Default Airfoils



I'm sure this has been brought up before but what are the current hot airfoils and what percentages are they? Reason for asking is that I am starting conctruction of some warbird racers for next year and the model selected is quite close in size and weight to a Q40.

Sorry brother, just trying to be helpful

Here's something you my want to try once you have an air foil in mind,,, Give Bob Mellen a jingle at www.flyingfoam.com , he's got a little foam CNC cutting biz and can cut any airfoil for a small fee plus I'm sure he's got all the scoop on whats Fast and a variety of different foams from lite to heavy(strong).


cheers!
