I'm just venting, not looking for advise:
I ripped the vertical stab off of my rummage-sale Skyray and put a new (non-offset and non-warped) one on in time to fly the 1st. It flew very well, but at the end of the day as I cleaned the plane the thing snapped right off!!! It's way cold in my shop and I used 5-minute epoxy rather sparingly, so either there just wasn't enough glue, it didn't harden properly because of the cold, or some combination of the two.
@#$%. Got it home, sanded everything flat, put it back on with 30 minute epoxy this time. In the process I noticed that in my hurry to get to Delta Park with a flyable airplane I had put a cutting mat on top of the rubber power model that was displaced to make room for the Skyray work -- I bent it's vertical stab over 90 degrees. Argh. So, let the Skyray sit out in the shop for two hours, then decided that I should put it somewhere warm to finish up. The glue was firm, so I took the clamps off, hung it up in my office -- a couple of hours later I notice that the stab has fallen off.
%$@#. Peeled the glue off (it hadn't set completely), redid the whole thing, hung it up in my nice warm office with the clamps on. Guess what! While the clamps were plenty sufficient to hold things straight with the plane upright, they weren't enough to keep it straight while hanging. @$#%, *&^%, @&$% and *@#$.
So, once again, I need to clear the indoor rubber model off the bench (carefully), cut the #&^$ stab off, and do it again.
Some people build well because they're good. Some people do as well as they do because they're pig headed.
Oink.
