Required materials for assembly
Assembly Instructions
Attach motor clip through the small slit in the motor tube. Apply wood glue around inside edge of motor tube as shown. Insert red thrust ring into motor tube and position until seated against the motor clip.
Apply a bead of glue around the motor tube in the area where the clip goes through the tube. Push a centering ring over the motor tube and the clip as shown. Then apply another bead of glue around the rear end of the motor tube and slide on the remaining centering ring until it is about 15-18 mm from the rear end. To complete the motor mount assembly, add a fillet of glue from each side of both centering rings and place aside to dry.
Slide motor mount assembly with motor hook facing out in to the slotted body tube as pictured. Be sure that motor mount tube and body tube are flush and check that the motor hook is oriented between two of the slots of the body tube. The hook should not be directly beneath a slot, or else it will interfere when assembling the fins!
Glue the half-circular discs to the central column as pictured.
Then apply a bead of glue inside both ends of the tube coupler. When inserting
the baffle in to the coupler, do a twisting motion of one rotation at the same
time.
Tie a noose on one end of the Kevlar cord.
Attach the noose to the baffle with a cow hitch as pictured.
At this stage you can choose whether you want to leave the fin edges square, make them rounded, bevel them or even streamline them. Use a sanding block.
Draw a mark approximately in the middle between two slots.
Then draw an approx. 8 cm long line at each end of the tube using a door frame
or an angle piece.
Apply some wood glue along the root edge and tab of each fin and stick them
into the slots as pictured. Make sure each fin is seated firmly and at the
correct angle on to the body tube for proper adhesion.
Repeat with each fin. Let the glue dry.
Glue the spacers for the launch lugs on the drawn lines and flush to the tube
ends as shown. Be absolutely sure that they are aligned to each other. When
these are fixed, stick on the guide tubes.
Tip: You can check the alignment of the guide tubes to each other with the
help of a launch rod and correct them if necessary.
After all glue has dried, apply a small bead of glue to all joints.
Smooth the glue out with a wet fingertip. Wipe off the excess glue into a
paper towel.
Glue the completed baffle into the lower body tube as shown, but leave half of it sticking out.
Sand, prime and either paint the model as suggested on the packaging or
according to personal preference.
But do not glue the upper body tube!
Screw the lower plastic shell of the nose cone (without Styrofoam insert) to
the wooden disc as shown. Make sure that the shoulder of the wooden disc is in
the middle of the lower shell.
Cut out some material in the center of the bottom of the lower Styrofoam shell
to make room for the screw assembly. Assemble nose cone.
Tie a noose at both ends of the elastic shock cord.
Attach the elastic shock cord to the nose cone as pictured.
Glue the nose cone into the shorter body tube.
Tie the Kevlar cord and elastic cord together.
Pass the shroud line loops of the pre-sewn parachute through the eyelet of the elastic cord. Pass parachute through the loop ends and pull lines tightly against the eyelet.
Apply stickers as shown on picture. Smooth out air bubbles from center to edge.
Fold and pack the parachute according to the displayed steps.
Before launching the rocket, the two halves of the nose cone should be secured with the provided adhesive tape so that the payload (e.g. a raw egg) is not lost during flight. Toilet paper or a cloth can be used as a cushion. See illustration.
