Fokker E.III wing warping.

[Dan_San_Abbott]

Ladies and Gentlemen:
The subject of the amount of force to warp the wings on a Fokker eindecker came up a while back, I now have the answer. Last Saturday at Chuck's Bar-B-Que I found Javier Arango and I asked this question, "Javier, How much force does it require to warp the wings on the Fok. E.III?" He replied, "Why don't you check it out for yourself, Dan" and went off to get a ladder so I could get in his Fokker E.III 105/16. It is a beautiful piece of work, Chuck Wentworth and his crew of top notch mechanics did a suberb job building it, (I furnished Javier the method of covering and the marking data). After Javier returned with the ladder, I climbed into the cockpit, (not very easy for an old fart like me!) I was amazed at how easy it was to deflect the wing, 5 to 10 pounds, and about 15 to 20 pounds for full deflection, stick hard over against my leg and my leg against the fuselage side. Javier said you can add about 5 pounds more for flight loads. So it turns out that half-rolling out of a half loop would not be that big of a deal. (Immelmann Turn.) Javier is talking about a Fok. D.IV and a D.VI to complete his Fokker stableof oneFokker Spin, one Fok. E.III,one Fok. DR.I, two Fok. D.VIIs, and one Fok. E.V (D.VIII).
Oh, what a lovely day Saturday was,

P.S. Lee Branch and I met a very young lady named Michelle who was a well of questions about WW1 aircraft. Lee and I endeavored to answer her questions. One of the question she asked, was, "How does a rotary engine work?" Lee answered her question with such clarity, that I learned something. Did you know that a rotary IS NOT a reciprocating engine! Have Lee explain it, it really makes sense.
What a day!!!!!!!!!!!!!
