of Schempp-Hirth’s Arcus
E, the all electric fantastic two seater. Exceptionally well illustrated this
report points out all the goods things about the Arcus E and about its
limitations and costs.
• Our staff reporter Rod Dew writes about ‘Mr Aerodrome’ - a story from
the early 1900s detailing a catastrophic failure in trying to launch his glider
a top a house boat in the Potomac river in USA. This Smithsonian director could
have been as famous as the Wright Brothers as he had more answers to
directional control than they had at the time. This is a fascinating hitherto
hidden story of an exceptional pioneer. Did you know that Englishman Matthew
Boulton in 1868 was the first to patent the aileron? Rudders, ailerons, and
elevators had been invented long before the Wright’s efforts began. The
English patent was unknown to the Wright Brothers who had the greatest
difficulty getting a U.S. patent for their methodology.
• The 2014 Grand Prix is over and the finals flown at Sisteron, France was
an exciting event. Covered for Gliding International by Ritz du Luy, it was
all the more interesting because a Frenchman stole the crown.
• Schleicher’s new two seater, the ASG32 has flown and we captured the
first test flight, flown from Poppenhausen, Germany. A sailplane of beauty!
• The cost of towing aircraft gets more expensive by the hour. Two
unrelated Australian’s have built home-built tugs that are expected to have
performances greater than a Pawnee at less than half the price. A great review
and a helpful paper for any club reviewing their towing costs. All this is
followed by a review of the new Robin - Europe’s towing work horse. Great if
the club has $.25 million to spend
• We review Tom Knauff’s new book – a detailed collection of gliding
accidents over the past 10 years. This is fascinating and instructive!
• Two new, two seater electric motor gliders are flying. The Sun Seeker
and the Sun Flyer (unrelated). There is no shortage of new projects being
designed, worked on and projected to go into production.
• This is frightening. US Customs officials are insisting on searches of
motorgliders flown cross country. They have a misguided belief that they are
ferrying drugs. A detailed story on one such search.
• Research - A paper on how a university has been able to fly an aircraft
by ‘thought processes only.’ The brain was connected to an auto pilot!
• Plus 40 other stories that will educate and inform.
We hope you will join us.
