Hi group! - Last weekend, I went to Les Faucheurs de Marguerite, one of the biggest fly in we have around here.- They got 3000 visitors this year.- More than -200 aircraft went to the "rendez-vous". - Flying there was OK despites poor performance due to temperatures and humid ity.- On my way back, the engine went rough a few times.- I decided to fly IFR ("I follow roads") just in case something goes wrong.--Just as I was approaching CZBM, 25 minutes away from my airport CSB3, it went rough again... I told my passenger (who did'nt notice a thing) that we will do a stop in Bromont; he said "COOL!".- I climbed to 3200 feet and flew over the airport.- I decided to do the approach as if I did not want to rely o n the engine for final approach.- That went very well (I practice forced landings often when I fly alone - approaching and landing on idle). - Once on the ground, I turned the prop by hand and could hear a "click" in t he engine at every four strokes... yark!- I decided to leave the plane th ere.- My wife took a car ride to get us back and Thursday, me and a frien d put the plane on a trailer to bring it back. - I decided to stop maintaining the Soob engine.- I have a brand -new Fra nklin in my garage since more than 3 years and I don't work enough on it... now that my plane is dismantled, I hope it will be easier to find the time .--- This weekend, I built a box to store and protect the wings (good first step). - So; not a pilot for a while; back to be a builder. - do not archive - ps: if I can find how to update my web site; I will (but I don't have Front page anymore so it might take time). ---------------------------- Michel Therrien CH601-HD, C-GZGQ http://mthobby.pcperfect.com/ch601 http://pages.infinit.net/mthobby -=0A=0A ________________________________ Message 3 _____________________________________ Time: 06:05:30 AM PST US From: "ella" Subject: Re: Zenith601-List: 601xl down Hi What is the difference between a 601 xl vs 601xlb Thanks don ----- Original Message ----- From: N601xl@aol.com To: zenith601-list@matronics.com ; zenith-list@matronics.com ; zenith650-list@matronics.com Sent: Sunday, July 04, 2010 7:20 AM Subject: Zenith601-List: 601xl down a 601xlb crashed around frankfort ky. around the end of June Has anyone heard about this?

Looks like I'll have to move it forward somewhat (2 or 3 cm), and perhaps add a little shim to the rear attachment, so the width looks ok. My question to the group is about edge distance: the (CH601-HD) construction manual (Edition 3, Jan 1995) says, in the "tail installation on the fuselage" section (page 26): "watch for a minimum edge distance of 13 mm to any edge." While the dimensions of 6F2-7 and -8 (6B3-3/4 on the XL) allow for this, 6T2-1 and 6T2-3 do not - or at least I don't see how. Therefore, I am assuming that the 13 mm statement refers to the HT attachment brackets only (6F2-7 / 8 on the 601-HD and 6B3-3 / 4 on the XL). I would appreciate the group's comments on this. Thanks in advance Carlos CH601-HD, plans ________________________________ Message 9 _____________________________________ Time: 05:34:31 PM PST US Subject: Zenith601-List: Re: Solid rivet confusion From: "Tim Juhl" Thanks for the info... I appreciate all your comments. I was planning on using a mix of rivets and bolts, assuming I can set the rivets OK with my 3x gun. I haven't a lot of experience riveting (took an EAA class) and plan to set up a practice jig to see how it goes. I did buy a 5 lb bucking bar which I understand should help. The features that attracted me to the XL in the first place haven't changed. My hope is that experience with the modified aircraft will allow all of us to fly our planes with confidence as long as we stay within the envelope, which is true of all aircraft. I didn't mean to rekindle old arguments but we all know that we'll have to wait for some time to pass to get our answers. Happy 4th of July!
