Back to the routes

Mahalo,
It was idea, vision and try! The rest of the steps just follow!
The small DLG glider, 1m wing span, for flying on the backyard!
The steps done, Cad drawings of the new body, 3D printed prototype, reinforced
with some CFK roving /it works/! The wings out of Moth foil mold!
tails from 2mm balsa, boom CFK ravings on the conical pool!
The fist K1 glider fly well, so we decided with friends to make real one!
Not dedicated for some DLG competitions, more on the friends/fly/fun side!


Sandwich wings, styrodur core, vacuum bagging



Look of the K1 #1


 
New CAD body


And the video of one of the first trows!

Stay tuned, its fly ;-)

Not the last one, I was working in past monts on the "big" drone in size of
3,7m, the construction in full CFK, weight of the constr only 6kg, the full fly
weight 25kg! The whole project is under NDA, so I can not share more precise 
info online! The representative of DADA agency will understand ;-)

14 Years

What a coincidence,
when I agreed to test the new Hydrofoil board, I did not even have the idea that I will meet a 14 years old kite surf  board, which was produces by me in 2000, completely up to date for that time.
There is 14 years of development in the area of ​​kite products.
Newbie meets the oldie, nice feel and they looks great together ;-)

  
 

Some successful board test was made ​​later and here it is the photo documentation. Looks well an it is good to see the Hydrofoil driven by the young power! Yari do his job well and we are all waiting for the next stage of R & D! Test was made in cooperation with http://www.kitelife.si and http://keka.si/ driven by mr. Boris Stepanov! Thanks guys!

Wait and see this place for additional info on the new foils, the development is going to Switzerland
 and yes into the workshop are the CrossOver foils for http://www.ahcustoms.ch  ;-)

Infusion composite

Mahalo,
lets go step by step on technological procedure on the new race board
designed on my side. True weary complex construction of outside
fins on this board the end decision was to use the infusion technology
to get the ruff plate of GFK. The simply mold of Styrofoam was made
and in next steps the 12lyers of glass-fiber was lay down on the
positive mold surface. Vacuum bag all around with inlay tube for
epoxy, on the other side the air out. Less then 1h the resin was come
true all the laminates. Slow flow of the resin true the 7mm of glass fibre.

Front view of the fins block material
And once again the flow of the resin true the GFK, like a miracle!
The middle fin material was prepared on the same technology,
only the "mold" was plain table!
It was quite hard work afterward to get the fins in right shape,
but they are looks great when are mounted on the board.
