In addition to common household tools and hobby tools, this is
the “short list” of the most important items required to build the
YAK 55.

Great Planes Pro

Foam Safe CA is recommended.

Low-temperature, hot-melt glue gun and glue

(WOOU1445/WOOU1446)

Hobby knife with #11 blade (HCAR0105)

Thin, Foam Safe-CA (GPMR6069)

Threadlocker cement (GPMR6060)

Here is a list of optional tools mentioned in the manual that
will help you build the Great Planes Yak 55.

Great Planes CG Machine

(GPMR2400)

Household string

Common straight pin

Fuse = Fuselage

Fin = Vertical Fin

LE = Leading Edge

TE = Trailing Edge

LG = Landing Gear

Ply = Plywood

Stab = Horizontal Stabilizer

" = Inches

SHCS = Socket Head Cap Screw

mm = Millimeters

To convert inches to millimeters, multiply inches by 25.4
(25.4mm = 1”)

• When you see the term 

test fit in the instructions, it

means that you should first position the part on the
assembly without using any glue, then slightly modify or
custom fit the part as necessary for the best fit.

• Whenever the term 

glue is written, you should rely upon your

experience to decide what type of glue to use. When a specific
type of adhesive works best for that step, the instructions will
make a recommendation. Since this model is constructed
from foam, we recommend the use of foam-safe CA glues and
epoxy 

only. Do not use standard CA glue on this model as

it will dissolve the structure.

• Photos and  sketches are placed before the step they

refer to. Frequently you can study photos in following steps
to get another view of the same parts.
