Page 10 of the 6 ZU-4 says to square the ribs holding the counterbalance and flat on a surface. Then back drill the inboard rib. If the hole is drilled square to the hinge line then when they are skewed to be parallel to rib 3 shown earlier then the holes will not line up. It cost me 2 new ribs and a counterbalance tube. if I am wrong about this let the flames begin! They said they were going to change the photo but as of yet it has not been changed. bobby ________________________________ Message 2 _____________________________________ Time: 09:50:21 AM PST US Subject: Zenith601-List: New 601 Upgrade Drawing Revision From: "DaveG601XL" There is a new Zenith upgrade drawing revision out there dated January 25. http://www.zenithair.com/news/ntsb-astm-4-09a.html I wish they would publish a revision history with these. It would save us from a "Where's Waldo" exercise of having to find the changes. Unless someone sees more than me, this is what I see different from the last December issuance I had. 6ZU1: Lower left, reference to A5 rivets in 6ZU1-4 and 6ZU1-2 6ZU2: Upper middle, reference to torques on NAS bolt/nuts. These are just a bit higher than the AN torque values. 6ZU2: Upper right, 6B13-2 thickness check. 6ZU3:Lower middle, reference to a cut-out, if needed, in 6ZU4-1 for control cable clearance. -------- David Gallagher 601 XL/Jabiru 3300 First flight 7/24/08 116.5 hours and holding (incorporating upgrade) Read this topic online here: http://forums.matronics.com/viewtopic.php?p=284854#284854 ________________________________ Message 3 _____________________________________ Time: 10:22:56 AM PST US Subject: Zenith601-List: Re: Counter balance snag in the LAA drawings From: "Ron Lendon" I think the confusion comes from using the Zenith supplied User Guide. If you follow the actual LAA prints it should work out much better. This one caught me also and I canted the ribs to gain room. I will find out tonight if that will fix the issue. -------- Ron Lendon, Clinton Township, MI WW Corvair with Roy's Garage 5th bearing Zodiac XL, ScrapBuilder ;-) http://www.mykitlog.com/rlendon Read this topic online here: http://forums.matronics.com/viewtopic.php?p=284858#284858 ________________________________ Message 4 _____________________________________ Time: 11:12:21 AM PST US From: Davcoberly@wmconnect.com Subject: Re: Zenith601-List: Aileron Counterbalance I had the same problem. I didn't think about it at the time when I couldn't figure out why the forward part of the outboard rib wasn't touching the forward part of the aileron then I thought about squaring the ribs then cocking them at an angle no wonder they weren't fitting. I had to put doublers on my ribs and reversed and turn 90 deg my arm to keeping from having to buy new ones. Also the latest revisions have two more angles for the #1 nose ribs that weren't included in my kit. Plus several other changes that most I had already figured out on my own. These are dated 1-25-2010.

Roger didn't follow the drawings and placed his at 90 degrees so he had much more room from the wingtip. If you look at the photo guide you will see in his aileron the bottom rivet line is very close to the trailing edge outboard tip. If you use the LAA drawing measurements it is further away thus putting the tube closer to the wing tip. Jeff In a message dated 2/4/2010 2:17:36 P.M.

The outboard 2 weights hit the rivet line. We also discovered there was only 82 mm down travel from neutral even if the tube clears the rivets. Plans call for 85mm. I still have the 97 deg. shown on the drawings on my protractor and will lay it out and raise the angle to move the end of the tube up 10mm ( which ain't much ). We measured a total of 197mm between the bottom skin and the top so there is enough room for the 170mm total travel but it will have to be centered very precise. Only about 13mm top and 13 on bottom clear. Has anyone tried to bend the 3/4" square tube after it has been riveted in place?? bobby Jacksonville, Florida ________________________________ Message 7 _____________________________________ Time: 04:27:19 PM PST US From: Afterfxllc@aol.com Subject: Re: Zenith601-List: aileron deflection You can bend the tube the same way you do the canopy tube. .. Place 2 bolts on one side and one bolt in the middle of the 2 bolts on the other and put in a vice and it will bend. Extrusion is brittle and really not supposed to be bent so go easy.

The fix I am going to apply is to bend the arm about 2.5" towards the fuselage. It was EAA chapter 13 night and some good ideas came out about how to move the bar without tearing the aileron down again. Going to make a form to make the bend that will keep the bar boxed while forming with clamps.

Then it fits without bending the tube. Jeff In a message dated 2/4/2010 11:50:18 P.M.
