Never , was I looking to make someone angry .
My imprecise ramblings are intended to simply present another viewpoint
Albeit to some , a cockeyed one --
To pe perfectly blunt tho -- If I had persued model aerobatic design based on critical airfoils and closely limited CG positions, etc., I would have spent way too much time with very little improvement .
I instead , looked at power and wingloading as the only meaningful ingredients (as do all the new aerobats).
I did not realize how little TESTED, PROVEN info there was for these types of models.
As many advocates of 3D flying have found -- you can get a powered aircraft to do many things never considered possible
All with airframes and setups once dismissed as unworkable.
