Aha - here is my latest one and so far the best slow stability planform -
(show it to Tony)
actually -it is a scale Cassut - powered with a 4100 HiMax - 850 Tantic 11.1 v- very strong.
The layout is totally rock free in high alfalfa descents-
My other tapered planform stuf would rock some and tripped out unexpectedly from tailslides - I have two of these and they both fly the same in this respect - so the layout must be a factor.
This is 3.3 aspect ratio - much like a bipe in that it is extremely stable in very tight turns and totally stalled stuff.
I am actually going to use this layout for my free style and sequence IMAC plane.
May look funny but it sure works.
