Still waiting for that hand calculation for the aircraft neutral point.

What I mean by "posing" is how are you going to bend the CAD figure to sit in your cockpit? Having a figure is fine but unless you intend to have your pilot stand (like an early Sikorsky design), you need software that will pose your figure in your CAD drawing. See attached.

If your software will read obj format, try here: https://www.daz3d.com/?utm_campaign=DAZ 3D Brand&utm_adgroup=daz3d - exact&utm_keyword=daz 3d&utm_source=bing&utm_medium=cpc&utm_matchtype=e p.s. How do you intend to pose the figure?

There is an important omission in the calculations for the "Constraint Analysis". Put there on purpose to see what would happen. All of the calculations are simple "hand, closed-form" calculations any high school algebra student should easily follow. Since no one commented on any of them, I...

Bored with amateurs

I kid you not. They stole my idea. This is identical to an aircraft I designed in 1986 except mine was smaller. I was going to power it with my ZL-1. What you do is take your favorite laminar flow airfoil and sweep it around a central axis. Presto, a laminar fuselage with minimal drag and...

I have been retired for several years. In the last year I have been designing a new airplane.

Vigilant1, Thanks for the interest. I intend to start my own thread about my design. I don't want to go "off-topic" in this thread. I also appreciate the heads-up about "The Beetlemaster" thread. I will read it all.

OpenVSP is a fantastic program. It challenges you to be a good engineer... to further your understanding of the "how and why" of your aircraft design. It allows easy and quick reconfiguration of airfoils, cabin sizing, engine/prop placement, empennage sizing and a whole lot more. This is my...
