The most popular type of glue modelers use for

general construction of R/C models is cyanoacrylate
or CA glues. Modelers build with CA because it
cures fast (immediately in some cases) and the
pieces do not have to be clamped or pinned together
as they do with traditional adhesives. CAs do,
however, have their own set of special procedures
and precautions that you should follow. Always use

CA in a well ventilated area. Open some windows
or place a fan in the room to circulate the air. Do not

lean directly over your work when you use CA and
look away while it cures or "sets off." CA can cure
immediately upon contact with skin so if you

accidentally bond your fingers, do not use vigorous

motion to separate them. Use CA Debonder
(GPMR6039) or acetone (nail polish remover) or
soak your fingers in warm water for a few minutes.
Never point the tip of a CA bottle toward your face
and be especially careful when you unclog a CA tip.
Hobbico CA Applicator Tips (HCAR3780) are highly
recommended and will help keep the bottle from

clogging. Keep paper towels or tissues close by to

immediately absorb excess CA dropped on your
model or work area. Read all the warning labels on

your CA bottle.

There are different viscosities of CAs intended for
different conditions you will encounter when you

build. Thin CA is great for "tack-gluing," for glue
joints that fit well and for parts that are already
joined but need to be permanently bonded. Medium

CA is used for general construction where you apply

glue to one part, then join it to another. Thick CA is
great for glue joints that don't fit perfectly or parts
that require a little time for positioning before the
glue cures. You will encounter many other conditions
that require one or the other types of CA. For the

Piece 0' Cake all you really need is thin and

medium CA.

CA Accelerator is a chemical that you can spray
over uncured CA to make it cure immediately. A mist
spray of accelerator will do the job. Do not inhale
the vapors! Some modelers "preprime" the parts to
be glued with accelerator, join them, then add the
CA. This way the CA is guaranteed to cure

immediately. This prepriming is especially handy

when you use thin CA because it will cure before all
of the glue soaks into the wood away from the glue

joint. We do not recommend you build your entire
model with this method. Use accelerator only when
necessary. Often, overspray from accelerator used
hours or even days earlier on nearby glue joints will

cause the CA you use on the next step to cure
prematurely and unexpectedly - so be careful!
