Could not agree more, we have lots to learn from our free flight chums!

So many well proven and many hours flown types.

All with inbuilt stability to boot!!

Hi Andrew, take a look on the web site, there you can down load a detail and spec sheet, the aircraft fully set up with long range video, Auto pilot, ground station, spares and training course in ops and maintenance is around the Aus$ 300k, not cheap but very capable and easy to operate.

BRG,
Chris.

FYI. The Ground Control System pic is that for a SKYLARK UAV not RAVEN. I'm looking at one across my desk :)

Cheers,

Marc

Have a look at my photo's.
My plane is a lot like this one.
My prototype was 1/4 the size, about 320mm long, 150 mm high, 40mm wide, large horizontal and vertical stabilisers, no controls, just a "chuck" glider and it was very stable. I got good pendulum effect with only a little dihedral.
I tried it as an autogyro as well. Even with a single 4 bladed rotor, 300mm in diameter, it had no roll tendency.
It even glided! Which I didn't think a gyrocopter could do!
I went on to try a tandem configuration with 2, 4 bladed, 300mm rotors on a 40mm wide wing. Which also had a good glide angle.
This is why my fuselage sides on my current model are made from cardboard, it is 220mm or 8.5" high,
It's a bummer balsa only comes in 100mm or 4" wide sheets!
Pizza box type cardboard is the best to use, you get great penetration with dope or polyester resin.
Cheap, easy to get and work with.
Don't try "double wiggle" cardboard though, it doesn't take up dope very well.

I See Alot of people with Discussing Models " LIKE" The Raven. I Think the thread was started with the Idea of an Actual 1/1 SCALE Model. I'm FINALLY To a point where I have time to work on this again. So Hopefully I'll be able to Post some pics of my progress.

Don,

That was the idea, a 1/1 SCALE Model.

I am still interested.
