CONCEPT The original idea here was to create another ship from the ‘Cinderella’ world, this time a smallish courier or orbital fighter. After building it, I got to wondering if I could believably portray a very large ship with a very small rocket model.

PARTS LIST

BT-20 6" long (153mm)

NC-20 Estes ‘cockpit’ style from the assortment pack

BT-80 1" wide (26mm), sliced in half to give you a semi-circle

mini-engine spacing tool a little yellow tube Estes provides to insert a mini-engine block into a BT-5. Or use a 1.75" (45mm) length of BT-5.

mini-engine mount *without* the engine hook

shock cord

streamer

1/8" launch lug about .75" (18mm) long

1/16" (2mm) balsa stock

Rainbow tape aka Prism tape, look in craft or auto parts stores. 

1. Mark the BT-20 body tube for 4 fins, spaced 90 degrees apart.

2. Assemble the motor mount, glue it into the body tube.

3. Cut out the 2 fins according to the diagram and round the leading and trailing edges. Leave the root and tip edges square.

4. Glue the 2 fins to opposite sides of the body tube, even with the back end.

5. Glue the spacing tool to the bottom of the body tube along the marked fin line.

6. Glue the launch lug inside the spacing tool, making sure it’s straight.

7. Glue the BT-80 arch to the fin tips.

8. Make an Estes style shock cord mount and glue it into the front of the body tube.

9. Attach the nosecone.
 

Alternately, you can finish the Starbow as a small courier (or fighter), as originally intended. Mask and paint the cockpit, add some lettering and striping, and you’re good to go. (Hmmmm, the Corporation discovered that a 1/400 downscale, fitted with different engine technologies, was a capable craft in it’s own right...)

LAUNCH REPORTS

Make sure you friction fit the motor well, although I suspect that if it spits the casing instead of the streamer, it’ll be light enough to tumble recover without major damage.

First flight of the Starbow was made using a 1/2A3-2T. Very quick acceleration, but the delay was too short. Recovered without real damage, although a minor paint chip occured at the top edge of the body tube, probably from the nosecone ejection at speed. 

Second flight was made using a 1/2A3-4T. Another quick boost, and this time the delay was acceptable. Recovered without problems.

Third flight was attempted with an A10-3T. At ignition, the engine CATO’d, firing the entire propellant upwards through the body, knocking the nose cone off, then continuing upwards in a flaming mass. The casing was fired backwards, dinging the rear edge against the lip of the blast deflector, and landing in the grass about 5 feet from the pad. Inspection showed absolutely no damage done to the Starbow. Very lucky!

Fourth flight was successful on an A10-3T. Perfect flight, perfect recovery.

Unfortunately, although the Starbow survived a CATO’d A10, she didn’t fare as well against a 10 year olds’ knee. She was accidentally crushed. The remains have been towed into spacedock where a complete rebuild is under way. Photos will be coming as soon as the Starbow is ready to fly again.
