I am modeling a RC plane as part of my hobby and I have run into a modeling problem in the wingtips. I have a airfoil and I have a profile that I want the wingtip taper into, but am having a hard time understanding how this can be done smoothly. In theory I’d like the taper to be consistent, or at least steep at the front and less at the back. But how do I determine the distance in from which to trim and taper the airfoil? The airfoil bulges to a maximum at about the front third, and that is really messing me up.
I am asking from a modeling standpoint, not from a aerodynamic standpoint. The plane would fly even with a squared-off wingtip.
