And this time it was not maiden flight. It was maiden sail. I guess that it is acceptable to do this as it was sail boat. Normally I do only maidens for Sail planes..

I have forgotten to add note of next build log progessing...

Located here :

Plane is Vinka L-70 Miltrainer. And for trivial pursuit hobbyists, Vinka means cold, northerly wind.

I have been enjoying long & warm Finnish summer holidays with limited network coverage. And now there is approx 3 pages new messages in subscribed threads. Wow. You guys do not sleep? It will take me ages to get things read.

New free design released... To be honest, original plane was built 1922 so it is not really new.

I ran out of aluminium skids for Harakka II-kits and visited local university protoshop for more skids... I just had to take photo of machine they used to cut alu-parts for me.

Think that this is most extreme machine to cut kit parts... Luckily balsa & plywood parts are cut with laser.

I would like to present an new product for your viewing pleasure. It is joint project with my 18yrs. daughter, Annie and me. Together we designed and built prototype for 1/3 Deck Chair suitable for scale glider pilots relaxing after long flights.

It has been flight-tested using AH Pilots 1/3 pilots, they seem to like it. Although that red-shirt-guy seems as grim as always. He is tough guy to please. Just see pics below..

Chair kit is quite complete, includes everything to get it up and running. You provide only screwdriver and glue. No cutting or drilling needed. It even has instructions. Fabric part and packaging are done by Annie.

As I want to teach Annie ways of life I am directing all the proceedings of this product to her holiday fund. So this is an product which is in some strange way socially conscious. The idea is to show that if you do something, there is an possibility of getting something.

Interested? Do not wait any longer, just direct Your browser to here and enjoy our superfast delivery times.

I guess that finetuning devprof- & devfus-stages of PIK-12 are done. It's time to move from CAE to CAD. Whewww! That was task. In particular, the inner wing panels which have negative arrow-form contained 15 spars (or hollows, not including lightening holes). That's plenty.

Done are:
1. Fuz design in devfus
2. Wing panels inner & outer in devprof, including aileron design
3. Rudd design in devprof
4. Elev design in devprof

I have already done most of fuz formers, tailpost, rudder & elevator design in CAD, but finalizing fuz-wing-attachement-points required finalizing wing design.

From this on it's only 'clickety-clack' of mouse & checking & checking & checking. No design anymore. Just implementing drawings (7 in total)

This is monster plane, 5m span, fuz height is 0,45m, rudd ws is 1,2m. Typical wing thickness is 55mm.

Finalizing 3d-cadding of my next bigger project. 5m PIK-12 'Gabriel'. This has waited too long time, now it's time to get hands dirty.

Managed to make rather good video. I guess that it is best inflight-video I have ever managed to edit. Video tech done by HSK who is much better than me in that side.

Music was surprisingly good also. Actually it was youtube-automatic-proposed music, but it suits video rather well. Crank volume to high.
