I have kind of a dumb question,but if I dont ask it then I will not know. When you are building a model whether it is a guillows kit or one that is for rc . What kind of glue do you use to bond everything together really good that wont come apart easily in flight ?? Like I said I feel dumb asking this but I gotta know.

Thank you[8D]

Mainly TitebondII or Elmer's Carpenter for most gluing along with Epoxy for structural places where it's required like firewalls, joining wings, attaching landing gear mounts and the empenage. I also us CA on occasion, but not as much as aliphatic resin.

For balsa to balsa I use CA. Sometimes I use CA on plywood, but for anything subject to stress, such as firewalls and landing gear supports, I use epoxy.

Mostly ca unless i need workign time of wood glue or i need the stregth of emoxy (note only using epoxy would add more wight then needed)

its situational epoxy of course for fire walls and high load areas,CA for a fast tack or when I want to get some progress done, where I know what steps I want to get done and want a fast glue up,mostly thin with a small aplicator tip,and alpfatic resin(tite bond II or III)also for high load areas or where time is not a factor.

Depends on how the build is done:

On wings that are laid down and built piece-by-piece I use Titebond II or III.
On wings that are completely arranged on the board before gluing I tack it all together with medium CA. After removing it from the board I reglue all the joints with Titebond II or III.

Same thing with the fuselage. I always apply a real good fillet in front of and behind all the formers as you need to keep the strength high in those areas. Sheeting the fuselage I always use the Titebond wood glues.

The stabilizer and fin (elevator and rudder if built-up) I piece together the outer frame with wood glue and the sticks I tack with medium CA and reglue later with fillets of wood glue.

I know this is all confusing to some why I do it this way but some reasons are: When you are gluing immediately when laying down the pieces wood glue can be used right away as the glue will be sufficently between the parts. For parts that are laid down first and then glued (some wings, fuselage parts, elevator & fin sticks and some elevator/rudder sticks) I believe (perhaps wrongly) that wood glues such as Titebonds will only coat the outside of the parts and not seep in between - so that is why I tack glue first with CA because I know that glue is wicking in, the reglue with wood glue for strength.

For joining the wing panels, firewall, landing gear plate, stabilizer and fin to fuselage I use either 15-or 30-minute epoxy depending on the time I need.

For installing aileron torque rods I use thick CA.

For installing pushrod tubes I use medium CA.

CA hinges are only applied with thin CA as it needs to wick in really good.

And I always fuelproof the engine compartment with 30-minute epoxy AFTER first painting with a cover-matching paint. You also want to fuelproof the tank area as well (I use 30-minute epoxy for that as well).

Finally I very carefully seal the seam of the covering inside the engine compartment with thin CA to help hold it down against fuel residue (making sure it don't drip onto the fuselage covering)

Anything I miss?

Like others have said, I use CA for most things - Mostly medium, Thin for hinges. And I don't use thin for much else

Epoxy where needed - and I only use 30-minute

Now as far as "wood" glue goes (Also known as Elmer's, Titebond, or Alphatic Resin) I only use it to save on the cost of CA in large areas.

For example: On a larger doubler, or a cap strip etc, I will usually use mostly wood glue, but instead of pinning, I will add a few dots of Meduim CA to hold it in place. That way I can continue to work while the wood glue dries.

All three of these glues are stronger than balsa so their relative strengths are moot. I have been using carpenter's wood glue more and more. It's strong enough and it sands almost like wood. I still use CA for some things though.
