YES --> Zenith-List message posted by: Fritz Gurschick ( I sent the following reply to Gary, than thought it best to share with the list) HI Gary ----- thanks for the reply--------- please notice that because of the great replies I infact have changed my mind and agree that "full throttle at linkage breakage" is the way I'll go, when I get the engine set up in my 601 XL. ( I am planning on using the "William Wynn corvair conversion".) My 701 ( which I no longer own) had good, hydraulic brakes, and was powered with the Rotax 582 (2 cycle) engine. This engine would rev up real quick and would actually drag the wheels with the brakes on. My friend's 701 on the other hand had the Rotax 582, and his airplane had very poor, weak, mechenical, drum brakes this is why he recommended I not go with the "full throttle at linkage breakage" set up in my 701. In his airplane, this set-up could have been very dangerous. Thanks for writing, again I have changed my mind and agree with the "full throttle set-up at linkage breakage"------- Happy flying--- Fritz do not archive Gary Gower wrote: --> Zenith-List message posted by: Gary Gower Hello Fritz, The spring to full power is very important.

I have an 801 and even at gross weight with Zenith-supplied plastic brake lines I have no trouble stopping. Before the break-in I could not keep the plane from creeping forward during 1900 rpm mag tests. The polypropylene lines supplied by Zenith are very hard, unlike many other plastic types. Another potential problem leading to insufficient braking is the presence of some air in the brake lines.

This might be a stupid question, but when you turn over the wings and cleco top skin on the inside. Then turn over and do the bottom skin when you go to rivet bottom skin on skeleton, how do you remove the clecos from the inside on the top skin.

I believe their exact phraseology was to the effect that you want your best work on top (where it's seen). At any rate, install clecoes on the outside of all skins. That means you have to be careful if you intend to lay the wing down on installed clecoes. Be sure to Einstein a method of having something to support the wing between the clecoes. Gary A.

I left the clecoes outside the top skin and just used more steel tubes under the spar and rear channel to get the proper angle on the spar and make sure the clecoes were clear of the table. This is pretty fresh, since I did just that today! I am working on the left wing with the right one complete and in storage. Another trick I developed to align the nose ribs. Once the spar edge of the nose skin has been clecoed, I slip a 1 x 2 between the skin and just above the nose of the rib. That way, I can drill a pilot hole (the last one toward the nose) without drilling thru the rib flange. Then I can align the centerline mark on the rib flange thru this pilot hole. Works every time.

There are two jigs used, one for the bottom alignment and one for the top gap. But when I have the bottom set correctly there is too much gap at the top. The bracket on the wing hits the slat and I can't get them close enough together to meet all the specs. There is supposed to be a 16 to 18mm gap between the top of the slat and the top of the wing. But the closest I can get at the top is about 21mm. All 8 brackets are about the same. I have already filed down the tops of the brackets so that there is a 10mm radius around the top hole. Anyone hit this problem? Any suggestions before I send ZAC a note and ask if I can reposition the mounting holes and cut down the bracket (or just have a 20mm gap at the top)?

Out here in the boondocks, we can get 6x6 roughcut blocking for next to nothing (If not nothing). Very nice being able to set or pull clecos without having to re-level everything.

On the second wing, which looks better than the first, I did the final rivet on the top skin before I even drilled the bottom. They say you can do some straightening by tapping on rivets but I didn't find that worked well. Use a small square to make sure the rib flanges are at 90 degrees before you start or the flanges will pull your skins out of flat. On my next 601 (((NOT))) I will do everything better and faster! Make sure your table is flat w/ a level.

When I do wing skins, the clecos go on the outside rather than the inside. The only ones on the inside are in places that will always be accessible like the baggage compartment. Paul XL wings.

The wing nose skin slightly bulges out on the bottom where it bends around the nose ribs. This slightly moves the jig on the bottom lower than shown on the plans. Look at how the brackets on the slats and the wing come together at all 4 points. There is a natural fit to these. If the slat brackets look like they are sitting alot lower than the wing brackets this is due to you trying to align the slat grounded to the jig. This will work on their drawing but in reality I found it will not work. The drawing is basically showing that if you set the wing on a table with the slat attached, the slat edge will touch the table. In reality the slat edge will sit slightly higher than the bottom surface of the wing. I got 18 mm between the top of wing and slat. Do not cut your brackets or reposition holes. I did round off the top as you did a lso. You used separately made jigs to carefully position these brackets on the slat ribs and the wing nose ribs. They should line up pretty close in the final assembly.
