PREPARE TO BUILD
1. If you’ve already purchased the retractable landing gear, or as soon as you do, take the air lines out of the package. Unravel the lines and hang them somewhere in your shop. When it’s time to install the lines they’ll be
nice and straight and they’ll be easier to work with. 2. Remove all the parts from the box. Use a ballpoint pen (not a felt-tip pen) to lightly write the name or size on each piece so it can be identified later. Use the
die-cut patterns
on pages 8 & 9 to identify and
mark the die-cut parts before removing them from their die sheets. Many of the parts already have numbers stamped on them, but in some cases the numbers are located beside the part or only on the die drawings in the manual. If a part is difficult to remove from its die sheet, don’t force it out. Instead, cut around the part with a hobby knife and a #11 blade. After removing the parts from their die sheets, lightly sand the edges to remove slivers or die- cutting irregularities. As you proceed, it’s not necessary to save every scrap of wood, but some of the larger pieces of wood should be saved. 3. Separate the parts into groups such as stab, fin, wing, and fuse. Store smaller parts in zipper-top food storage bags.
BUILD THE TAIL SURFACES
BUILD THE VERTICAL STABILIZER (FIN) ❏ 1. Unroll the fuselage plan, then re-roll it inside out
so it will lay flat. Cut out the fin plan, then position it over your flat building board and cover it with Great Planes Plan Protector or wax paper so glue will not adhere.
Note: If you plan to build your Arrow with any kind of a
scale lighting system, now is the time to drill or cut any
holes in the ribs necessary to accommodate the wiring.
❏ 2. Fit the die-cut 3/32"[2.4mm] balsa fin ribs R1
through R6 into the notches of the die-cut 1/8"[3.2mm]
balsa fin trailing edge and the die-cut 1/8"[3.2mm] balsa rudder sub leading edge. Note that all of the
notches are slightly oversize so the parts can fit at an angle. Also note that a portion of the fin trailing edge and rudder sub LE protrude below the assembly, but will be trimmed off later. Make certain the parts are accurately positioned over the plan and hold them to the building board with T-pins.
❏ 3. Make sure all the jig tabs are fully contacting
the building board, then glue the assembly together.
❏ 4. Use a bar sander with 80-grit sandpaper to sand a bevel on the leading edge of all the ribs. Do one rib at a time starting with rib R6 at the top. Hold
the rib with your fingers and draw the bar sander down past, resting it against the other ribs to get the correct angle. ❏ 5. Center the 3/32"x 1/2"x 15"[2.4 x 12.7 x
380mm] balsa fin sub leading edge vertically on the
front of the ribs, then glue it into position.
❏ 6. Use a razor plane and/or a bar sander to shape
the top (left side) of the sub leading edges and the trailing edge so they are even with the ribs. Note: Make sure none of the T-pins protrude above any of the parts so they won’t catch.
