I received an Aerial from Thomas at Armsoar in HK and I am doing some development. This is a great plane and is a world class performer. Really really happy with how it flies.

Initial settings..
CG=75mm
E +/- 9mm
R +/- 13mm
Mode, Flap position, Ailerons (measured from flap pos.), A-R (Rud throw at full Ail).
Normal, 1mm , Up 10mm Down 5mm, +/-9mm
Th 1, 2mm, Up 10mm Down 5mm, +/-9mm
Th 2, 4mm, Up 10mm Down 4mm, +/-10mm
Th 3, 6mm, Up 10mm Down 3mm, +/-12mm

E-F mix was 3mm down with full up elevator in all modes except Th 3, it has 0mm.

I hope this is a good starting point and you can find your own sweet spot.

I finished 5th (from 91) in the warm up F3K Euro event and 38th (from 89) in the Worlds. I ran out of puff in the end after sitting 14th at the halfway mark. Really, really, pleased with how I flew. Thanks Jon and Hugh for being awesome team mates.

I am currently working on a new molded DLG project with Brad Wilman and Andy Smith called the Shark and you can follow the design philosophy and the building on the Shark threads..http://www.rcgroups.com/forums/showthread.php?t=1780060

My current love is flying DLG's and I currently fly a Salpeter, Concept and Stobel V3.

I started flying DLG with a Salome and it was simply the best fun in the world. Tim Lennon and I developed our technique together flying at lunch time in the local park.

In 2003 and 2004 I won the Australian DLG Championships with the Salome. At this time I was know for my very aggressive/high launches and I broke a few planes.

I designed the Blade (see below) with Tim Lennon and we learnt a lot about trimming and setting up a DLG, but it was not very successful becausewe could not launch it very high because it was too flexible.

I flew a NAN model Spin for a few years and we started a F3K League in Melbourne and this developed some excellent competition. See www.rcga.org.au

In 2011 I went to the F3K Worlds as the Team Manager and absolutely loved it. It was the best fun I have ever had not flying.

I have developed my launch technique over many years and I am still regarded as one of the highest launchers of a DLG in Australia (60m+). I enjoy helping out by teaching others how to launch high and I really enjoy posting on the 'Launch video - comments please' thread http://www.rcgroups.com/forums/showthread.php?t=1725624 .

Thought i'd let you all know who I am and what I do with some random ramblings:

I started flying gliders 28 years ago at aged 15 and have been addicted ever since. I have tried power flying at different times throughout my life but have always come back to gliding. I love the challenge of you against the elements.

I am a competition pilot, not because I am particularly competitive, but because I love how it drives you to be a better pilot.

I also enjoy designing and building my own planes and I am an engineer by profession. I have built a few vac bagged planes but really got into molding and I have racked up about 14 molded planes to date.

The Blade:
My first bagged plane was a DLG called the Blade in 2003 and it was ahead of it's time as the attached photo will show. I moulded this with a good friend of mine Tim Lennon.

The Mongoose:
I then built an F3B plane from CNC Aluminium molds using the HQW 2/8 and had mixed success with it mainly because it was too heavy at 2.5Kg, but I did manage to win the 2003 Australian Thermal Championships with it and did a 15.4 second speed run with it. Not bad for 2004.

The Machine (Hence my handle Machineman):
My second moulded plane was another F3B model and this time it was a joint project with Tim Lennon, Bruce Nye and Steve Boag. I designed a transitioning set of wing sections using xfoil and we came up with a radical low aspect ratio, perfectly elliptical planform. The wing section is 7% thick and has 1.4% camber.
I have done 31 laps in distance and have done multiple 15 second speed runs with it. It is remarkably easy to fly.
