Finally today I could maiden fly the bird in light wind and sunshine. And it flew just like a real bird. After a few circles in the blue sky two other real birds showed up and were looking after the big intruder. No attack, just peaceful get together in the air. What a wonderful feeling.
Unfortunately no video

It was a holiday week and the forecast was bad. I decided to dig in the download plans and found a plan on the RCBirdz website. As I crashed or rather desintegrated my Ultimate (earlier posted in this blog) in midair due to high g load, I had an engine, a speed controller and some servos left. Depron is always in stock.
The Axi 1200 KVA is quite strong, so I blew up the plan of the Eagle from 37.75" wing span to 49" or 125 cm, which is just the maximum you can get out of a Depron sheet. To stiffen the wing I put a 6x1 mm carbon rod and laminated some glassfibers between the two layers of the KFM Profile. I also laminated the nose with some fibre as the carbon engine mount proved to be too prone to vibrations. The rest is basically according the plan. CG is very sensitive as all the heavy parts are very close to the CG but easily adjusted with the position of the Lipo.
It is still raining, and I can't wait to fly the bird and to mess up with all the crows in my neighbourhood ;-))...Continue Reading

Found time again to build some funny stuff. Its carneval time in Switzerland and I just finished this flying witch on time. Maidenflight was successfully completed yesterday, and today I finished the paintjob. It flies great by the way with a delta mix in the elevons and a rudder, all in the broom.
Thanks to Tom Schunk and his downloadable plan (FMT downloads).
However I modified the plan to a bigger size to carry a bigger motor and a bigger Lipo 3S/1200

I just maiden flew my SWISS DART today on beautiful and calm lake of Zürich.
Actually I intended to do some highspeed gliding on the ski first, but there was a little wave and hopp she got airborne. Well, therefore I continued and flew a few circuits. The CG seemed to be perfectly balanced but response to the elevator was a bit too strong. For the second flight I just added some expo (40%) on the elevator and she behaved very smoothly thereafter. Quick subsequent rolls however always ended in some murky manouver, most probably caused by the thrust vector. Alltogether she is fun to fly, and I hope we will have a lot of fun on the lake together.

And there she sits on the water (even after the maiden flight

Just finished another project today. Forgot to take pictures during the construction. Painting similar to the "Slow ride" from Aerofly SIM. I just liked it.
Plans are available on http://www.amjd.ch.
Website is in french. Basically just the drawings of the depron parts, no measures, no detailed construction hints. So I had to use a little bit of invention myself to finish it properly. Weight is 450 gr. Powered by AXI gold 1200 KV on a 1000 3S Lipo.

A big " Thank you" to Vleisie.
I adapted somehow his seadart plane and created my SWISS DART.
I used Balsa for the wing leading edge, integrated the pushrods for the elevons into the wing and used a different engine mount. I also filled the lower aft part of the fuselage with a boat shape.Driven by a 2000 KV AXI gold on a 3s 1800 Lipo.
Some pictures with the details before and after the paint job.
Isn't she a beauty?

Pictures are taken before the maiden flight:
