Jack1933, the manual does state clearly the incidences for the wings and as far as this manual I scanned in goes, it cannot be refuted. These manuals are the original declassified and then non-classified versions.
Perhaps the guy you know has either made personal changes to the wing incidences on the planes he is associated with and found their stall rates to his and his customers liking or there is a non-military manually with specs more directed to the “crop duster” which may have a more critical stall requirement then that of the Stearman in use as a military trainer.

Ok You win Im just telling you that your info is wrong, because my friend just this day read the settings to me, and if you want to set your plane up in this manner, then try it and see what happens. Remember the way my plane is set up -2 degrees on the top wing with reference to the bottom wing, requires no down trim on the elevator at any speed, is a 16 year old tried and proven fact. Have sold many sets of these plans. I know what works and what does not work on many biplanes. Thanks for the offer of the manual, but dont really need it.

Jack1933,
I'm glad you have had such good success with the incidence settings you selected for your Stearman. Show us some pictures of this tried and true aircraft.
Jack1933? Is that the year you were born? That would make you 74 right? If that's true "keep em flying" Jack. I hope I do as well.

Jack1933, just for grins and giggles can you have your friend send you the page where he found this info? If it is from a military Stearman manual it would be an interesting find to see that there were differences of that type.
Just for clearing the air here, those of us who really use this forum are not the combative type, we seek only information and information by its very nature does not come unless questioned. So we ask questions only in a good natured way for clarity and understanding.
It is obvious to those who have modeled for many years that a 1 to 1 scaled down version of an airplane spec by spec generally will not fly well at all. There are gives and takes in appearance and in surface configurations that have to be made in order to have an airworthy scale aircraft, including the incident of attach by the wings and wing length.
The Flair kit is a good kit, the mfg took it to a certain level in flight characteristics and scale appearance, we are trying to take it to the next level.
Lastly, anything that makes it fly better is welcome...

Yes Ill be 74 in may Thanks for the kind words, cybertom, hope you can be active also as you age. Im going to fly 5 -I.M.A.C contests this year with a 40% laser, gonna mix it up with the kids--lol. the friend is sending me the correct Boeing rigging, page, when I get it will post on here. BTY, have seen the drawing cybertom posted and it is military and not the correct rigging for the Stearman, and my friend did not make any changes to the offical Boeing manual. The full size Stearman is rigged with incedence guages from Boeing, so it will be in specs. Dont know how to add a pix to this message, went to ---click here to update images and files-- and selected a pix to add but it did not show up here. So if cybertom gould give me a lesson, would appreciate it..Later Jack

Oh the pix did show up--oh well guess I dont need a lesson. the damage happened when a wood prop blew up. This pix was taken at the Guthrie Ok fly in in 2005. All the damage was repaired quickly, and thats when i changed the top wing from1.5 degrees to + 2 degrees--bottom wing at +3 degrees.

Jack1933,
That's one hell of a good looking NAVY Stearman no matter what the incidence! It has a very scale appearance. What scale is it and what did you use for a reference?
