Default Glue recommendations please?

Can anyone lead me to a discussion or some type of chart/guide that pertains to glue usage? I'm getting ready to build by first kit (CG Eagle II) and want to do it right. I've read the build instructions, and it's not clear to me what is the best type to use. The book references several different types. I've had several club members make suggestions, but they don't seem to agree on what would work best for a begginer. Some suggestions are wood glue, epoxyies, elmer's general purpose, elmer's ultimate, CA slow, med. and fast set, Gorilla brand, etc. Thanks, Todd

You've already found your answer, there is no one "best" kind of glue. Each of the adhesives you've mentioned has its advantages and disadvantages. Each is best suited for a particular task. Which adhesives you choose to use and how you apply them is part of the "art" to building your kit.

A quality carpenter's glue or wood glue (Tite Bond, etc.) is non-toxic and will provide strong, lightweight joints. Epoxy is heavy, but will provide very strong joints in critical areas like when attaching firewalls or joining wing-halves. Epoxy can also be thinned with denatured alcohol and used to fuel-proof area of the plane. CA glue is lightweight and very strong, but its toxicity makes it hazardous to work with unless particular attention is paid to ventilation. CA will be valuable in areas where instant setting is helpful (thin CA) or where a less-than-perfect fit prevents wood glue from creating a strong, reliable joint (thick CA).

If you want your kit to come out light and strong and durable, you will need to buy more than one bottle of glue.

Good luck and good shopping!

Epoxy is required for firewalls, joining wings, attaching wing hold down components, attaching the empenage, landing gear blocks, etc. - any place under high stress. I learned to build before CA came out and prefer to use alaphatic resin, otherwise known as carpenters glue (Titebond II, Elmer's Carpenter glue). I do use CA on some occasions, but don't care for the fumes when it flashes off so I use it sparingly. For the rest you can use a variety of different adhesives, and it all comes down to what you like to work with.

Most of the construction is up to you. I use alot of Elmers brand carpenters wood glue. But it takes time to build because of glue drying time. I have built, in the past, with moslty CA. It came out OK and was faster but I like the slower wood glue.
One area where you really have no choice (you do but it is better to heed this advice) is extra strength areas like Firewall, landing gear blocks and joining wing halfs. Buy some 30 minute epoxy for these areas.

CA fumes can be harmful to your lungs and other respiratory parts. Some people are also allergic to it. Then there are the times when you will glue yourself (or the plane/part) to something unintentionally (including yourself).

All the above information is very good. I like to use tite bond 2 as it has a good working time, makes good joints and helps me to not build to fast. Gives me time to make a plan before i move forward. One of the only glues I would not recommend is Gorilla Glue. It expands to much, is hard to work with and generally a blathering mess..strong as hades but definatly their are better choices. CA glues are good when you need it to stick right now and not move just watch the fumes, use well ventelated area. Good luck with your kit.

May your joints be tight and your blades forever sharp

There is a great use for Gorilla (polyurethane) Glue - and that is to sheet foam wing cores. Since it expands to fill gaps it works great bonding balsa and plywood to the cores, and you no longer have to pre-glue the sheets together to make one large sheet - just tape them together and the glue fills in the gaps (but you do want to have a good fit between sheets as a general practice). It's a lot easier than using double sided wing tape, sorghum or contact cement.

Hi!
I only use Ca glue (Flash, medium and thin) and accelerator , ocationaly 12min epoxy for joining foam wings. Very seldom aliphatic glue.

Ask 10 RCers the same question, you will get 12 answers. As bigedmustafa said there is no best for each case. In today's world there are many options. Like most, I use a lot of the carpenter's glues. I also use a lot of CA, both thin and thick. I also use a considerable amount of epoxy, both 5' and 30'. The different uses are fairly well illustrated in the above posts.

With CA, I suggest a fan operating to blow the fumes away.

Another tip is if you want to move right along when doing the carpenter's glue thing, some dabs of CA can stick it together and you can continue working while the carp. glue is drying without much pinning/clamping. My attention span in my old age is fairly short so I have to make good use of any building time. The glue is always dry by time I get to the flying field.
Heavy-High stress and/or vibration areas -- epoxy.
Laminated or larger wood joints -- carp. glue with a dab or two or a few, CA
Those items not subjected to much vibration/stress, CA

Try that to start and you will be safe. Then You will develop your own system/s and wonder why you ever asked us anything at all.
