Yes Cees, sorry, I shouldn't write stuff from memory, as you quite rightly point out the tape was done after his Nats win. Which only makes it even more interesting, since even then, after the U.S Nats, he is still describing how to modify the existing plan to make a copy of his Taurus version. One wonders, given that Tauri was being prepared for kitting as well as Taurus, whether Ed had much time left over to produce the drawings or whether there was some other impediment to publishing 'his' Taurus drawings. Perhaps it is possible that even then MAN and Top Flite had come to an agreement not to publish any plans until the kit was ready and stocks manufactured. We know that the MAN plan is virtually the kit plan with added wing and fuselage sections, so maybe commercial decisions had been made as Top Flite wouldn't have wanted proper construction drawings in the market before the kit was ready, as that might compromise kit sales. Makes Dennis's recollection of brown paper plans even more likely if that was indeed the case. Anyway the RCM&E drawing shows 2.25" dihedral under each bottom spar at the tip, 4.5" total. Let's see how that matches up with the 1961 blueprint.
Evan.
