As you'll have
gathered, I'm on
holidays in north
Queensland. On
this page are
images I've
gathered along the
way.
While in Longreach, a visit to the
Qantas Founders' Museum is a must.
The photos show the main hall of the
museum and a replica of one of the
company's first aircraft, an Avro
504K, and the original Qantas
hangar.
Yes, I'm still flying model aircraft, namely the
Nadar, which carries a camera to 500 feet or
more. Here's one photo, a dry creek bed south
of Mt Isa, complete with nervous pilot and his
car (inset). For those not familiar with the
Nadar and its abilities, see Wingtips, September
2011.

Answers to the page 1 questions. 1. De Havilland.
2. Qantas, who leased it to the Royal Flying Doctor
Service. 3. An air ambulance, used from 1934 to
1943. 4. A DH-83 Fox Moth. It looks a lot like a Tiger
Moth because they had many parts in common.

The Flair Puppeteer, a 1/6 sport scale Sopwith Pup built and flown by Bob Raadts
Although this looks exactly like a
WWI Sopwith Pup, it's not quite to
scale, having been tweaked to
improve the flying characteristics.
(For instance the cowl has been
extended so the engine is further
forward, solving the problem of the
centre of gravity being too far back
for stable flight.) Hence the
manufacturers of the kit call it the
Puppeteer.
Bob built it from the Flair kit and
covered it in Solartex. For the decking forward of
the cockpit Bob used thin aluminium sheet that was
formerly litho printing plates. It's tricky to apply as
it's easily dented. To minimise weight aft, and for
scale appearance, there are pull-pull cables from
the servos to the rudder and elevator.
The model is powered by an ASP .61 four-stroke.
Ensuring that you have the correct incidence on
both top and bottom wings is difficult, Bob says.
Members who were on hand to see the Puppeteer's
maiden flight could see that it's a 'floater',
preferring not to land, but to glide a few metres
above the length of the runway. Consequently Bob
had several attempts at landing until he managed
to reduce the engine revs to idle.

Reminder
Even if you’re using 2.4GHz
equipment, it’s a good practice
to put your key in the frequency
board when flying.

Above right: Andy Brough's Hi Climber, seen in last
month’s Wingtips, is now repaired, and is flying
particularly well. A worthwhile electric conversion
from rubber power!
