The Egg Tosser was designed for NAR competitors. It has a low drag design, and features elliptical shaped balsa fins. It works well in both the altitude and duration event categories. It also includes a lightweight see-through nose cone that allows you view whether or not your egg was broken during the flight. This rocket comes with pre-molded sponge foam protectors to give your egg a better chance of survival. They are soft and conform to the egg, preventing it from shifting around inside the egg capsule. The foam protectors are also washable with soap and water if they happen to get covered in egg yolk.

This rocket can be launched from a standard ⅛” diameter rod. Alternatively, you can use the included Fly-Away Rail Guide which lowers the drag of the rocket by removing the launch lugs and their stand-offs. The rail guides fall off immediately after lift-off, so the rocket can fly higher and faster. They do however require that you launch the rocket from a standard high-power launch rail. The additional advantage is that the rocket is sup-ported for a longer distance, allowing it to build up speed and maintain a straighter trajectory. Because it will fly so high, the rocket comes with a colorful orange parachute to let you track the descent. You’ll love this competition style rocket because it is easy to build and has such fantastic performance.

Assembly Steps � Step 1: Cut a small notch on the inside of one

green 18-24 centering ring. This notch will be for the shock cord to fit under the ring and over the engine mount tube.

Motor Retention Options (You have to make your first choice):

This rocket kit comes with a metal engine hook. This works fine for modelers with limited expe-rience that want a way to quickly remove the engine after flight. But if the rocket is intended for competition, you may want to leave off the engine hook to save a little extra weight. You can still tape the motor into the rocket for flight.

If you decide to add the engine hook, ignore steps

2 through 5

Engine Mount Assembly (lighter weight ver-sion, no engine hook):

� Step 2: Pass one end of the shock cord through the green centering ring with the notch cut inside of it and tie the cord around the motor mount tube. Cinch the cord tight to the tube. Run a bead of wood glue around the forward end of the motor mount tube. Slip the ring onto the forward end of the motor mount tube so the front edge of the ring is even with the end of the tube, and the shock cord is running in the pre-cut slot.

� Step 3: With a pencil, mark the other end of en-gine mount tube 1/2 inch (13mm) from the end.

� Step 4: Slide the remaining green centering ring over the back end of the engine mount tube, and glue it just forward of the pencil line. Apply glue fil-lets to both sides of the centering rings and allow to dry.

� Step 5: Mark a rocket engine with a line 1/4 inch (6mm) from one end. This will be used to push the engine block into the engine mount tube. Using a wood dowel, spread wood glue just inside the engine mount tube on the end nearest the shock cord anchor. Slide the blue engine block ring into the tube using the rocket engine to push it in until the 1/4 inch line is just exposed. Remove the rocket engine casing, and wipe away the excess

glue on both sides of the engine block. Allow the glue time to dry. (Skip to Step 10)Page 2

Engine Mount Assembly: With the Engine Hook � Step 6: With a pencil, mark the engine mount tube

2-1/4 inch (5.71mm) from one end. Using a hobby knife, make a small slit at the mark for the engine hook. Insert the end of the engine hook into the slit as shown.

� Step 7: Mark the engine mount tube at 1/2 inch from the end as shown. Glue the green centering ring without the notch over the tube and engine hook at the line just made.

� Step 8: Take the blue ring, and glue it inside the front end of the tube. It should butt up against the part of the engine hook that protrudes inside the tube. Wipe away any excess glue.

� Step 9: Pass one end of the shock cord through the green centering ring with the notch cut inside of it, and tie the cord around the motor mount tube. Cinch the cord tight to the tube. Run a bead of wood glue around the forward end of the motor mount tube. Slip the ring onto the forward end of the motor mount tube so the front edge of the ring is even with the end of the tube, and the shock cord is running in the pre-cut slot. Apply glue fillets to both sides of the centering rings and allow to dry .

� Step 10: Temporarily pass the shock cord through the motor mount and out the rear. This will keep it glue free when gluing the engine mount into the tube. Using a scrap stick of balsa, apply glue 2-1/2 inches (63.5 mm) inside the aft end of the body tube. Also put glue on the aft ring of the en-gine mount. Quickly and smoothly insert the motor mount tube into the aft end of the body tube. The edge of the green centering ring should be even with the rear of the body tube. When the glue is dry, pass the shock cord back through the motor mount, so that it comes out the front end of the rocket.

� Step 11: Fine sand the balsa fin sheets using 200 grit sandpaper before removing the fins. Careful-ly remove all the pieces from the balsa sheet by freeing the edges with a sharp hobby knife.

� Step 12: (Optional) - With sandpaper, you can round-over or airfoil the leading and trailing edges of the fins to reduce drag to achieve higher flights.

� Step 13: Sealing and sanding the balsa fins re-duces drag by making the surface very smooth. It also improves the rocket’s appearance. Apply a coat of sanding sealer to the fins and the launch lug stand-offs with a paint brush. When the sealer is dry, lightly sand the sealed surfaces. Repeat the sealing and sanding procedure until the balsa grain is filled and the fins look and feel smooth.

� Step 14: Apply wood glue to the root edges of one the fins, including on the base of the tab. Allow the glue to dry slightly for a few minutes, then attach it to the aft end of the body tube, as shown in the illustration. Repeat this step two more times as you attach the other fins. Allow the glue to dry.

� Step 15: Apply a bead of wood glue to both sides of each fin-body tube joint. Pull your finger along the joint to smooth out and remove the excess glue. Lay the tubes horizontally while the glue dries. Now you need to decide whether to use the launch lugs or the fly-away rail guides. The launch lugs will allow you to use a conventional launch rod but will add more drag. The fly-away rail guides require the use of a high power launch rail, but lower the drag on the rocket because they will fall off as the rocket leaves the pad (If using the fly-away rail guides, skip to Step 18).

Attaching the Launch Lugs � Step 16: Glue the two launch lugs to the top of the

balsa wood launch lug stand-offs. Allow the glue to dry.

� Step 17: Glue the two stand-offs onto the body tube. The tube is pre-marked with rectangles to indicate where they should be glued. Make sure that the two lugs are aligned, so that the model will slide freely on the launch rod. After the glue has dried, apply fillets of wood glue along the launch lugs and the stand-offs where they touch the tube.

� Step 18: Using a hobby knife, drill a small hole in the base of the clear egg capsule shoulder piece. The hole needs to be just bigger than the diame-

ter of the shock cord.Page 4

� Step 19: Thread the shock cord through the hole made. Tie a large knot in the end of the cord on the egg side of the nose cone. Glue the knot to the inside of the base of the shoulder using thick CyA adhesive (super glue).

� Step 20: Tie a loop in the shock cord near the base of the nose cone. This will be the loop for attaching the parachute.

Parachute Assembly � Step 21: Place the ring tabs in the corners of the

pre-cut parachute, as shown in the illustration. Next, poke holes in the center of the rings with a sharpened pencil.

� Step 22: Find the shroud line and cut the string into three equal lengths. Tie them through the ring holes as shown. Put a little bit of glue on the knots to secure them in place. Allow the glue to dry.

� Step 23: Holding the parachute at the center of its top, pull the lines together to even up the ends. Thread the three looped lines through the loop of the shock cord near the base of the egg capsule.

� Step 24: Take the apex of the parachute and pull it through all three string loops at the same time and then pull to tighten the knot. This securely attach-es the parachute to the rocket.

Fly-Away Rail Guide AssemblyRemove the parts from the laser-cut plywood sheet. Note that there are two of parts “A” and “B” and one of part “C” per side. You’ll perform each step twice to make the two halves.

� Step 25: Glue Part “C” into the square hole of part “A.” Glue the other part “A” on the other end of part “C”. Make sure the "A" and "C" parts are at 90° angles from each other.

� Step 26: Glue one part "B" into the notches on the curved portion as shown.

� Step 27: Glue the other part “B” into the notches on the stand-off portion as shown.

Painting And DecoratingAfter all the glue has completely dried, you can now paint your Egg Tosser rocket. A bright color will help you find it after launch.

� Step 29: Roll a piece of paper and insert it into the aft end of the body tube so you can hold the model while painting it. For competition flights, we suggest a bright fluorescent orange. Follow the directions on the paint can, and always paint outdoors with the wind against your back. Let the paint harden at least 24 hours before proceeding.

� Step 30: When the paint is dry, the decal stickers can be applied to the rocket as desired.

� Step 31: It is recommended that you paint the rail guides a fluorescent color like orange or hot pink so you can find them easily on the ground after the flight.

Displaying Your Completed Egg Tosser Rocket� Step 32: Start the assembly of the simulated

cardboard egg by removing the parts from the laser-cut sheet. Using wood glue, attach the side pieces by sliding them into the notches of the hexagon pieces as shown.

� Step 33: Continue gluing the side pieces into the hexagon until all six are assembled. Allow the glue time to dry.

� Step 34: Remove the display stand parts from the laser-cut sheet. Glue them together using wood glue as shown. Allow the glue time to dry.

To display your rocket, you can insert the simulat-ed egg into the nose cone to align the halves. Put a piece of tape over the joint to keep them together. You

can place the rocket on the stand to display the rocket. Page 6

Launch Supplies NeededTo launch your rocket you will need the following supplies:• A model rocket launching system• Flame resistant recovery wadding• Recommended Rocket Engines: See the motor matrix below.

Rocket Preflight� A. Crumple and insert 4 sheets of recovery wad-

ding into the body tube.

� B. Fold the parachute as shown and insert it into the tube with the shock cord. Then insert the shoulder portion of the egg capsule into the body tube.

� C. Insert one Foam Egg Protector into each of the plastic egg capsules.

� D. Place the egg into the capsule, then add the top capsule piece. The egg centers up the cap-sule pieces. Wrap a piece of 1/2-inch wide clear packaging tape around the perimeter to keep the pieces together.

� E. Insert the rocket motor into the aft end of the rocket by bending the clip back and sliding it in. If you didn’t install the clip, wrap masking tape around the motor and the engine mount tube.

� F. If you’re using the fly-away rail guides, position them on the rocket just in front of the fins. Slide the two rubber bands into the slots on the guides as shown. Test to make sure the parts will easily detach from the rocket.

� G. Orient the rail guides between two of the fins. Insert the fingers of the stand-off into the launch rail and slide the rocket all the way to the base of the rail.

� H. Insert and secure the engine igniter as directed on the engine packaging.

Fly your rocket on a large field that isn’t near any power lines, trees, or low flying aircraft. The larger the field, the greater your chances of recovering your rocket. The launch area around the pad must be free of dry weeds and brown grass. Launch only during calm weather with very little or no wind and good visibility.

� 10. Remove the safety key from the launch controller. � 9. Slide the launch lugs over the launch rod (or into the rail if you’re using the fly-away rail guides) to place the rocket on

the pad. The rocket should slide freely along the rod or rail. � 8. Attach the micro-clips to the igniter. The clips must not touch each other or the metal blast deflector. � 7. Stand back from your rocket as far as the launch wire allows (at least 5 meters - 15 feet). � 6. Insert the safety key to arm the launch system. The light (or buzzer) on the controller should come on.

� Give a loud countdown 5 ... 4 ... 3 ... 2 ... 1 ... LAUNCH!

� Push and hold the the button until the engine ignites. Then remove the safety key and place the safety cap on the launch rod.

Misfire Procedure

Occasionally the igniter will burn, but the motor will fail to ignite. If this happens, the cause is that the pyrogen on the igniter was not in contact with the engines propellant. When an ignition failure occurs, remove the safety key from the launch control-ler and wait 60 seconds before approaching the rocket. Remove the old igniter from the engine and install a new one. Make sure that the igniter is insert fully into the engine and touches the propellant. Secure the igniter as directed on the engine package and repeat the countdown and launch procedure.

Always follow the NAR* Model Rocket Safety Code when launching model rockets.
