Hello,
 
I am trying to locate the rear channels in my 701 wing skeletons.  I built a template which seems to measure correctly, but it seems to have placed the rear channels about 3-5 mm too far toward the trailing edge.  When I place the flaperon brackets, they do not correctly align with the top or end of the rib.  Also, the forward edge of the flaperon bracket is not parallel to the rear channel, as the drawings suggest it should be.  It appears that the template positions the rear channel too far back, even though it seems to measure correctly. 
 
If I move the rear channels forward about 4-5 mm and clamp them, the flaperon brackets fit fine and are positioned properly with respect to the rear channel.  Unfortunately, I have already drilled the holes for the rear channel to rear rib connection.  It seems that I can either use the flaperon brackets as a guide to shift the channel forward, making new rear channels and attachment brackets, or I can use the current positioning and “file to fit” on the flaperon brackets, which really has no appeal.  I am also concerned about rivet edge distances if I modify the flaperon brackets.
 
Any suggestions or insights are welcome.  I was quite careful with template construction and positioning and am at a loss as to what to do next.
 
Thanks in advance,
Chuck Kyle

I don't know if you are building from scratch or a kit but make sure if you have predrilled holes in the wing skin that they will line up with the channels. You can easily make new "L" brackets (larger if required) that hold the rear channels and reposition the rear channel to it's correct location. My flaperon brackets required a little trimming to fit correctly. I would spend the time and reposition the channel to the correct location.

I had no problem with the template, although I spent a lot of time checking the measurements on the front of the template
