Doxillia,

There is a lot of interesting stuff and important physical effects, but most people do not believe they exist and oyher does not find it interesting.

When you try to fly in "all" weather conditions or experimenting with “cruise control” as do, you find out it all yourself. Design a airplane, very interesting!

As example

The only moment I did use tip fortex solutions “winglets” was when I did design (+/-1980) canard models for contest flying with limited span (2m) and not the use of ailerons.

The extrem “backwards banked”, drag rudders (there is the first Contest Taurus of Ed again!!!!) did make flying like using frise ailerons possible (Orion!!!), look to the dihedral of this glider! But just as with frise ailerons no inverted flying!

So first goal (classic pattern?), then important facts (program to fly?) , then type, for the points to win (tricycle, taildragger), and then design (brakes, dimensions, airfoil, power, weight).

Think about this, Paul did tell us the Orion (taildragger with angled tail cone) he did fly, floated, just as Ed Kazmirski wrote, I have the same experience but also the Taurus does use the straight tailcone as a brake (of course the contra situation!) when try to get landing points.

I fly both Taurus and Orion. Orion does also use “Ground effect” that can be good or bad. (high weight Orion with retracts, so "GOOD")

So not trying to become a professor in the fluid dynamics, wasting of time.
Tell the important facts we all can use and try to explain. Downwash, wind gradient, groundeffect, propeller effects, etc.

But the first most important les to learn is:
The more you know, the more you know you don’t know!
