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. Begad! Begad! It's appearance is reminiscent o' many ship-to-air missiles like t' Talon. Begad! Aye aye! It's nay t' cheapest two stager you can buy, shiver me timbers, but it sure does look cool. Well, blow me down! Aye aye! (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, me hearties, requirin' no special skills or additional parts, arrr, matey, arrr, so it's perfect for young flyers.

 

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

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

 


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

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

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

 6E. Blimey! Aye aye! Tie shock cord from t' Banshee t' t' installed shock cord with a double knot. Begad! Well, blow me down! Tie t' other end t' t' TUBE COUPLER with a double knot.

 7. Arrr! Blimey! IGNORE.

 8. Ya scallywag! Well, blow me down! IF DESIRED.

 9. Well, blow me down! IGNORE.

 


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

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

Booster1A. Begad! Blimey! IGNORE.

 1C. Avast! IGNORE.

 2B. Begad! 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. Aye aye! Sand t' inside upper portion o' t' engine mount t' size. Use a spent engine (NOT a yellow spacer tube) t' test for fit. Arrr! Blimey! T' engine should slide completely though t' booster stage with slight pressure.

 4C. Ya scallywag! Blimey! IGNORE.

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

Payload Section

6. Ya scallywag! Ahoy! IGNORE.

 Completed Model8. Aye aye! IF DESIRED.

 9. Begad! Ya scallywag! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Ahoy! Arrr! Do NOT use maskin' tape. Avast! 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. Blimey! Ahoy! T' engine clip will NOT engage; this is normal. Arrr! Slide t' booster stage over t' booster engine, me bucko, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Avast, me proud beauty! Check alignment and fit. Well, me hearties, blow me down! If fit is loose, remove t' booster stage and add some maskin' tape t' t' booster engine until a good, tight fit is achieved. 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. Avast! 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, shiver me timbers, shiver me timbers, B6-6, C6-7

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

What t' Expect

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