Whichever direction the Department of Aerospace Engineering, University of Illinois at Urbana-Champaign is.    Spend 4 years there.  Whatever you do do not take seriously any information from the myriad of ''experts'' in any hobby forum.

You can stall an airplane at any attitude, at any airspeed, when you exceed L/D max which is the lift to drag ratio!

This thread is about aerodynamic schooling. I challenged it's merits in terms of both time expended and also in terms of practical, real world application.
A speed contest between two .061 [1cc] powered planes is the purest, most basic form of practical knowledge applied...NO...?
There is only the stop watch, the doppler recordings and the onboard telemetry to dispute....no judges, no politics, no white loafers and no "Team Futaba" shirts.
If 1cc is too small for you, then we could shift up to 6.5 cc [.40] size. That would UP the ante though.

Speed and power are NOT complete aerodynamics.  The F-104G had razor sharp wings and a big engine that allowed it to ''fly'' very fast.  But ''fly'' it did not.  It was fondly called the ''missle with man in it'' because if it lost power it dropped like a rock.  Flying is the art (yes, art) of getting a 750,000 pound airplane off the ground with only 250,000 pounds of thrust.  That is aerodynamics.

But I do agree that aerodynamic schooling can only get one part of the answer - practical experience gives the rest and that is where the ART comes in.  But don't mistake ART in one area (speed or power) as having complete practical knowledge of flying.

I wouldn't dare challenge an aerodynamicist to a payload competition. Of course as modelers, that's the exact sort of airplane that most of us choose not to either build or fly.
I'll make you the same offer, a simple speed contest with a limited power source. It's a nice, simple opportunity to demonstrate how a classically trained aerodynamicist should be able to blow the doors off some bumpkin who got his knowledge off the back of a Wheaties box.
Don't you think so..?
