I was trying to avoid work and realised that I had done this once already.
I figured I had really low fpea design in my drawer and also counted the frontal area for it and seem that the relation is around 1/20 fpea/frontal area...and flaps out and gear extented 1/30 ( if compared the to the best fpea ) !!!
That is why I had to scrap the project since I intented to use 22 hp engine..the drag increased by 50% as the take off/landing form was initiated.
This was very streamlined design.

The FPEA is considered a constant here ( the lowest possible ).
