Hi everyone , i am a new in this forum site , i have one or two questions for my new rc plane . İ built that conventional rc plane but i am a new to built a canard . I don't know wing surface area calculation for canard type aircraft. Wing surface area calculation of conventional aircrafs is basic too , only front wing area but canard's have 2 wing that ensure lift for aircraft . Can i add front and back wing area for calculations ? Thanks a lot
