RE: Magic Hand 73" yak build thread
Horizontal stab:
I installed the horizontal stab this morning. I have attached some pictures of how it went.
First I cut the covering from the stab opening and also the elevator servo bays. I then dry fit the stab and measured equi-distance out from the fuse at the rear of the stab. I also mark the center line of the fuse at the front and drive a T-pin in with a string attached and measure the distance from there to the stab tip to make sure they are equal. I then traced the outer edge of the fuse opening and pulled the stab out. Using an older soldering gun in trimmed off the utracote leaving 1/8" on the inside. I refit the stab and checked the angles I then leveled the fuse both laterally and longitudinally. Once I had a level on the canopy opening I checked the incidence of the stab. Once satisfied I mixed up some 20 minute epoxy and glued it in place, rechecking all the angles.
The only issue I had is the incidence changed once the epoxy dried from 0 to -1 approx. I was a little bummed because I wanted 0 across the board and there is really no way to tear it all apart to change it. So I will make the best of it. (I am only assuming 0 is correct as there are no incidences in the manual) Note: the stab opening is big and there is some space that will need to be filled. Once I had the stab in place I put a small amount of thin CA in the front to hold it in place.
