Default need to level horizontal fin...how?

i need to level my horizontal fin because it's not in line with the wing.

I don't know if there is a wire system that i can buy to solve the problem cause i've looked on a couple of sites and i haven't found anything yet.

this is for a UCD .46

Does anyone know exactly what i'm looking for and where to get it?

thanks

First of all, if the horizontal stab is more or less in line with the wing, the plane will fly fine. The UCD is a fun fly plane that is designed to flop around the sky, hover, do tumbling maneuvers, etc. If it is a little "non-parallel", I would fly it first before I make the change. If you decide you must make this revision, I would pry the stab off the fuselage as best you can, sand/cut the fuselage for a better alignment, and then re-glue it using epoxy glue.

A good way to get the stab off the fuse is to use dental floss. I had to do it on my Elder 40. Checked and re-checked, but when the glue set it was not straight. A fellow member at the field told me about using dental floss. It took about four or five lengths of the stuff, used as a saw, but it worked great. Just be carfull as you saw through the glue joint that it stays in the glue joint. Hope this idea works as good for you as it did for me. Good luck & happy flying. The Wine Country Flyer-John

I like the dental floss idea. I'll be filing that one away for future usage. (hopefully it'll be on some one else's plane )

Did you really saw through the glue or were you actually cutting through the balsa? I can't imagine floss having any impact on epoxy.

Believe it or not, it was mostly through the glue. But, as I said, you have to be carefull about your aim and guide it accordingly.
At one point it started into the wood and I had to direct it back into the glue joint. Not really as hard as ya might think. Just saw back and forth keeping your hands even with the glue joint, or up or down as needed. Try it, you'll like it. ---John

trying to cut thru the epoxy with dental floss and then trying to align the stab all over again looked like alittle too much effort so i bought the smallest "I" bolt that i could find at home depot, actually (4) of them and i glued them to the top of the rudder near the upper corner of the LE on both sides and then glued the bolts on each side of the stab towards the fartest corner. Then i cut a 2-56 rod to length put on metal clevis' found the amount of tension i needed to pick up the stab and snapped them on the "I" bolts.

I didn't need the rods on both sides but at least it looks symmetrical.

Problem solved my stab now lines up with my wings and it was a cheap and easy fix. It doesnt look pretty but noones gonna see it in the air.
