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, matey, me hearties, so it is flush with t' top o' t' tube. Ahoy! Blimey! Blimey! Blimey! Next, glue t' card-like Centerin' Rings ½ inch inside from either end o' t' yellow body tube. Avast, me proud beauty! Blimey! Well, blow me down! Blimey! The mount should now fit into t' BT-50 body tube. Avast! Blimey! Blimey! Blimey! Trim t' centerin' rings if necessary. Aye aye! Blimey! Then, shiver me timbers, repeat these steps on t' 2nd motor mount, 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. There should be an even bead of glue around t' inside. Nest, slide in t' motor mount with t' green thrust rin' into t' tube, thrust rin' side first, arrr, me bucko, until t' yellow tube is flush with the bottom o' t' body. Begad! Avast, me proud beauty! 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. Well, blow me down! Avast! This is done by drawin' 3, 3 inch lines from t' bottom of the 21 inch body tube, each line bein' evenly spaced apart. Blimey! Next, ya bilge rat, arrr, draw a 2 inch line 2 inches from t' bottom o' t' tube and betwixt 2 o' t' fin lines. Ya scallywag! Avast, me proud beauty! Also, draw t' longer fin lines t' same way on t' booster tube.
4. Sustainer Fins: You will now need t' install t' fins. Glue 1 fin to one o' t' 3 inch lines on t' body tube, me hearties, arrr, shiver me timbers, and make sure it is completely straight. Ahoy! Then, arrr, ya bilge rat, let that fin dry and repeat t' steps with t' other 2 fins. You should get a rocket that looks like this, me bucko, with each fin evenly spaced:
   • NOTE: on Fins: T' fins look different in t' template because they were rounded when finished. 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. Blimey! 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. Ya scallywag! Use a square t' make sure it is straight and level. 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, shiver me timbers, through all sections on the mount. Blimey! Begad! Then fold section 1 over t' shock cord and section 2 over section 3. Ahoy! Aye aye! it will look like this:
8. Shock Cord Installation: Apply glue t' t' bottom o' t' shock cord mount. Next, place it in t' top o' t' sustainer body tube, me bucko, about 1 inch from the top, with t' shock cord comin' out o' t' top o' t' rocket. Blimey! Blimey! Press down firmly until t' glue is tacky, me bucko, arrr, me hearties, 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, and then tie t' nose cone to the end o' t' shock cord. Ahoy! Your Silver Streak II is now complete.
10. Motor Installation for 2 stage rockets: For a multistage rocket, matey, the booster stage must always be a B6-0 or C6-0. Ahoy! First, me hearties, matey, ya bilge rat, get a booster engine and a sustainer engine o' any type, me bucko, arrr, and stack them, booster engine first. Begad! Begad! Then, cut a piece o' maskin' tape and loosely tape t' two engines together. Ya scallywag! Finally, slide the sustainer engine into t' sustainer engine mount, and slide t' booster over t' booster engine. Avast!

Flight:

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