Well if you ever want to fly in competion, you might want something more modern.
''Real'' F3a airplanes may look like a fish but, ''form follows function.''as they say.

I know this forum is about ideas and theory of flight, I enjoy that as well, But I`m not thumbing through a engineer manual ,to answer commons sense questions ,Experiance,and practical application trumps arm-chair theory.
It`s easy to overthink things and look smart then make your conclusions fit the outcome you desire, but, in the real world of competion and pursuit of perfection we have to be able to back up our theory with results! not more theory. These results influince the new theory ,not the inaction of thought and intellectual belligerence.

Model airplanes are not bound to full scale rules Many things change when the wing loading is decreased.
This discussion started on the rational of trimming I gave the practical answers and it was aurgued with more theory.

Dick design a 2 meter Dalotel with a flat plate wing ,Then try to get someone to compete with it

it`s easy to deflect what can`t be aurgued with proposterous thought! and change the spirt and intent of the debate!
it`s another thing to stay on the same page and back your claims up!

Nat Penton and I had this debate for many years, till he tried my ideas and guess what, it changed ''his'' thought process!
After he could no longer deflect my methods with theory ,he tried my approach, and it changed his thoughts.
and his setup process.

anyway, here is what a modern design looks like

Funny thing about fish is that they don't have a funny looking screw bolted to their noses, especially one that goes 'round and 'round.LOL
Talking form following function, I was watching the Science Channel the other day and the program of interest was the Deep, 10,000ft below sea surface. There was a fish there that had the whole front of its head covered in a clear bubble, like a clear canopy of IMAC models. That was to protect its huge eyes. That far down many fish chemically luminesce faintly and if a fish is to feed, it has to "see" prey. Problem is it is as dark down that far as anything known, hence the huge eyes. That bubble canopy was fascinating.
