absolutely -
and I was fed the old theories of how wings lift and that's how planes flew - Once I finally got over that - things made sense.
for example --On our models - the airfoils are probably the least important part of why they fly -
wing loading and powerloading can replace almost any other "important " stuff.
The choice of the best airfoil, which is not what I was commenting on, does depend on the speed at which the plane flies, and is often not the most important factor affecting a plane's performance. The effect of CG placement on stability, which is what I was commenting on, does not depend on the speed at which the plane flies. It is a disservice to anyone expecting to get good advice here to make the false statement that CG doesn't matter for slow flying planes.
I have had some exposure to the 'old theories', as opposed to the popular misinterpretations of them, and I have also read several of your explanations in various threads. I have not yet had any reason to abandon the 'old theories'. You just need to know when they apply and when they don't.
