All of the other kit parts can be identified by the "Complete Kit Parts List". Sort the different sizes of sticks and sheets into
individual piles to avoid confusion during building. Cut all long pieces of balsa first, followed by medium lengths, before cutting
up any full length strips into short pieces.
YOU CAN'T GET ALONG WITHOUT A GOOD SANDING BLOCK
An assortment of different size sanding blocks are indispensable tools for model
construction. A good general purpose block can be made by wrapping a 9"x11"
sheet of sandpaper around a piece of hardwood or plywood. Use three screws
along one edge to hold the overlapped ends of the sandpaper. Put 80-grit paper on
the block during general construction. Switch to 220-grit paper for final finish
sanding just before covering.
Another handy block can be made by gluing sandpaper onto a 24" or 36" long
piece of aluminum channel stock. Most hardware stores carry a rack of aluminum
in various sizes and shapes. This long block is very useful for sanding leading and
trailing edges accurately.
About The Building Sequence
The quickest and most efficient way to complete a model is to work on several pieces at the same time. While the glue is drying
on one section, you can start on or proceed with another part. Work can even go forward on several sections of the same
assembly at the same time, such as the front and rear sections of the fuselage. Keep in mind that the numbering sequence
used in these instructions was chosen as the best way to explain the building of each major component and is not intended to
be followed exact one-two-three fashion. Start on the wing at No.1 and after doing as many steps as is convenient, flip over to
"Fuselage Construction" and do a step or two or three, then over to "Tail Surface Construction" and so forth. You will, of course,
arrive at points where you can go no farther until another component is available. For example, you need a nearly completed
wing before the fuselage can be entirely completed. Plan ahead! Read the instructions completely and study the full size plans
before beginning construction.
Radio Requirements
You will need at least a four-channel radio system for your Spacewalker to operate the ailerons, elevator, rudder and throttle.
Heavy-duty servos intended for use on 1/4-scale models are required for all of the flight controls. Also, use a receiver battery
with at least a 1000mA capacity to power those servos for a safe amount of time. Be certain that your radio system's frequency
is approved for use in R/C model aircraft. Using a frequency assigned to R/C model cars not only endangers your model to
interference from model car drivers (who may not be in sight), it also is against the law.
About Printed Wood Parts
To answer the question we are sometimes asked - no, we do not print parts on wood to save money. It is actually more
expensive to print the parts using a silk screen press than it is to run an equivalent sheet through our automatic feed die cutting
machine. If we hand-sawed the parts it would be even more expensive and the labor cost would have to be added to the kit
price. We believe that most modelers would rather cut their own out and save the cost. Since there are not many thick parts in
our average kit, it really doesn't consume a lot of the total building time for the builder to do the parts.
WING CONSTRUCTION
The Spacewalker has a wing designed with removable outer panels so that it can be "broken down" into three easily-managed
pieces for transporting. The outer panels are joined to the center section using extruded aluminum wing joiners and are held in
place by three set screws on each side. The following instructions are strictly for the three-piece wing as shown on the plans.
Some modelers may prefer to build the wing as a one-piece unit. This will save about a pound in weight (through the omission
of all the wingjoining hardware), but will require a full-size van or model trailer to transport the model. If you wish to build a one-
piece wing instead of the standard three-piece wing, please read and follow the instructions concerning "How to Build a One-
Piece Wing", included at the end of the Wing Construction Section. You should also read "About the Ailerons", included further
on, before beginning work on the wing.
Notice that a nearly completed wing assembly is needed to complete construction on the fuselage. It is recommended that you
begin to build the wing first so that it will be ready when you reach that point in the fuselage instructions.
