motor tube, 3 rings, hook
plastic parachute 18"
Shield fins 4
vinyl decals peel and stick
mystery part - 3 mystery pcs of balsa
Motors B6-4 first flight C6-5 flies up to 550 feet
23" Length 1.33" Dia.
Read all steps before beginning. Always dry fit the parts on every step that requires glue. And always add a reinforcing bead of glue to all joints the required glue and wipe off excess glue with your finger.
Locate the motor mount parts. Make a small cut big enough for the motor hook 1/8" on the motor tube at 1/4" from the end. Make a mark from the other end of the tube at 1" then turn the tube 180 degrees and make another mark at 1". Put the hook in the cut and slide both rings onto the tube. Making sure the gap in the ring goes over the hook, keep both rings at the ends of the tube.
Put a ring of glue around the tube just before the two 1" marks and a dab of glue on the cut, then put the small end of the hook in the cut and slide the rings up to the lines passing them through the ring of glue. make sure they are straight. Put a ring of glue around the inside of the tube on the FWD end and insert the engine block ring until it stops at the hook. Put a strip of masking tape around the center of the tube, or you can glue a strip of cardstock around it a couple of wraps to secure the hook. Set aside, let dry.
Take out the fins and sand them, keep them together and sand all the edges evenly, then round all the edges except for the root edge.
Cut out the fin marking guide and wrap it around the body tube and tape it. Make pencil marks at each line on both sides.
Using a straight edge, door frame and extend all 4 fin lines the entire length of the tube. mark the lug line and hook line. Extend the launch lug line to 10" and make a mark on the lug line at 9 3/4"
make mark at 2 7/8" from the AFT end of the tube on each of the fin lines.
If you prefer to use the vinyl decals, skip this next step.
This kit comes with multiple options. The card stock fin skins should be glued on using white glue. Use your finger to smear glue and cover the paper completely. Position it on the fin and do the same with the other side of the fin and place it on parchment paper or wax paper on a flat surface. Put a heavy book on it until dry. The vinyl decals will be placed on fins after you have painted them
3: Installing motor mount.
Put a ring of glue around the inside of the body tube at 1 1/2" in the AFT end.
Slide the motor mount in and don't stop until the motor tube is flush with the body tube. Let dry then add a line of glue around the AFT ring at the joint where it meets the body tube. Let dry.
Example pictures from a different build.
Put glue on the root edge of one of the shield fins, stop at the area of the fin where the root edge starts to turn away from the tube.
Place the fin on one of the fin lines with the FWD end/tip of the fin at the 2 7/8" mark.
keep the fin straight and on the line, check alignment until glue dries firmly. Let dry.
TIP: With an ink pen or marker on the very end of the body tube extending your fin line so you can see the position while the fin is being mounted.
Repeat the same process with the other 3 fins.
Glue on each canard fin the same way. Each canard tip should be flush with the FWD end of the tube.
Picture showing position of canards.
Cut out the shock cord mount and smear glue on it with your finger covering it.
lay one end across it and fold one section at a time, add a dot or 2 of glue each time you fold. Then form it into the shape of the body tube. after the shape has set a little, place a few drops of glue inside the FWD end of the body tube at 1 1/2" in and put the cord mount there and hold it until it sets firmly.
TIP: You can use a rubber band and strap the cord mount around the base of the nose cone to form it, do not let it dry fully.
Wash the nose cone with hot soapy water. See parachute instructions. once the parachute is assembled, tie all lines to the eye on the base of the nose cone, and tie the loose end of the shock cord to the same eye as the cone.
