REFLECTOR: Correct wing measurements

[Jack Prock]

Hey Andy,

Thanks, I did see where the manual says one thing, but then the drawing shows another. 

As for the DVD versus the manual... my kit is  three years old, though new to me as of six weeks ago, and 
I have VCR tapes. I don't think they have redone the training videos, but ya never know. I will have to watch
that part of the tape and see if I can tell what you are talking about. 

I would love to see the pictures. I am kind of a velocity plane junkie at this point, I think I have
perused every Velocity building site out there. I'm always looking for helpful hints.

  I just looked at the KCP's and it hasn't been corrected yet. Read the text very carefully, it states that the X measurement should be taken down the leading edge of the spar. The picture showing the X measurement being taken to the tip of the wing is what is shown wrong. If you lay the template on your wing with the X measurement down the forward edge of the spar, it will fit your wing. Another thing that I did to make the measurements a one man job was when I found the C/L of the outboard attachment bushing, (per the manual where all X and Z measurements are made from) I drilled a very small hole on the top forward edge of my spar, and installed the smallest finish nail that I could find. This allowed me to make all the measurement by myself, and to make sure that all future measurements will always be from the same place. I also had trouble with the winglet trim template. I never did get it to fit just right. What I finally did was to attach my wings to the spar and with every thing correctly leveled, I held my winglets at the correct angle and location and marked where it should go and then used the template to check what I marked. The template says to line up with a foam seam that doesn't exist on the newer winglet billets anymore. Save the foam that you cut off of your winglets for the foam fill needed for lay-up C. When you do lay-up C watch the DVD on how to cover your rudder bell crank. I think this is a better solution that what the manual states. If you follow the manual all of your lay-ups would be forward of the bell crank reducing the lay-up to a width of about 15 inches. If you follow the DVD, all of your C lay-ups cover everything forward of the rudder adding at least 5 inches more strength. I have everything almost ready for this lay-up and could post some pictures or send them to you directly if you are interested. I know a picture is worth a thousand words.

    Do you know if this has been corrected in the manual? I am a about to do this in the next few weeks and I would like to know if
    there is still something to watch out for.

      Since the subject has come up on flutter and the measurements that are needed to check you winglet toe-in is very critical, I thought I should add something that I found building my wings. I was to the point of needing to trim my wings for the winglets that I noticed that I couldn't get the template to line up as the manual suggested. I took several pictures of the problem and sent them to Velocity and asked what I was doing wrong. What was determined was that the picture of the X measurement was shown wrong in the manual. This measurement should not angle out to the leading edge as shown on figure 2-25. This X dimension should be measured straight down the leading edge of the spar. This correction came from Scott Swing who stated that the manual would be updated to correct this issue. If you make the X and Z measurements correctly, you will have very close to the 1" winglet toe in that you need. I just tested this last week when I attached my winglets.
