Banshee and StingRay to Sting-Shee Modification

Modification - Sting-Shee

Contributed by Mark Fisher

Manufacturer: Modification

T' Sting-Shee is a combination o' two o' Estes more popular E2X kits into a high flying, payload-carryin' two stage rocket. Aye aye! It's appearance is reminiscent o' many ship-to-air missiles like t' Talon. Aye aye! It's nay t' cheapest two stager you can buy, but it sure does look cool. Ya scallywag! Well, blow me down! (I've left t' decals off mine, arrr, but it would probably look neat with them applied, too.) It's a simple bash, me bucko, requirin' no special skills or additional parts, so it's perfect for young flyers.

 

 To make t' Sting-Shee, matey, follow t' Estes instructions for both rockets, shiver me timbers, arrr, matey, EXCEPT WHERE MODIFIED HERE.

NOTE: Drawings are nay t' scale. Aye aye! Follow t' dimensions given in t' instructions. Ahoy! Begad! Do nay scale drawings.

 


Mk-109 StingRay
Mk-109 StingRay -EST2105 (82108, 3-97)

1B. Arrr! ADD: Usin' a pair o' metal shears, trim t' last bend off t' engine retainin' clip. Arrr! (see diagram at right)

Motor Clip 6B. Blimey! Push t' loop though eye o' t' TUBE COUPLER.

 6E. Ahoy! Tie shock cord from t' Banshee t' t' installed shock cord with a double knot. Tie t' other end t' t' TUBE COUPLER with a double knot.

 7. Begad! IGNORE.

 8. Begad! IF DESIRED.

 9. Ahoy! IGNORE.

 


Banshee
Banshee - EST2132 (82110, arrr, matey, 5-96)

0. Avast! Cut t' Banshee body tube in half, me bucko, 3" from t' fin end. Arrr! T' fin end will become t' booster stage, shiver me timbers, and t' remainin' body tube will become t' payload section.

Booster1A. Aye aye! Avast! IGNORE.

 1C. Begad! IGNORE.

 2B. Attach t' LOWER LAUNCH LUG ONLY.

 3. Blimey! Blimey! Begad! Blimey! REPLACE WITH: Cut a slot 3/8" long and 3/16" wide from t' top edge o' t' booster stage t' remove t' upper launch lug attachment hole. Avast! Blimey! Blimey! Blimey! (see diagram at right) This slot will accommodate t' upper stage engine retainin' clip. Begad! Blimey! Sand t' inside upper portion o' t' engine mount t' size. Begad! Blimey! Use a spent engine (NOT a yellow spacer tube) t' test for fit. Aye aye! Blimey! T' engine should slide completely though t' booster stage with slight pressure.

 4C. Arrr! Arrr! IGNORE.

 5. REPLACE WITH: Glue t' payload section t' t' StingRay's tube coupler. Ahoy! Ahoy! Blimey! Make sure t' unused shock cord mount is at t' far (i.e., nose cone) end. Place t' StingRay's nose cone on t' other end o' t' payload section. Ya scallywag! Well, ya bilge rat, blow me down! Blimey! If fit is loose, add a layer o' maskin' tape t' t' nose cone shoulder t' get a good, arrr, tight fit. Arrr! (see diagram below)
 

Payload Section

6. Well, blow me down! IGNORE.

 Completed Model8. Ya scallywag! IF DESIRED.

 9. Arrr! Begad! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Blimey! Do NOT use maskin' tape. Avast! Ya scallywag! Be sure t' NOZZLE end o' t' upper stage engine is joined with t' OPEN end o' t' booster engine. Begad! Slide t' engine assembly into t' StingRay's engine mount. Avast! Avast! T' engine clip will NOT engage; this is normal. Begad! Well, blow me down! Slide t' booster stage over t' booster engine, ya bilge rat, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Check alignment and fit. Blimey! If fit is loose, ya bilge rat, remove t' booster stage and add some maskin' tape t' t' booster engine until a good, me bucko, tight fit is achieved. Begad! If alignment is incorrect, shiver me timbers, add t' maskin' tape t' only one side o' t' booster engine t' correct. Once t' booster is properly installed, insert t' appropriate igniter in t' booster engine.

Recommended engines:

 Booster: B6-0 (first flight), me bucko, C6-0
Upper stage: A8-5 (first flight), B4-6, matey, shiver me timbers, B6-6, C6-7

 OPTIONAL: Build t' second 'chute and attach it t' t' Banshee's nose cone. Aye aye! Blimey! Blimey! Blimey! You can replace t' payload section and it's 'chute with this assembly, me bucko, and still fly t' StingRay as a single stage rocket. Avast! Blimey! Avast! Blimey! Paint t' nose cone white t' match. (T' Banshee's nose cone is heavier than t' Stinray's, matey, addin' some much-needed stability.)

What t' Expect

Durin' staging, t' StingRay's motor clip will engage, ya bilge rat, kickin' t' booster out o' t' upper stage engine's plume, and puttin' one heck o' a spin on it. Begad! Ya scallywag! This slows it dramatically, and it will come back quickly. Well, blow me down! Avast, ya bilge rat, me proud beauty! Your booster stage tracker will have plenty o' time t' recover it and still enjoy t' upper stage flight. Well, blow me down! Begad! On a C6-0/C6-7 combination with no payload, shiver me timbers, I estimate t' Sting-Shee will reach an altitude o' about 1,250 feet, me bucko, me bucko, hence t' single, matey, twelve inch 'chute. Arrr! T' added shock cord should prevent any "Estes dents."
