''1-it's bad for your health ''
When taken internally.

The vapors alone are bad enough... don't kid yourself
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.

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.

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.

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.

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.
