Re: Yes... ANOTHER new guy just bought a Cougar/Tailwind hybrid, Bill in Los Angeles


 

Left to my own devices, I'd get it flying before making any improvements or modifications.? No telling how its rigging?and alignments have worked out. I'd hate to put a lot of effort into an airframe before I found out that it won't fly in rig.?

So I got some additional info on this plane from the seller, a great guy named Fred who was kind enough to have a conversation with me even before I go up there to get the airplane.

Apparently the original builder got a bunch of different incomplete project airplanes and made one flyable airplane out of it all. According to the build log, it's a Cougar fuselage (with Wittman engine mount/landing gear), and it supposedly has a set of Wittman W8 wings that were adapted together with that fuselage.
?
Obviously, the slight difference in spar spacing between the two designs had to be addressed somehow... I don't know if the builder made an adapter, a simple spacer, or moved the spar fittings on the fuselage frame.

But even though the plans-built W8 Tailwind has flaps, these wings do not. So this is also a mystery to me. This airplane originally had a 25 gallon fiberglass tank, which started leaking. So Fred bought a 17 gallon cylindrical shaped aluminum tank that was available commercially. Depending on the engine I decide to use on this, I might have to have a custom aluminum tank built (O-200 through O-290), or I might use the 17 gallon tank (Rotax 912, Yamaha Apex).
?
Thank you to the folks who uploaded and maintain the "files" section, I did see the photos and documentation on how Wittman added the triangular tips to the short wings. If I decide to add the wingtips, I will probably make them out of wood and splice them in to the spars, rather than make a bolt-on weldment. I'm closer to being a woodworker than I am to being a welder :) But the truth is I may also put an engine in it, get it airworthy, and fly it as-is first... then decide if the long wings are worth the effort.
