Well it seems I am once again gainfully employed this time in my industry. So now I will have more money to pour into my hobby but less time to do it.

Finally back to work on the PAK DA today.
I've made a new one based on the info from glide testing the previous three.
The elevons are reduced leaving the broad tail for stability. There may yet be a center piece to keep it ridged.
The wing shape and canard placement is exactly like the Su-47 Berkut.
I have added the elevons to the wing rather than cut them from it to make a more stealth looking trailing edge.

I had to take down my last video. It seems I violated Sony playstation's copyright by calling this PAK DA a "Krazy Ivan". It happens to be the name of their new FPS game.
Who knew?
So any body out there got any ideas for a name for this bird?

Niether can I.
I maidened it today. Didn't work out well. My bad. As I was doing the set-up I changed from the tried and true (works just fine on my previous PAK DA/FA) elevon set-up to an aileron-elevator setup which I had tried before and learned (apparently not well enough though) does not work. A funny thing about the Tailless Forward-Swept-flying-Wing, it needs the rear wing surface to be flat in order to be stable in pitch. Even minor trim can cause the plane to pitch up end for end. I put that finding aside and learned all over again that it is so true. Also in my haste to build it I warped it slightly which gave it an annoying desire to roll left.
Already begun building a new one. Slowly this time. Gonna have to buy a new Hot-Glue gun though.

Foggy and Cold here today with chance of rain and possibly snow later.
When I get my work done I'm cutting out another PAK DA Ivan and trying out my new hot-glue gun.

Found time today to build another Ivan PAK DA.
Took my time and added CR as I went to keep the main wing true.
Glide tests are positive.
I changed the wing-tips by striking the line from the tailing edge tip at 60 degrees back to the nose.
Methinks it makes for a more interesting outline.
