gmair, great Q, my 66in edge lands ok without any flaperon but the other day in a little wind i was having a little bit of trouble getting her to come down and i added 4 clicks down(you dont need much) and it helped alot.
so i used it later without wind(4 clicks) and it is landing sweeter now than ever, if you are still building and not maidened yet i would suggest landing it without flaps first and go from there so you know what you got, but with these types of planes you dont need much input to change things drasticly
good luck
