which is best depends on the task-
I am still amazed at how docile my 300 sq in 12 oz electric is to fly - even at slow speeds .
It just looks like it should not work .
wing is flat as a pancake - no dihedral- (low aspect ratio) and steady as a rock.
it also glides - but that is not it's forte.
probably about 4-1.
but under power - it simply does all the tricks.
The one great part 9is that I can try any thing and if I think I am going to stuf it - I just shut it off and let it crash -
a little epoxy and away we go
Way back in the beginning of time - controline speed stuff had wings/fuselages etc., carved from granite (I swear )
these things were also very smooth and stready and would glide beautifully-with a a little of the whip laid on em.
