Unless you take great pains to make your cabin air tight, you will have plenty of places where air will exit, such as the seam where the canopy meets the side of the cockpit and the hole through the spar for the rudder cables and wiring. Getting air to exit shouldn't be a problem. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Airframe construction complete. Panel and engine installed.

Before I go beyond the point of no return, can someone clarify whether the dimesions on drawing 7-V-9 for wing tip trimming are meant to be the cut lines or the rivet lines? < Hi Larry, The 7V9 drawing indicates the cut line. Before you put shears to metal, its a good idea to buy some heavy Bristol Board and cut the dimensions on that, fit it to the wing, tape it and fiddle with the exact dimensions, then transfer that to the metal. Now you will have an accurate fit. I used this technique thruout the building, especially for the wing roots (I ruined several), and any curved or fiddly parts. Everyone builds differently, and the plans quite often lead you astray, so stay one step ahead by reading and understanding the plans way ahead of the parts you are working on. On the wing tip one area to watch for is the bottom wing skin at the wing tip. If 7v9-1 is a little off, you will distort the bottom skin upwards in this area, so keep 7v9-1 loose and accurate.

But what helped the most was the single computer fan I placed between the IP & the front edge of the canopy. It's mounted flat over a hole I cut in the top fuse skin about 3" in dia. When turned on you can really feel the breeze going up the front of the canopy and past your head. I had a situation one humid day that caused my canopy to start to fog up. After turning the front computer fan on the canopy cleared off in 10 seconds. If both front & rear fans are turned on and the side fuse NACA vents open that long hot taxi to the runways not so bad.

Trial and error, here's what it should look like: http://home.comcast.net/~bryanmmartin/index.html The crimps you can see in this photo cause the angles to curve to match the airfoil shape. The crimps in the other edge of the angles that you can't see in this photo cause the angles to curve to match the edge of the wing skins. Closely spaced crimps where the radius of curvature is small, less closely spaced where the radius is larger. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru. Airframe construction complete.

And on a different note. I found a correction in the, "updates to the 3rd edition" today. This was never corrected in the 4th. ed. that I'm building to! Or even mentioned in the "updates to the 4th. ed.! Now they are right back where they started. ________________________________ Message 10 ____________________________________ Time: 06:23:15 PM PST US From: Rico Voss Subject: Re: Zenith-List: 601XL 6W9-7 Crimping the Wing Tip End Angles --> Zenith-List message posted by: Rico Voss >construction > manual says crimp every > 20mm on both sides of the piece. This is getting me > NO WHERE near the right > angle. Gig, You is right, that's a definite hair-puller, especially the top side, which has a compound angle. Remember that the bend will be formed in the flange OPPOSITE to the one where you put the crimps.. Like Bryan said, it's trial and error-- takes a lot of adjustment. Also, be sure to co-ordinate the crimps with the hole drilling in the skin, so you dont pre-drill into a crimp void, like I did... And for J.Birgiolas on "701 Wing Tips", (for cutting the end of the wing skin): On the XL, I found the table of coordinates in the plans to have questionable value. I used those numbers for roughing in, then I bent and clamped a piece of thin wooden dowel (1/8, I think) to fair in the final curve back to the aileron. Your only fixed points are the spar end and the rear-channel end.
