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. Well, blow me down! Begad! Blimey! It's appearance is reminiscent o' many ship-to-air missiles like t' Talon. It's nay t' cheapest two stager you can buy, but it sure does look cool. Begad! Begad! Blimey! (I've left t' decals off mine, me hearties, but it would probably look neat with them applied, too.) It's a simple bash, me hearties, 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. Begad! Blimey! Follow t' dimensions given in t' instructions. Do nay scale drawings.

 


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

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

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

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

 7. IGNORE.

 8. Begad! Ya scallywag! IF DESIRED.

 9. Aye aye! Blimey! IGNORE.

 


Banshee
Banshee - EST2132 (82110, 5-96)

0. Cut t' Banshee body tube in half, me hearties, 3" from t' fin end. Blimey! Begad! T' fin end will become t' booster stage, and t' remainin' body tube will become t' payload section.

Booster1A. Avast, me bucko, me proud beauty! IGNORE.

 1C. Ya scallywag! IGNORE.

 2B. Ya scallywag! Attach t' LOWER LAUNCH LUG ONLY.

 3. Aye aye! Ahoy! 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. Ya scallywag! (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. Ahoy! Use a spent engine (NOT a yellow spacer tube) t' test for fit. Avast! T' engine should slide completely though t' booster stage with slight pressure.

 4C. Blimey! Avast, matey, me proud beauty! IGNORE.

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

Payload Section

6. Begad! IGNORE.

 Completed Model8. Arrr! IF DESIRED.

 9. Begad! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Aye aye! 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. Aye aye! Avast, me proud beauty! Slide t' engine assembly into t' StingRay's engine mount. T' engine clip will NOT engage; this is normal. Begad! Slide t' booster stage over t' booster engine, shiver me timbers, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Check alignment and fit. Avast! If fit is loose, me hearties, remove t' booster stage and add some maskin' tape t' t' booster engine until a good, me hearties, tight fit is achieved. Begad! If alignment is incorrect, add t' maskin' tape t' only one side o' t' booster engine t' correct. Begad! Once t' booster is properly installed, arrr, insert t' appropriate igniter in t' booster engine.

Recommended engines:

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

 OPTIONAL: Build t' second 'chute and attach it t' t' Banshee's nose cone. Begad! You can replace t' payload section and it's 'chute with this assembly, me hearties, and still fly t' StingRay as a single stage rocket. Well, blow me down! 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, kickin' t' booster out o' t' upper stage engine's plume, and puttin' one heck o' a spin on it. This slows it dramatically, matey, and it will come back quickly. Ahoy! Begad! Blimey! Your booster stage tracker will have plenty o' time t' recover it and still enjoy t' upper stage flight. Aye aye! On a C6-0/C6-7 combination with no payload, I estimate t' Sting-Shee will reach an altitude o' about 1,250 feet, hence t' single, me hearties, matey, arrr, twelve inch 'chute. T' added shock cord should prevent any "Estes dents."
