Hi Art.
Cover the wing flat. When you add the tip dihedral, let the joints dry well. Use a brush dipped in whatever adhesive you used to adhere the film (I use very thin rubber cement) and paint the adhesive next to the rib on the baggy side. The OS film will draw right up and become almost taut. Let dry for a few hours.
Tips being flat rather than ribs is to reduce the tip drag as I understand it.
Regards.

I can handle a tailored dihedral joint using Esaki or condenser paper and they come out pretty neat, but this won't be possible (for me, anyway) with film. I have a choice between baggy panels on either, or both, sides of the joint, or making the dihedral break rib flat instead of curved and getting a nice taut job of it. I've noticed that the tip ribs on most indoor planes are flat (Hangar Rats being an exception). Is this for aerodynamic reasons, or structural?? And If the dihedral joint is made the same way would it wreck anything? Is a small area of the wing with a taut flat airfoil worse or better than the same area curved but baggy (which would render the curve uncontrolled)?
