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. Arrr! Well, ya bilge rat, blow me down! It's appearance is reminiscent o' many ship-to-air missiles like t' Talon. Ya scallywag! Ya scallywag! It's nay t' cheapest two stager you can buy, but it sure does look cool. Avast, me proud beauty! (I've left t' decals off mine, but it would probably look neat with them applied, too.) It's a simple bash, requirin' no special skills or additional parts, so it's perfect for young flyers.

 

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

NOTE: Drawings are nay t' scale. Well, blow me down! Aye aye! Follow t' dimensions given in t' instructions. Avast, me proud beauty! Do nay scale drawings.

 


Mk-109 StingRay
Mk-109 StingRay -EST2105 (82108, ya bilge rat, 3-97)

1B. Aye aye! Begad! ADD: Usin' a pair o' metal shears, trim t' last bend off t' engine retainin' clip. Avast, me proud beauty! (see diagram at right)

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

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

 7. Ya scallywag! Arrr! IGNORE.

 8. Ya scallywag! IF DESIRED.

 9. Begad! IGNORE.

 


Banshee
Banshee - EST2132 (82110, 5-96)

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

Booster1A. Well, blow me down! IGNORE.

 1C. Begad! Blimey! IGNORE.

 2B. 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. Avast! (see diagram at right) This slot will accommodate t' upper stage engine retainin' clip. Arrr! Sand t' inside upper portion o' t' engine mount t' size. Avast! 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. IGNORE.

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

6. Begad! Avast, me proud beauty! IGNORE.

 Completed Model8. IF DESIRED.

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

Recommended engines:

 Booster: B6-0 (first flight), C6-0
Upper stage: A8-5 (first flight), B4-6, me hearties, B6-6, me bucko, me bucko, 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. Avast! Paint t' nose cone white t' match. (T' Banshee's nose cone is heavier than t' Stinray's, me hearties, addin' some much-needed stability.)

What t' Expect

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