That is the finest kolb tip I've seen so far.
Must have been tricky to shrink.
Busy day of moving vehicles today. When you live in the north
country and don't have a lot of storage space it means shuttling
contraptions to and fro that haint run in 6 months.
-jumpering the dead ignition on the old Massey.
Took a gallon of Molson's but I did it. The Kolb is back up at
the runway, at the mercy of the rodents, bees, wasps, coons
walking all over it.
Now to get my good brother to help spread the wings.

Just catching up on the conversation but need to put in my observations concerning wing tips......All the fancy expensive tips will not do any more than flat pieces of 1/4 plywood at the end of the airfoil. Cropdusters have been doing it since the end of WW2 on just about every early spray plane that was used ...consensus was that a fence on the end was good .. A lip of 6'" to 12'' above and below the airfoil all the way around depending on your own preference...ugly ....but it works. Lots of Stearmans were set up this way and I flew one for a while . Added effect was the wingtip vortice is reduced that helps in a better spray pattern and reduced drift...Early experimental guys had the same result in that it increases control and lowers stall at low speeds and helps at cruise...
I remember hearing the story of the Cherokee driver buying the expensive x-brand wingtip and flying his machine with no apparent improvement....decided to replace one tip with the original and left the x-brand on one side and flew it with no difference in handling ....then removed all wing tips and no change again . Put the fancy ones back on cause it looked " purrdy"....Is this just an "urban legend" or is there some fact to it ? Anybody know ?
On the subject of Scott Crossfield ...I'm dissappointed in Chuck Yeagers comments (if true). I would think he would be wise enough to know not to criticize a dead pilot when the facts aren't known yet...Even when the facts from the investigation are in , key info may be overlooked . I have seen accident investigations botched so the best policy is to grieve their passing and shut-up...
