My complaints with the formula 560.
..Runny
..Yellows in sun light
..Two slow to tack up and cure
..Week
..Doesn’t adhere well to monokote
..Still creamy looking when dry
I have been thinking of using clear silicone.
I only use CA or clear silicone for installing my canopies. I use CA if I am going to paint my canopy deck, and silicone if I am just placing the canopy on a Monokote covered deck. I do this on all my airplanes, both always work really good for me.

RE: Is any one using weldbond glue?
The first CA I can remember in the RC field was in the early 70s and the name of the stuff was "Hot Stuff". A thin wisp of smoke or vapor actually curled up when this stuff worked. I actually saw a guy break a fuse in half, glue it back together and fly it again in the space of five minutes or so. 1972?

Yes as LesUeda said "When taken internally" .
The better solution is to avoid using CA.
It is not strong as other glues in most applications due to the way it is often applied. .
It needs very accurate fitting of the glued surfaces.
It shrinks too much while curing.
It does not provide for a larger binding area (filleting of the glue).
Why use an inferior product that also happens to be more healh risks ?
Good old wood glue: Seg-Ment, Titebond, Weldbond, Lepage and similar is preferable for overlall wood gluing. Even fiewalls and landing gears can be using these glues with corner reinforcements.
Like someone says "Glue it all together and sand away what does not look like an airplane".
I love that statement.

I'm not really sure how to define "bad", but I've been using the stuff since it came out in the mid/late ??? 50's. I am now 80 years old, and had suffered no ill effects that can be traced back to that, only to my 40 or so years of smoking.

None of what you state about CA is correct, with the exception of precision joints and I demand that anyway. I have done many build threads over the years, some featuring 40 to 55% aircraft and other than the sheeted parts that I now only use epoxy and vacuum on, I only use CA on my airframes, even on the motor boxes supporting 200 cc engines and landing gear assemblies with no glue line failures. In fact, I built a manned ultralight utilizing only CA as the glue, and a 425 lb. RC aircraft that the fuse and tail feathers were assembled with CA, some may remember the 70% Staudacher, well thats the one. So you see, if used correctly, CA is a very good choice. I build in and open door garage, so the smell of CA never really gets to me.

RE: Is any one using weldbond glue?
Very well said sensei.
I too am a fan of CA for general construction (see my first post in this thread, where I was called "Silly"). With CA you can use less than 1/4 the weight of wood glues, and achieve much greater strenght at the same time. This assumes proper fitting joints of course.
Glad to see I am not alone in my building.

RE: Is any one using weldbond glue?
I have taught many builders how to build utilizing only CA for there structures, Aerotech RC now offer couple of my design giant scale hyper light series kits that are based on building using only CA on the structures. I have also been building 40+ years and had to use the old glue, pin, and wait overnight game. boy am I glad those days are gone...

Hello Bob,
Any pictures of the models you built (40% and 55%) ?
Any links to the build threads ?
It would be valuable information for all readers.
Particularly for many who build in the winter in closed premises.
It is not the "smell" it is the "vapors" inhaled that are part of the situation.

It's not easy to to convey a thought on these forums, when you have someone with a "savant syndrome", to put it mildly, (yes zor, check the def. in wikipedia) distorting everything one says.[:'(]
Vapors don't HAVE to be taken internally to be damaging. They can be irritants to the eyes, skin ... externally. Which CA glue has been observed to be. Just to make things clear

Sure, there is a build thread here on RCU called 40 % 260 on a diet of my Carden 260. You will need to goto FG to see the build thread on the 55% Extra 260 and the 52% Extra 300 SP. http://vimeo.com/22492765
You can see the 55% 260 if you google and type in Joe Nall 2010 noon demo 1 and if you wish to see the 70% Staudacher video google 70% Staudacher. here are a few pics.

RE: Is any one using weldbond glue?
Hi Bob,
Thanks for the few pics.
I am on my way to find the other avenues of admiration as per your instructions.
Anyone said that building is out of fashion ?
Many of us are still building models whenever time can be found.
Thanksk also for the directions to the sites Bob.

I'm not really sure how to define "bad", but I've been using the stuff since it came out in the mid/late ??? 50's. I am now 80 years old, and had suffered no ill effects that can be traced back to that, only to my 40 or so years of smoking.
