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, ya bilge rat, payload-carryin' two stage rocket. It's appearance is reminiscent o' many ship-to-air missiles like t' Talon. It's nay t' cheapest two stager you can buy, me bucko, ya bilge rat, but it sure does look cool. Blimey! (I've left t' decals off mine, me bucko, but it would probably look neat with them applied, arrr, too.) It's a simple bash, me hearties, arrr, ya bilge rat, requirin' no special skills or additional parts, so it's perfect for young flyers.

 

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

NOTE: Drawings are nay t' scale. Follow t' dimensions given in t' instructions. Do nay scale drawings.

 


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

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

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

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

 7. Begad! IGNORE.

 8. Begad! IF DESIRED.

 9. IGNORE.

 


Banshee
Banshee - EST2132 (82110, ya bilge rat, 5-96)

0. Ya scallywag! Avast, me proud beauty! Cut t' Banshee body tube in half, 3" from t' fin end. T' fin end will become t' booster stage, ya bilge rat, and t' remainin' body tube will become t' payload section.

Booster1A. Arrr! Begad! IGNORE.

 1C. Ya scallywag! Arrr! IGNORE.

 2B. Aye aye! Attach t' LOWER LAUNCH LUG ONLY.

 3. Aye aye! 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. Begad! (see diagram at right) This slot will accommodate t' upper stage engine retainin' clip. Ya scallywag! Blimey! Sand t' inside upper portion o' t' engine mount t' size. Ya scallywag! Use a spent engine (NOT a yellow spacer tube) t' test for fit. T' engine should slide completely though t' booster stage with slight pressure.

 4C. Blimey! IGNORE.

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

6. IGNORE.

 Completed Model8. Begad! IF DESIRED.

 9. Arrr! Avast, me proud beauty! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Blimey! Do NOT use maskin' tape. Arrr! Be sure t' NOZZLE end o' t' upper stage engine is joined with t' OPEN end o' t' booster engine. Avast, me proud beauty! Slide t' engine assembly into t' StingRay's engine mount. Arrr! Begad! T' engine clip will NOT engage; this is normal. Avast! Arrr! Slide t' booster stage over t' booster engine, ya bilge rat, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Blimey! Aye aye! Check alignment and fit. Begad! Ya scallywag! If fit is loose, remove t' booster stage and add some maskin' tape t' t' booster engine until a good, tight fit is achieved. Blimey! If alignment is incorrect, add t' maskin' tape t' only one side o' t' booster engine t' correct. Avast, me proud beauty! 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, shiver me timbers, B6-6, arrr, C6-7

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

What t' Expect

Durin' staging, shiver me timbers, t' StingRay's motor clip will engage, shiver me timbers, me bucko, kickin' t' booster out o' t' upper stage engine's plume, ya bilge rat, shiver me timbers, and puttin' one heck o' a spin on it. Begad! Begad! This slows it dramatically, and it will come back quickly. Ahoy! Your booster stage tracker will have plenty o' time t' recover it and still enjoy t' upper stage flight. Avast! 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, hence t' single, twelve inch 'chute. Blimey! T' added shock cord should prevent any "Estes dents."
