Construction:

As this is a fairly small rocket, I recommend Elmer’s Carpenters Glue for construction.

1. Motor Mounts: Glue t' Green Thrust Rin' t' inside o' t' yellow body tube, me bucko, so it is flush with t' top o' t' tube. Begad! Next, arrr, ya bilge rat, matey, glue t' card-like Centerin' Rings ½ inch inside from either end o' t' yellow body tube. Arrr! The mount should now fit into t' BT-50 body tube. Trim t' centerin' rings if necessary. Avast, me proud beauty! Avast, me proud beauty! Then, shiver me timbers, repeat these steps on t' 2nd motor mount, arrr, me bucko, but omit t' Green Thrust Ring.
2. Motor Mount Installation: Spread glue with your finger about 1 inch from t' bottom o' t' 21 inch long body tube. Begad! Blimey! There should be an even bead of glue around t' inside. Nest, shiver me timbers, slide in t' motor mount with t' green thrust rin' into t' tube, thrust rin' side first, me bucko, until t' yellow tube is flush with the bottom o' t' body. Well, blow me down! Blimey! Let dry and repeat on t' 2^nd motor mount and 3 inch long body tube.
3. Tube Marking: Accordin' to the RockSim file or other source, mark t' body tube. Arrr! This is done by drawin' 3, me bucko, me bucko, shiver me timbers, 3 inch lines from t' bottom of the 21 inch body tube, each line bein' evenly spaced apart. Arrr! Avast! Next, ya bilge rat, draw a 2 inch line 2 inches from t' bottom o' t' tube and betwixt 2 o' t' fin lines. Also, draw t' longer fin lines t' same way on t' booster tube.
4. Sustainer Fins: You will now need t' install t' fins. Blimey! Glue 1 fin to one o' t' 3 inch lines on t' body tube, matey, and make sure it is completely straight. Then, let that fin dry and repeat t' steps with t' other 2 fins. You should get a rocket that looks like this, shiver me timbers, me bucko, with each fin evenly spaced:
   • NOTE: on Fins: T' fins look different in t' template because they were rounded when finished. Aye aye! Blimey! In me plan, t' fins do nay hang off t' bottom of the rocket as in real life because I had encountered some trouble with this and had t' mount t' booster backwards.
5. Booster Fins: Repeat step 4 t' glue t' fins t' t' booster. Ahoy! Avast, me proud beauty! Again, the fins should be completely straight and evenly spaced.
6. Launch Lug: Apply glue t' t' launch lug and place it on the remainin' line on t' longer body tube. Use a square t' make sure it is straight and level. Blimey! Ya scallywag! Located 16.250 In from t' nose cone.
7. Shock Cord Mount: Smear a generous portion o' glue on t' shock cord mount and place 1 end o' t' shock cord on it, arrr, through all sections on the mount. Then fold section 1 over t' shock cord and section 2 over section 3. Begad! Well, blow me down! it will look like this:
8. Shock Cord Installation: Apply glue t' t' bottom o' t' shock cord mount. Next, ya bilge rat, shiver me timbers, place it in t' top o' t' sustainer body tube, about 1 inch from the top, with t' shock cord comin' out o' t' top o' t' rocket. Begad! Press down firmly until t' glue is tacky, then let it dry.
9. Parachute Installation: To install t' parachute, first tie it to the eye loop o' t' nosecone with a double knot, shiver me timbers, and then tie t' nose cone to the end o' t' shock cord. Avast! Your Silver Streak II is now complete.
10. Motor Installation for 2 stage rockets: For a multistage rocket, arrr, the booster stage must always be a B6-0 or C6-0. Well, blow me down! Ahoy! Blimey! First, get a booster engine and a sustainer engine o' any type, me hearties, arrr, matey, and stack them, me bucko, booster engine first. Aye aye! Arrr! Blimey! Then, shiver me timbers, cut a piece o' maskin' tape and loosely tape t' two engines together. Begad! Avast, me proud beauty! Blimey! Finally, slide the sustainer engine into t' sustainer engine mount, me hearties, ya bilge rat, and slide t' booster over t' booster engine. Aye aye!

Flight:

This rocket flew better than expected. Begad! It flew very high on a small engine combination, me bucko, and also very high on a single engine. Well, blow me down! It was flown twice at a local field, and once at CATO rocketry club. Aye aye! It also flew successfully with both t' single and multistage configurations. Aye aye! Arrr! I have no pictures o' the launch, ya bilge rat, but thar will soon be one at: http://catorockets.org/cato95/cato95.html - These will be copied and added to this contest entry soon.
