Lee Smalley Posted November 26, 2009 Share Posted November 26, 2009 well most of teh info should be got from flair themselves but as a rule of thumb no further back than 30% of MAC (mean aerodynamic chord) of the wing example root chord 300mm tip chord 250mm if the wing is not parrallel 300+250=550 divide 550 by 2because you want the mean of the root and the tip 550/2 =275*0.30=82.5 so start with 80mm back from the root and go fly from there its the formula i have allways used (if i have had to) and its never left me in deep poo poo Quote Link to comment Share on other sites More sharing options...
