When you install the gussets in the fuse at the most aft braces, remember to gut away in the gusset for the rudder cables. Otherwise you will have to do it later with an inspection hole at the rear fuse. Regards, Johann G.

Cut a piece of plywood to fit in the bottom down the middle. Use spacers out of plywood to put between the bottom braces for the big piece of plywood to set on. That way you are putting the big plywood directly on your braces. All little padding under the fuselage between it and the floor would also help. The bottom is curved? I don't understand what you mean, my bottom fuselage is flat as a flitter. While you are there consider "X" braces, it will stop the beer cannoning. The way I did it is on my site, I'm sure there are other ways.

Some wing heaviness will be associated with flying Solo. To eliminate this issue on my first flights, I plan to fly with full fuel on the right tank, and 4 gallons less in the left tank. That will more or less balance out my 165 lb weight. Half way through my flight I plan to switch tanks so when ready to land, will be balanced once again. This strategy should work well for flights an hour or less in length. Even a 1 hour flight (5 gal/hr with Jab3300), should still leave more than 3 gallons useable in the lowest tank at flights end. As someone else has already suggested, another wise precaution before the first flight is to run a level along the bottom of both wings both inboard and outboar of the splice plates. I'm not sure what's a reasonable error for this, someone else may want to comment on this one. In regard to this whole lesson learned thing, would someone out there be willing to keep a database on their websight that provides a list of valuable lessons for everyone to review before their first flight? I can think of a handful of things already: AD checklist (splice plates, rudder petals, engine mounts at the longerons, wheel bearings, etc.) First flight checklist items such as those described above. In particular, safety of flight items such as checking your trim tabs to be sure they are moving the correct direction. Sanity checks for such things as weight and balance and cable tension. What I mean here is what weight would you reasonable expect on the nose wheel for a certain engine just as a double check. flight. The fairlead for the upper elevator cable would be a good example of something we might all want to provide some redundancy for. This stuff can be very subtle, so when someone stumbles across something, it would be great to pass the word along. This is just a thought starter. The recent tragedy reminds us of "How Fragile We Are" and the need to promote safety as much as possibly while still enjoying our dreams of flight!

I considered putting a wire across the plastic ends, but figured the wire better placed in holes in the flange in case the plastic quit on the rivets or cracked or anything else. The wire would work in a pinch with or without the plastic. It doesn't do any work when cables are snug, but if they get loose........ I'd already closed up and had to work from a 4" inspection hole when the wire was added.

Tom Butler N801TB 50 hours ________________________________ Message 15 ____________________________________ Time: 06:10:42 PM PST US From: "Jeff Paden" Subject: Zenith-List: wind --> Zenith-List message posted by: "Jeff Paden" Hello again everyone. I once again could use some input from anyone willing to voice an opinion. As you all know I have been test flying my CH-640 and was very happy until a few days ago. Up to that point I was flying with almost no wind, now that the weather is rolling in I have done two flights with winds in the 15 - 20 kts range. The both of these flights scared the heck out of me as I was not sure that I was going to be able to keep control of the aircraft. The first one was a 20 kts direct cross-wind which I have done many times in my CH-300. However with the CH-640 the aircraft was being tossed around like paper in the wind. Normally this would not bother me, however I did get a little scare when I tried to turn from the down-wind leg to base. When I attempted this the aircraft simply would not turn. I found that I was at full left aileron and the aircraft was not turning. So I pulled back the throttle a bit, pointed the nose down about 20 degrees and was able to force the aircraft to turn left base. The entire time I was being thrown all over the place and the winds really were not that bad. As a matter of fact I flew my friends C-172 and it was very smooth the entire time. I am confused why my CH-640 was being thrown all over the place while his aircraft was able to fly just fine in the same wind. I have re-checked all controls and cables only to find that everything is rigged to specs. Does anyone have any idea of what I should check next? I was thinking that maybe the ailerons needed to be down more. The drawings show them as 10mm down from the trailing edge but when I fly both ailerons are still above the trailing edge in level flight. Just looking for any / all opinions.

In that case the Skyhawk would be about 500 lbs heavier than the 640. That gives the Skyhawk a higher wing loading and a lot more resistance to turbulence and the Skyhawk is built to be more stable to begin with. I don't know why you had so much trouble making the turn to base but the extra weight and stability probably explains the smoother ride in the Skyhawk. -- Bryan Martin N61BM, CH 601 XL, Stratus Subaru.
