I am ready to build my engine mount for my 601 .I will be using either my newly purchased 0235 Franklin or my 0200 Cont. (they both fit the same mount). I have been studying the plans but I could use some more help .Could anyone on the list send me a picture of a completed 0200 mount or perhaps a cad drawing showing a 3D view . Thanks Wade Jones South Texas 601XL plans building Cont. 0200 ________________________________ Message 2 _____________________________________ Time: 05:46:37 AM PST US Subject: Zenith-List: Re: A Christmas Story From: "Tommy Walker" Thanks for that Gig....

After takeoff, he noticed it due to the noise. He attempted to pull the right side down and latch it securely. This guy is about 6 4 and is a bear of a man. He said he couldnt get it down, so he decided to loosen the left side so that he could level the canopy and then pull both sides down and close the latches. Big Mistake. He said the canopy immediately went to about 45 degrees and he entered a steep dive. He was able to reduce power, level off and gain control over the airplane. At full power, he was not able to climb, as the canopy acted like a speed brake. At full power, he headed back to the airport at his present level and was able to land. He said everything that was unsecured (insecured?) err, not secure, in the airplane departed, including extra headsets, gps, log books, etc. Regards, Tommy Walker in Alabama N8701 18.5 hrs P.S. Please don't take this as criticism of the 601 design. The PIC is responsible for making sure the canopy is secure before takeoff. [quote=" www.evektoramerica.com/SportStarPlus.htm The canopy popped while we were in the pattern. I would estimate that the gap was well over a foot. While the instructor flew I tried to close the canopy. I wrapped my arm around the cross-bar and used all my weight and strength and could not close the canopy. At best I think I got the gap down to 6-8 inches. Evector redesigned the latch the next year. I believe the upward force was generated by lift and not wind under the canopy as it did not decrease as I closed the gap. -- Craig[/quote] -------- Tommy Walker Read this topic online here: http://forums.matronics.com/viewtopic.php?p=154165#154165 ________________________________ Message 4 _____________________________________ Time: 07:14:18 AM PST US From: "Iberplanes IGL" Subject: Re: Zenith-List: Re: Canopy Gas Struts (Springs) To all of you, BSCL : BEFORE START CHECK LIST.

In those areas the wall gets thicker because the outside is curving and the inside walls are flat and parallel. The drawn tube is just like circular drawn tube except that the section is similar to streamline steel strut tubing (very nearly constant wall thickness). When you make the attachments for the end fittings they need to be shaped like the inside of the drawn tubing or some consideration given to stability of the joint. Hoe that is clearer - I may not speak the same english! I don't understand "pad" and flat on parallel" Kevin Quote: "Also the drawn tube does not have the "pad" on the inside making flat an parallel mounting interface - you will have to create something to affect the same result." -------- Kevin Read this topic online here: http://forums.matronics.com/viewtopic.php?p=154262#154262 Dave Downey Harleysville (SE) PA 100 HP Corvair --------------------------------- Never miss a thing.

Not to me. I have confidence in the design and the designer. If there are some that would like another layer of security, this country boy -- clodhopper humbly offers the suggestion that one could construct their top and bottom wing skins with the next heavier sheet size. It would add a small increase in weight but would stiffen up the structure somewhat. Many builders are now doing this in the fuselage without a second thought. Another way to stiffen the wing would be to add drag braces internally like a rag-wing. Even I don't think much of that idea.
