Will it fly?
UPDATE: LABOR DAY 2006
I let this project sit for almost two months, but have the old 911 running pretty good.

To answer my own question, it did fly.

However the saga continues as it did not do very well.

The problem is two fold, I need both additional lift and thrust out of my old craft to make the new experimental skirt work.

My goal never was efficiency or performance for that matter. My goal was increased obstacle clearance and stability. I can still reach my goal, but have to toss more into the pot to make it go.

There are descriptions in the upper right hand corner of the webpage links which describes what I'm facing and my thoughts on how to deal with it all.

I just took a saw to the lower front bow of the craft, except for the aluminum supports it's 100% open now. I just pinched the air flow too much before it could enter the plenum under the craft.

I will also Gorilla-Tape up some of the side bag feed holes so more lift air actually gets under the craft. The craft is still too stable and will not lean into a banking turn. I don't need all that side pressure in the bags, I need a real air gap to reduce friction.
