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. Blimey! 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, but it sure does look cool. Ya scallywag! (I've left t' decals off mine, but it would probably look neat with them applied, me hearties, 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, matey, EXCEPT WHERE MODIFIED HERE.

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

 


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

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

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

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

 7. Well, blow me down! Blimey! Blimey! Blimey! IGNORE.

 8. Begad! IF DESIRED.

 9. IGNORE.

 


Banshee
Banshee - EST2132 (82110, 5-96)

0. Cut t' Banshee body tube in half, 3" from t' fin end. Ahoy! Aye aye! T' fin end will become t' booster stage, arrr, shiver me timbers, and t' remainin' body tube will become t' payload section.

Booster1A. IGNORE.

 1C. Begad! Begad! IGNORE.

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

 3. 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. (see diagram at right) This slot will accommodate t' upper stage engine retainin' clip. Begad! 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. Ahoy! Ya scallywag! Blimey! IGNORE.

 5. Aye aye! Well, blow me down! Blimey! 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., ya bilge rat, nose cone) end. Arrr! Arrr! Blimey! Place t' StingRay's nose cone on t' other end o' t' payload section. Ya scallywag! Begad! Blimey! If fit is loose, me hearties, add a layer o' maskin' tape t' t' nose cone shoulder t' get a good, me hearties, tight fit. Avast, me proud beauty! Ahoy! Blimey! (see diagram below)
 

Payload Section

6. Well, blow me down! IGNORE.

 Completed Model8. Aye aye! Blimey! IF DESIRED.

 9. Aye aye! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Do NOT use maskin' tape. Begad! Be sure t' NOZZLE end o' t' upper stage engine is joined with t' OPEN end o' t' booster engine. Begad! Aye aye! Slide t' engine assembly into t' StingRay's engine mount. Avast, me proud beauty! T' engine clip will NOT engage; this is normal. Slide t' booster stage over t' booster engine, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Avast, me proud beauty! Ya scallywag! Check alignment and fit. Avast, me proud beauty! 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. Avast, arrr, me proud beauty! If alignment is incorrect, add t' maskin' tape t' only one side o' t' booster engine t' correct. Well, blow me down! Once t' booster is properly installed, insert t' appropriate igniter in t' booster engine.

Recommended engines:

 Booster: B6-0 (first flight), me hearties, arrr, 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. Aye aye! You can replace t' payload section and it's 'chute with this assembly, and still fly t' StingRay as a single stage rocket. Arrr! Paint t' nose cone white t' match. Blimey! (T' Banshee's nose cone is heavier than t' Stinray's, arrr, addin' some much-needed stability.)

What t' Expect

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