2nd Airship Indoor Pylon Race

Dear all,

please find the table of ranking for the Cologne Regatta in the files area at

http://groups.yahoo.com/group/rc_airship_regatta/files/Koeln/

Just in brief: each team flew three laps, of which the fastes lap
was assessed. As proposed, a racing formula was applied to give a
chance to smaller ships. Result is:

4. Kugelblitz, Gunnar Ztaut, Bremen, 52.1s
3. Glöckchen, Johannes Eissing, Hamburg, 37.6s
2. Tatzelwurm, Dominik Baumüller, München, 34.0s
1. Homer, Philip Neuhaus, Bremen, 26.3s

Photos and more comments will follow soon.

Stay tuned,

Hannes

PS.: Yes, this was good good fun ;o)

Hello all,

Hannes asked me to write a few lines on the race in Cologne because
he is very busy at the moment. It seems to be difficult to obtain the
eagerly awaiteded photos of the event at the moment, but I'm still
hoping to collect some and hope for your patience.

I'd like to thank the DLR and Herrn Scharenberg in Cologne for
providing a large space to fly the race in and a bottle of helium
which we got thanks to the quick wittedness of Frau Kuhn. The support
is much appreciated.

Another generous offer for heliumsponsoring by Frederic Gester was
very welcomed but not needed, but the next race is being planned:-)

A big thanks goes to the DGLR including this fun event in its LTA
Workshop for the second time now. The workshops participants were
great spectators.

Hannes, Gunnar and me arrived Thursday night and had the chance to
attend to fridays lectures after which we started preparing the ships,
fighting transmitter programs, carbon fibre rods and do some test flying.
Saturday we left the lectures early to do some final soldering, balancing
and still fighting transmitter programming.
Amazingly the ships were ready for the race at 15:30. Dominik arrived
two hours before the race started and had Tatzelwurm ready very
quickly.

After measuring the participants ships box-volume for which the lap
times were later corrected, Michael Bölling again competently
managed the race, took the lap times and announced the winner.

Dominik started first pushing forward from the start. Half a lap to
the finish Tatzelwurms batteries became weaker and weaker. The
spectators audibly feared him not making the line, his competitors
silently hoped he wouldn't, but finally he did and it earned him
second place using the formula.

Gunnar then flew Kugelblitz1 around the course. With propellers
constantly changing pitch, sounding like a big one corrrecting his
flight path. Carefully circling the pylons he finnished without
entagling the long engine outriggers. Kugelblitzs controllability
much improved, the straight line is still not its domain, but I bet
he was quickes round the pylons.

Hannes now shoved Glöckchens throttle to half power, never
touching it again. Commanding wide turns with the x-fins he flew the
most constant lap times recorded in indoor airship race history
finishing second place.

Gunnars next entry, Kugelblitz2 presented a roaring start with the
impressive power of 4 engines. Flying an amazing straight line to the
first pylon, astonished spectators witnessed a 180deg turn on a
and roaring engines again for the lap back. The sheer power and
dimemanoeuvrability of this spherical ship elated the spectators, but
sadly not the clock.

Homer slipped through the air, effortlessly pushed by its single
propeller. Banking 'round the pylons agressively, driven by the
cheering crowd. Then, in the last lap, a tense moment arose when
Homer didn't want to exit a turn. Aiming for poor Rainer Scharenberg
the pilot managed to bring Homer back on track to win the race.

The prize awarded by the DGLR for the winner was a round trip with
the Zeppelin NT.

It seemed the participants enjoyed themselves and entertained the
audience.

lots of greetings

Philip Neuhaus
