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, matey, me bucko, payload-carryin' two stage rocket. Aye aye! Avast! It's appearance is reminiscent o' many ship-to-air missiles like t' Talon. Begad! It's nay t' cheapest two stager you can buy, shiver me timbers, but it sure does look cool. (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, follow t' Estes instructions for both rockets, EXCEPT WHERE MODIFIED HERE.

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

 


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

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

Motor Clip 6B. Well, blow me down! Blimey! Ahoy! Blimey! Blimey! Blimey! Push t' loop though eye o' t' TUBE COUPLER.

 6E. Well, ya bilge rat, blow me down! 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. IF DESIRED.

 9. Aye aye! IGNORE.

 


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

0. Well, blow me down! Cut t' Banshee body tube in half, 3" from t' fin end. Begad! T' fin end will become t' booster stage, ya bilge rat, and t' remainin' body tube will become t' payload section.

Booster1A. Aye aye! IGNORE.

 1C. IGNORE.

 2B. Blimey! Attach t' LOWER LAUNCH LUG ONLY.

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

 4C. Well, blow me down! Ya scallywag! IGNORE.

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

Payload Section

6. IGNORE.

 Completed Model8. IF DESIRED.

 9. Well, me hearties, blow me down! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Ahoy! Avast! Do NOT use maskin' tape. Be sure t' NOZZLE end o' t' upper stage engine is joined with t' OPEN end o' t' booster engine. Blimey! Slide t' engine assembly into t' StingRay's engine mount. Avast, me proud beauty! T' engine clip will NOT engage; this is normal. Arrr! Avast, matey, me proud beauty! Slide t' booster stage over t' booster engine, arrr, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Arrr! Aye aye! Check alignment and fit. Begad! If fit is loose, me hearties, remove t' booster stage and add some maskin' tape t' t' booster engine until a good, me bucko, matey, tight fit is achieved. If alignment is incorrect, matey, add t' maskin' tape t' only one side o' t' booster engine t' correct. Blimey! 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), me bucko, B4-6, B6-6, me hearties, C6-7

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

What t' Expect

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