Thanks, DAG

It'll be worth it, even if just for this project. There are barriers around a few things for some reason, but for the most part, it seems that you can get really up close and personal with the planes. I don't think they have problems with you touching them, poking your head in the intakes, etc. At least, nobody came up to me when I was doing it to shoo me away!

and flew on the wing

don't they all?

the part I enjoy most about your builds is seeing the CAD photos and renderings. You are a master with 3DS Max!

I'm curious here - you mentioned in the -36 thread that you frequenty do your modeling on the road in the hotels. What kind of hardware are you using to model with?

Even a brick will fly given enough power. Anything will get off the ground with thrust-to-weight ratios greater than 1:1, which are not uncommon at all in contemporary model aircraft. Many fly models by relying on brute power which is not satisfying to those seeking scale-like flight performance.

I think the expression "on the wing" is saying that the plane relies on having enough thrust to drive the wing well enough to generate adequate lift and fly with scale-like performance and maneuvering. If I understand Dag's comments, "enough" is somewhere in the 0.25:1 to 0.5:1 range.

I just 3Ds max on my laptop. It is a bit slower than my Hal 9000, but works good.

And flying on the wing is a vintage concept now days, many have huge over power power systems that drag the plane through the air so fast it looks silly.'

Thanks!

Spot on right, couldn't have said it better.

Cheers!

It was more or less a joke. I understood what you meant...

I know you were joking, would be hard to hurt my feelings.

Rock On, and be safe.

Dag!

So... I'm guessin you may want to stop by my neck of the woods again and check out our A-7?

Yep.

Thanks, Damon

I am slowly getting all the data I need to design the beast to as close as 100% scale as I can. On the C-130 design I found that by designing a full scale model of the airframe and then scaling to what I would build is the best way for scale. I was lucky enough to get TO on the C-130, so drawing that 100% to scale using the Station Lines, Water Lines, and Bilge Lines I can get a airframe very close. But this takes a TON of time. My B-36 was a huge learning curve, as was my B-29. But now with the A-7 I am going to do this as close to scale as possible regardless the time invested. The B-36 is my biggest priority period!, but this design will get ramped up when I can't spend my free time on the 36.

Attached is a wing panel with SL/WL. I will pull all of this into CAD, then design the wing from this.

Thanks, DAG

I have been swamped with work. And I am getting nothing done on anything, but late at night when everyone is asleep I do get to play on the puter and design.

Here is a cool 3D of my gear design.

The wing design, which covers the folding, and leading edge device is looking cool. I will post those soon.

Thanks, Dag

Here is a hint at a crazy thing I might attempt, and the intake and exhaust is .12% bigger than both of the fans area.

I'm guessing 2 X 127mm from looking at the size of the hole in the bulkhead of the original video.
