I am considering buying a stick built airplane. The trouble is, it has sat up in the owner's garage for about 10 years without flying. I am wondering if the yellow carpenter's glue he used to build it is still strong. Does it become brittle or weaken over time? I am concerned the flexing that will occur while I am flying it might cause the glue joints to break because they have become brittle over time.

I have a 25 year old "Spook" that was built with yellow glue and it's strong as ever. The main thing......as with everything else, inspect the joints and you can tell for the most part the condition it's in. If it were CA adhesive, I'd be a little more concerned. Bob

Bob,
Thanks for the info. The airplane was built with yellow glue by an very good builder. The only concern was whether the glue had deteriorated over the years. If you flying a 25 year old plane the 10 year old glue should be good. I will check the joints over really well, though.
Thanks again.

All's fine. Yellow glue best. I wonder if the ARFers ever considered the same. Oh wait, they use ARF glue.

Not from all the complaints I see around here - they don't use ANY glue...[X(]

That's why I build my own.

Wish I'd said that Bob

Well now, it is really good to see that someone recognizes that the modern day modeler has
time to do everything else, BUT build his own plane thanks to the brainwashing done by the mfg's. By the looks of the ARF's at my clubs flying field, there is no need to up grade any part
of the model even though safety improvements could be made. Just rebuilt a cheap ARF that
a member gave away after the crash, and I am amazed that the crummy "Z" bends for the servo arm actually stayed in the holes besides not binding so much that the servo did not stall.
Maybe that is why a servo stripped out some gear teeth causing the crash. I find it interesting
to read that CA has an age life. Where can I read more about this problem? It is correct that
the glue guns do not always put glue on the parts during ARF manufacturing. I am wondering if
these are suppose to be confettii models that come apart during some high altitude maneuver
with all the wood floating down.

Yes, it is true that some don't have any glue. I've seen hot glue on a UCanDo.
