Neurotex,
i had coreldraw running just now i so i measured the amount of wing area on the fling plans, and it came out to be around 15sq inches, not counting the upper wing, and thats only the 7" version. how slow do you want the plane to go would be the question, a 10" span version would give almost 30sq in of area, if you keep the AUW to around 15 grams, you'd have a wingloading of around 2.5oz sq/ft, so she could probably move about relatively slow, but still be able to rip. of course, if its heavier, she'll just move a little quicker
i'd start somewhere in the 10-12 inch range, if you want it faster, you could just trim some of the trailing edge off!
where are you mounting the motors?

That is a lot for a 10" wingspan so I better keep it no greater than that. Might
trim it down as I test fly it. Making it nose heavy with some up evevator will
speed it up some.
As for the motors I usually cut the slots first and then move the battery forward
or back to balance but on this design there's little room for that. I'll mount the
battery at the very nose, then the Rx, and then balance the plane with the motors
last. That will tell me where the prop slots should be. I'm guessing close to the CG.
