This was one of those Ebay purchases I made a low bid on, but never expected to win.
For just over $20.00 I got ten of these kits, quite a bargain for the BT-50 tubes, nose cones, parachute kits and engine mounts. No instructions, engines or igniters were included.
There won't be a blog build on this simple 3FNC rocket.
I found some of the kit pieces interesting.
Pitsco Education sells their own rocket kits and PVC launchers and controllers. This kit included a 11 1/2" long BT-50. EDIT: This is not a BT-50, it is slightly larger. Another Pitsco kit has the student roll their own body tube around a form using gummed tape.
Some kit pieces of interest:
The injection molded nose cone has an internal screw eye lug.
To the right of the nose cone is the smallest screw eye I've ever seen in a rocket kit.
Under the nose cone is the thick, cardstock fin material. The fin pattern is a Big Bertha style. The finished rocket looks like a smaller Big Bertha with a rounded tip ogive nose cone.
The kit includes a printed six-sided parachute (only five tape disks were provided) and kite string shroud lines.
The shock cord is an elastic string, too thin to last any more than a few flights.
Flame resistant tissue paper is included, but doesn't seem to be enough to protect a parachute in the BT-50 sized tube. EDIT: This is not a BT-50, it is slightly larger.
