I don't think that these kits are still available, but its easy to do. I'm
currently in the process of setting up a basic kit for my groups cubs (young
scouts). Here's how I'm doing it, basically it's built rocket as usual, but
leave out the engine mount and make a few alterations:
1) Build the rocket as per the instructions, but leave out the engine mount.
2) A simple hook can be cut directly out of the body, or you can glue on a hook
made of plastic.
3) Next cut out a rectangular section of the body, about one-half to one-third
as long as the rocket. I found that a section that covered 1/3 of the rockets
diameter worked best (this means that one fin will be on the flap).
4) Reattach the section cut out in step 3 with tape, such that the piece forms
a flap that is "hinged" at the top.
5) Cut a small slot near the cone, right above the flap you just made. Cut a
thick elastic so its straight, and glue one end into the slot.
6) Cut another slot in the center of the flap. Glue the other end of the
elastic into this slot. Make sure the elastic is taunt enough to hold the flap
open at about 45 degrees when no pressure is applied.
7) Attach the parachute or streamer level with the top of the flap, but on the
opposite side of the body.
8) Make a launcher by drilling a hole at the end of a section of PVC pipe or
wood doweling. Run a thick elastic through this hole. To launch pack the
chute into the body, and hook the rocket onto the elastic. Pull back and let
go. The force provided by the air flowing around the rocket should keep the
flap closed until close to apogee. If you get "premature ejection" replace the
elastic with a longer length. This is the biggest problem I had when designing
the rockets for my group, and it took me awhile to fine tune the elastic length
to what worked best. I found the length I described above worked well, but I'd
imagine this will vary greatly depending on what kit you use and on your
If you are planning on using, rather then a child, try replacing the elastic on
the launcher with a piece of surgical***tubing. It'll be much harder to
launch the rocket, but you can easily double or triple the altitude the rocket
reaches. One of the other leaders is currently trying to make a simple
catapult so we can really make the rockets fly. I think the kid's will love
