By manufacturing problem, I meant build/installation problem. One thing pointed out to me by some aeronatical buddies is that maybe the stabilizer needs to be stiffer. They said if the stabilizer is not as stiff as the elevator and when loaded it is flexing more than the elevator hence causing the hinge to fail.
One question on the hinge points is that since it is a stick build up stabilizer the hinge point is longer than the the stick is wide so some of it won't be glued in. Is that a problem?
I was going to install the hinge point at the very end since there is wood there. Is that a problem? MINN you said put it in 3/4".
Another question is how many hinge point do you recommend I install. The are a total of 4 CA hinges holding the elevator on, but was going to install 6 hinge points. What do you think?
Last comment, Campy you say that the wood will tear before the CA hinge, well this is not what happened. Twice I have had the CA hinges tear at the gap an no structural damage has occured to the wood that they are in.
Thanks again for your help
