I know I'm building one. The hoerner tip is not as good as a winglet at stopping the lateral flow.

CH 701 already has hoerner wingtips like the 601 which act similar to winglets. ZAC website has the design info.

Has anyone attempted winglets on the horizontal stabilizer?

I was wondering if it may be a good idea for a seaplane.

It would help with weathervaning and possibly give some more authority with the elevator controls.

Hello List:
Slotted airfoils are interesting VG's seem to be fairly controversial. Now why don't we start a discussion to add winglets to the CH701 wing. As it does on commercial jets it will prevent the lateral flow of air around the wing tip and create more lift.

BTW Bernoulli provides about 10% of the lift of and airfoils - Newton does the rest by banging the bottom of the wing into air molecules. The airfoil shape allows passage of the wing through the air with a minimum of drag.
