spars. Epoxy is needed
for hardwood motor
mounts that are subject
to vibration, and other
high-strength areas such
as dihedral braces and
landing gear supports.
Most FF models never
need epoxy, so a few
viscosities of CA glue
will do nicely. CL and
smaller RC models
need CA, as well as
epoxy on critical areas.
Larger models, such as
my 50cc Mr. Mulligan,
need many types of
adhesives—lots of thin,
There are many brands, but I chose to use the Mercury Adhesives
line sold by Atlanta Hobby. The company has a full range of glues
made in the US that carry a great unconditional warranty.
The next stop down the road is to pick up the necessary
hardware. Perhaps in your past experiences of putting kits or
ARFs together, you’ve run across hardware that didn’t meet your
expectations. In a plans build, you’re free to choose anything you
If you like hex-head screws, buy those. If you don’t like CA-type
hinges, choose some proper hinge points or plastic hinges. Find the
motor mount, fuel tank, wheels, pushrods, etc. that fit your comfort
level and are the proper size and strength for your model.
For the Mr. Mulligan, Du-Bro supplied a great deal of the
hardware, hinges, tubing, etc. I choose to use a fuel tank from J&L
Power Products called the RotoFlow. It’s a great premade tank
system (clunk installed).
Another consideration is fiberglass parts such as the cowl and/
or wheel pants. More ambitious modelers than I
simply create molds and make their own parts.
I purchased a completed cowl and wheel pants
from Fibertech N More. These were created
specifically for this Mr. Mulligan so it was a great
The last stop on our trip is tool selection. If you
have constructed a few built-up wood models
from a kit, you should have nearly everything you need. At a
minimum, you’ll need a hobby knife with extra blades, a small
handsaw, clamps of various sizes, sandpaper, a drill and bits, and a
rotary tool with a few cutting/grinding/sanding accessory bits.
I don’t use many power tools for my builds, but I have found
that a small jigsaw, a drill press, and a 12-inch rotary disc sander are
invaluable additions to my shop. I bought these at my local Harbor
Freight store. My rotary tool (currently a Dremel 4200) is probably
the most-used tool in my shop!
Some modelers also utilize jigs when building. They guarantee
a straight, true airframe when correctly used. I’ve never used one,
but there have been times when a jig would have been easier than
