. You must take sufficient time to build straight, true and strong. PROTECT YOUR MODEL, YOURSELF & OTHERS BY FOLLOWING THIS IMPORTANT SAFETY PRECAUTION 3. You must properly install all R/C and other components so that the model operates properly on the ground and in the air. 4. You must test the operation of the model before the first and each successive flight to insure that all equipment is operating correctly. You must also make certain that the model has remained structurally sound.

REQUIRED ITEMS IMPORTANT BUILDING NOTE: During construction you will be using a number of balsa sticks to frame various assemblies. Ample material is included but you should study the plans, then make an effort to cut the longest pieces you will need first. Label the pieces as you cut them for later reference. By doing this now, you won’t have to splice pieces together later. ❏ 2-3 channel radio with 2-3 micro or mini servos ❏ Top Flite® MonoKote® covering (approx.

❏ ❏ 5. Using aliphatic resin, glue the 1/8" x 3/8" BUILD THE WING x 24" hardwood inboard spar to the inboard lower sheeting, flush with the rear edge. Similarly, glue the 1/8" x 3/8" x 36" balsa outboard spar to the outboard lower sheeting. Be careful not to glue the outer panel to the inner panel. NOTE: It is easier to build the inboard and outboard panels at one time, although it is not important to do so. Just don’t glue them together as they must be separated to prepare them for the polyhedral joint.

1/4" I.D. FIBERGLASS ARROW SHAFT 3/32" BALSA WEDGE TAPER END WITH SANDPAPER TRAILING EDGE STOCK NOTE: The Bird of Time uses a “Phillip’s Entry Airfoil.” This requires the bottom leading edge sheeting to be pulled up onto the ribs when they are glued to the sheeting. To do this easily, take some 3/32" balsa from your scrap box and cut a piece about 6" long and 1/2" wide. Sand one end to a narrow taper over the last inch.

“A” ribs between the top and bottom spar cutouts and glue this to the end of the innermost shear web. Make sure the webs are aligned with the spars in the two bays with plywood shear webs. While the epoxy cures, it’s a good time for a cup of coffee. The rest of the wing goes quickly after all the glue has cured. ❏ ❏ 17. Cut the remaining four “AA” ribs and one ❏❏ 15. Fit the four plywood shear webs to the inboard panel. Sand the inner “AA” rib to fit as needed. Do not glue at this time.

❏ ❏ 7/16" x 1/2" leading edges for a good fit at the polyhedral joint and glue them in place. Hold them firmly in place with masking tape until the glue dries. 24. Trim the last “A” rib to fit at the polyhedral joint. Use 6-minute epoxy to glue the “A” rib and the two plywood gussets in place. ❏ ❏ 25. Trim a piece of 1/16" x 4" x 36" balsa ❏ ❏ 33. Sand the root of the inboard panel flat and glue the plywood root rib in place. sheet to 24". Save the cutoff piece for use later.

iron to reseal the glue. Set the iron to it’s highest setting and then press the sheeting back into the rib with the iron. When you remove the iron, continue to press the sheeting to the rib with a cloth. The sheeting should now be firmly adhered to the rib. 2" SPAR 1/8" ❏❏ 7. Trim the main spar to length from 3/16" hardwood. Taper the last 2" at the outboard end, to 1/8" as shown.. NOTE: In the following steps you will be cutting and gluing ribs for the stab from 1/16" x 1/4" balsa sticks.

smaller tube in the front hole and the larger tube in the rear hole. Again, be sure the tube is exactly along the centerline of the spar. STAB ❏ 17. Taper the inboard root pieces as shown on the plan with sandpaper. Cut the center stab sheeting from leftover 1/16" wing sheeting and glue it in place. It will rest on the forward triangular brace and stick up about 1/32", but this will be sanded to fair with the leading edge. 1/16" HOLES ❏ 18.

❏ 7. Remove the pins from the fin. With the fin flat on the building board, sand it flat. Fit the 1/16" fin skin on the fin, being careful to align it with the trailing edge and bottom of the fin. Glue the fin side to the fin with thick CA or aliphatic resin. When the glue is dry turn the fin over and glue the 1/8" die-cut dorsal fin to the forward part of the fin skin. Align the dorsal fin with the skin along the bottom edge and at the leading edge.

❏ 4. Glue the 1/8" balsa rear fuselage side to the front side with CA on both the left and right sides. ❏ 9. If you will be installing an optional tow hook release mechanism you will need to cut the rear of the 3/8" forward bottom block to fit. Note the forward and aft blocks join together in the middle of bulkhead F2. After fitting the tow hook release skip to step 11. ❏ 5. Locate the 1/16" balsa die-cut fuselage front and rear doublers and fit them to the sides.

gluing one small section at a time. Hold the fuselage in one hand and bend the bottom block until a section is aligned with the side, then squeeze the sides together. From the inside of the fuselage tack glue this spot to the sides with thin CA. Proceed down the length of the fuselage until it is tacked along the entire length, fore and aft. Now wick thin CA into all the joints where the bulkheads and bottom block meet the sides. As you do so, firmly squeeze the sides together to assure a tight joint.

❏ 5. Install the antenna tube (not included) if you are using one. I believe this quote is from Dave Thornburg: “If I catch you running your antenna out from under the wing and straight back to the tip of the rudder or stab, I will personally jump up and down on your Bird of Time until it is no more. Antennae go inside fuselages, out of the slipstream.” ❏ 10. Cut a 1/4" long piece of the small aluminum tube and clean out any burrs. Install this piece in the holes at the end of the swivel clevis.

spectrum. When you find the setting be sure to mark it on the side of the fin so you can get it back again. Bear in mind that C.G. changes and changes in airdensity will have a small affect. FINISHING ❏ 1. We recommend you use Top Flite® MonoKote® film to cover the wings and tail as it adds a great deal of strength and rigidity to these parts. The fuselage will be far more interesting. If you regard applying MonoKote film to compound curves as an interesting challenge, you will have a ball.
