Is there a sheet in the drawings or a page in the "Photo Assembly Guides" that describes how to this? It looks like 7V10 shows a 75mm dihedral. How do I set the incidence angle? Is the top of the horizontal stab, bottom of the wing, and the reference E-A line (7F15) all parallel? I assume that the forward edge of the right/left wing are aligned (no swept angle).

I think it entailed drilling the forward holes for the wing spar then leaving the drill bit in place. The rear posistion was set with a string above the main spars by lining them up. -------- CH 701 Read this topic online here: http://forums.matronics.com/viewtopic.php?p=259951#259951 ________________________________ Message 3 _____________________________________ Time: 09:12:12 AM PST US From: MacDonald Doug Subject: Re: Zenith701801-List: Fitting wings to fuse Hey Curt, I have to agree that the plans are a little vague in this area. I just mounted my wings in the last month and had to do some real head scratching to come up with a plan. The fisrt step is to set up your rear spar mount. The fit of the inboard end of the training edge against the fuselage kind of sets where the wing will live. Once you have the rear of the wing located, run a string down the spar line to eliminate the forward or rearward sweep in the wings and set the dihedral. I am at work right now so I don't know which page it is on in the plans but there is a diagram showing this and some other information there (not a lot). The incidence angle seems to be set by the location of the front and rear spar mounts and there is not a lot of adjustment there. To set the dihedral, level the fuselage and measure up the the spar string at rib #1. This distance should be 75mm (if I remember correctly). The biggest advice I can give is don't drill any of the spar holes until you are sure that everything is as close to perfect as you can get it. Start out with a pilot hole of 3/32" and drill out to 5/16 in stages. It is possible to make minor adjustments as you drill the holes out to final size but not a lot.

If they are even a little it will act as a propeller and you will end up with a heavy wing. I use a four foot level with a stand off. I leveled from the main spar to the rear spar and adjusted from wing to wing until they were identical. When all was right I clamped and drilled. -------- Ron Lee Tucson, Arizona Read this topic online here: http://forums.matronics.com/viewtopic.php?p=259965#259965 ________________________________ Message 6 _____________________________________ Time: 10:34:11 AM PST US From: "Curt Thompson" Subject: RE: Zenith701801-List: Re: Fitting wings to fuse That was useful but didn't answer my question about incidence angle. It seems to me that the angle of the horizontal stab to the wing would be important.
