Zen 50 NEED HELP.

My Feedback: (13)
I bought a used Zen 50, here is my problem.
The stab is loose. It slides through the fuse, now that the elevators are on it will not come out so I can re glue it. How should I go about fixing it?
Should I try to remove the elevators so I can pull it out. Or should I find a way to insert more glue?
I thought about inserting some dowls down through the fuse and stab but I do not know how sturdy this will be.
Another concern is If I just try to re glue it, there might be fuel residue in it that would keep it from adhearing. I'm anxious to get this flying but I'm not sure how to go about repairs.

Cut 3mm of film away on the body around they stab and do the same on the stab where it meets the body.
Make sure everything is straight and true then drop some ca in the joint to lock it into position.
Mix some 30 mine epoxy and micro ballons and dribble it into the joint. Take a wet finger and run it over the epoxy to form a fillet.

bla bla has the best way to keep the weight down!!
Just to add my 2 free cents, make sure you correctly position the horizontal stab. Measure the distances to the wing tips and fuse center line.
If the stab moves vertically, make sure the pin them down perpendicular to vertical stab and correct incidence.
Good luck,

Here is how I did it. I would recomend doing this on intitial construction as well, if you have a very tight fit of the stab through the fuse.
I pulled back the covering, and about 1/2 " above the stab, drilled a hole. The hole needs to be the size of whatever dowl you have laying around. Mine was for a 3/8" dowl.
I lined up the stab where I wanted it and put a few drops of ca to hold it. I mixed up some 45 min epoxy, and poured it in the hole. Then rotated the fuse until the epoxy started to ooze from the gaps in the joint. I also added some heat by means of my wifes blow drier to help the epoxy flow. Then blug the hole with the dowl. Since the stab is supported by the sides of the fuse (the stab is airfoiled, and there is no mounting plate) The epoxy made a good joint.
After that cured I did the same on the bottom.
I would also recomend removing a little more covering from the stab then what is already gone. It looked like there was at least 1/4" to much.
One caution be sure the epoxy does not get on, or in the way of the elevator pushrod.
Anyhow I now have a well secured stab. Thanks for the help, and hope someone can benifit from my experience.
