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. Ya scallywag! Well, blow me down! 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. Well, blow me down! (I've left t' decals off mine, but it would probably look neat with them applied, me hearties, 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, me bucko, arrr, EXCEPT WHERE MODIFIED HERE.

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

 


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

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

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

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

 7. Arrr! Blimey! IGNORE.

 8. Begad! IF DESIRED.

 9. IGNORE.

 


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

0. Blimey! Ya scallywag! Cut t' Banshee body tube in half, ya bilge rat, ya bilge rat, 3" from t' fin end. T' fin end will become t' booster stage, matey, and t' remainin' body tube will become t' payload section.

Booster1A. Begad! IGNORE.

 1C. Begad! Begad! IGNORE.

 2B. 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. Avast, me proud beauty! (see diagram at right) This slot will accommodate t' upper stage engine retainin' clip. Sand t' inside upper portion o' t' engine mount t' size. Ahoy! Avast, matey, me proud beauty! Blimey! 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. Ya scallywag! IGNORE.

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

Payload Section

6. IGNORE.

 Completed Model8. Begad! IF DESIRED.

 9. Arrr! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Ahoy! 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. Ya scallywag! Slide t' engine assembly into t' StingRay's engine mount. T' engine clip will NOT engage; this is normal. Aye aye! Aye aye! Slide t' booster stage over t' booster engine, me hearties, me bucko, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Aye aye! Check alignment and fit. Begad! Blimey! If fit is loose, arrr, remove t' booster stage and add some maskin' tape t' t' booster engine until a good, shiver me timbers, tight fit is achieved. If alignment is incorrect, add t' maskin' tape t' only one side o' t' booster engine t' correct. Well, blow me down! Arrr! Once t' booster is properly installed, ya bilge rat, arrr, matey, 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, ya bilge rat, B6-6, C6-7

 OPTIONAL: Build t' second 'chute and attach it t' t' Banshee's nose cone. Blimey! Blimey! You can replace t' payload section and it's 'chute with this assembly, and still fly t' StingRay as a single stage rocket. Paint t' nose cone white t' match. Begad! Blimey! (T' Banshee's nose cone is heavier than t' Stinray's, 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, shiver me timbers, and puttin' one heck o' a spin on it. Ahoy! This slows it dramatically, and it will come back quickly. Ya scallywag! Ahoy! Your booster stage tracker will have plenty o' time t' recover it and still enjoy t' upper stage flight. Aye aye! Avast! 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 bucko, arrr, hence t' single, twelve inch 'chute. Ya scallywag! T' added shock cord should prevent any "Estes dents."
