    Asking how the use of Horner tips effect wing length.

    I believe they add about 6-8" to each wing. If you need more accurate info, someone else may have exact measurements.
    I have them on my SS7, but if I were doing it again I would go with the standard tips. They definitely add more wing area, which I think is unnecessary. My kitfox seems to float longer and has a somewhat flatter landing approach than friends I fly with who have standard tips on their SS7's. They are supposed be more efficient in handling the wingtip vortices, but I don't notice any measurable difference. Others may have different opinions. They also make it more difficult to install wingtip nav and landing lights.

    George,

    The length may vary from build to build depending on how a person cuts & fits the tip; however, ours add about 14" to each wing.

    Dave's comment about the cuts is spot on. When I built my first Model IV, the plan was to fold the wings and keep it in my garage. With that plan, building to minimal folded length was critical. I cut them really short and modified the lower surface contour by grinding the glass a but thinner for easier bending to shape and then adding glass to return to the original thickness. A move rendered the need for short moot, but always liked the look vs. the droop tips otherwise available.

    Tanks for info! Think I’ll go with standard tips especially since I will have wing folded issues with space as Lowell talked about.

    I'm with Jim on this. I have Horner wingtips and I wish I'd stuck with the standard. I've added Nav lights and strobes, but I've had to cut and build support for landing/wig-wag lights. I've spent heaps of hours on this and not sure it was worth the trouble. So my suggestion is exactly what you're doing ... stick with standard.

    I want to clarify my previous remarks. Although a challenge to a degree, I never regretted the effort going with the then standard Hoerner wing tips. In fact it may have been one of the choices that gave my first Model IV one of its characterics – it was very fuel efficient. In our annual flight of six excursions to Idaho in the early 2000’s I always bought less fuel than the rest of the fleet. On the first trip at our fuel stop after the first 3 hour leg, I loaded under 8 gallons of fuel. Next was about 10 gal. and the highest, a Rans S-6 at a bit over 13 gallons. It should be noted that the group included a Model IV with a 582 and group speeds were typically under 90 mph.

    The following link will tell the story of the development of the Hoerner wing tip and possibly explain its introduction in the early 90s to replace the original droop tips as the standard factory wing tip.

    I do know the drooped tips can give you a good rap on the head that probably wont happen with the horner style. The flaperons can get you either way. It always happens when I'm wearing a baseball cap, and don't duck far enough. JImChuk
