Actually this is a re-build of one of my older Single motor Night Launch models. the Original burned off the elastic shock-line. leaving only the LED lighted forward section to come back on it's 24" X-Form Nylon chute But at least I got the important parts back.
This time John says to himself....We ain't gonna loose the booster portion of this Rocket again!
So from the Body tube pile a new 18" BT-55 was selected. for the motor mount I used the Heavy wall, Foil lined BT-50 with the last of my pre-made BT-55/BT50 14ply sho-card centering rings. But this time we weren't about to use Kevlar or just elastic as the Shock-cord anchor. Nope this time I went with 1/16"x 15", 500lb test, 1x19strand Stainless aviation cable with crimped eye loops. To this is added another 48" of 1/8" oval braided Elastic.
Since this entire rocket is a NO Paint Project. The Main body tube was covered with Blue Metal flake adhesive backed Vinyl. our TA-50/55 transition was previously CA hardened and covered with Red Metal Flake vinyl. to balance it out a little I covered the extended BT-50 motor tube with Red Vinyl also.
Fins for this model are .063" White styrene plastic covered with Blue & Red Metal Flake Vinyl and 1/4" square Silver Art-Foil to give a sort-of Red, White & Blue overall color scheme.
Attachment of these Styrene fins to the cardboard Body require a bit more then butt joints but didn't want to bother with TTW tabs. Instead used the epoxy rivet method to mount the .57" OD clear cylume holders and to the body tube.
Because this is a fairly light model with a D12 I decide to also help control the altitude a bit by Canting all 3 fins Left 2° to induce a pretty high spin rate. this should also make the Cylume Glo-stick tipped fins make a nifty pattern in the night sky. These fins are further strengthened by Blue Tinted Epoxy Fillets.
Our old forward end Illuminated section is made up of a .97" od x 14.75" clear Polyethylene mailing tube with an internal .44" x 13" frosted sanded clear tube containing 5- multi-color 5mm 3000-5000mcd LEDs powered by a single 3v 20mm CR-2032 Lith coin cell and holder. Our Nose cone is an unpainted Yellow PNC-50y Plastic cone with a 5000mcd red Led which lights the cone RED during flight.
All together the model I call "ONE LONG NIGHT" is 38" long. with a LOWT" with a D12-5 of 237.6g or 8.38oz.
Man I can't wait to get this one back in the air Saturday Sept 20th. Should be fun both during it's daylight Shake down first flight. and hopefully we get it back to fly at the clubs annual Night Launch a little later that evening.
