Best wood glue for strength but lightweight for profilers?
Since I will begin building my OMP 540 this weekend, I was wonder if any one wood glue is better then another to keep the plane as light as possible, yet have the best bonding out there?
Since the fuselage sheeting will no doubt be glued with standerd wood glue instead of CA, I want to choose wisely.

I like thin CA for just about everything..... Just assemble the parts with nice tight joints and wick in the thin... works great...
Flex for wing to fuse and nose doublers... For joining sheets, I like to tape the joint and use medium CA... I've also used regular old wood glue for this using the same method with good results. Just gotta wait longer...

i like thin CA for framing and any other places it will work (tight fit and accessible) medium CA for sheeting, and 2hr epoxy for wing joint and wing to fuse,epoxy for nose doublers also..
don't know why they make thick CA

For joining sheets of balsa use plan old wood glue! Like Paul said, tape the back side of the wood to keep it even and to keep the back side of the wood clean. Also the wood glue will sand smooth with the wood. I use med. ca for the rest. I avoid thin ca because the fumes burn to much!!

Titebond II
Titebond II works very well, is relatively inexpensive, especially if bought in the larger size container (split with a friend?) and most importantly is both strong AND easy to sand. Weldbond is more flexible when cured but is gummy and harder to sand well. Don't really have any experience with other carpentry type wood glues (except the new polyurethane glues which are expensive and dry like rock). For what it's worth, I've read here and on the old RCO site that Titebond is considered the best of the wood glues... Hope this helps. Cheers and happy building!

I was on a big titebond kick for awhile... I layed up a profile fuse with it... Used it for the sheeting and had some really bad warping... It was really humid and combind with the mosture of the titebond... that fuse twisted like a tornado!!!

Good point!
You're right Paul - when glueing sheets together where larger surface areas are involved you really need to clamp or weight things down until the glue is set and most of the moisture evaporated out of the wood. All that water in the glue has to go somewhere, and my guess is most of it absorbs into the wood as the glue cures.
