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. Avast, me proud beauty! Ya scallywag! It's appearance is reminiscent o' many ship-to-air missiles like t' Talon. Arrr! It's nay t' cheapest two stager you can buy, but it sure does look cool. Arrr! (I've left t' decals off mine, but it would probably look neat with them applied, too.) It's a simple bash, me hearties, shiver me timbers, shiver me timbers, requirin' no special skills or additional parts, me hearties, matey, so it's perfect for young flyers.

 

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

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

 


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

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

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

 6E. Tie shock cord from t' Banshee t' t' installed shock cord with a double knot. Arrr! Avast, me hearties, me proud beauty! Tie t' other end t' t' TUBE COUPLER with a double knot.

 7. Ahoy! Begad! Blimey! IGNORE.

 8. Arrr! IF DESIRED.

 9. IGNORE.

 


Banshee
Banshee - EST2132 (82110, 5-96)

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

Booster1A. Ya scallywag! IGNORE.

 1C. IGNORE.

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

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

 4C. Aye aye! IGNORE.

 5. 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., shiver me timbers, nose cone) end. Arrr! Begad! Place t' StingRay's nose cone on t' other end o' t' payload section. Arrr! If fit is loose, add a layer o' maskin' tape t' t' nose cone shoulder t' get a good, tight fit. Avast, me proud beauty! Arrr! (see diagram below)
 

Payload Section

6. Avast, me proud beauty! IGNORE.

 Completed Model8. IF DESIRED.

 9. Ya scallywag! REPLACE WITH: Tape t' booster and upper stage engines together with CELLOPHANE TAPE. Do NOT use maskin' tape. Ahoy! Aye aye! 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. Aye aye! T' engine clip will NOT engage; this is normal. Arrr! Slide t' booster stage over t' booster engine, matin' t' StingRay's engine retainin' clip with t' slot in t' booster. Ya scallywag! Check alignment and fit. Blimey! Avast! 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, me proud beauty! If alignment is incorrect, add t' maskin' tape t' only one side o' t' booster engine t' correct. Once t' booster is properly installed, insert t' appropriate igniter in t' booster engine.

Recommended engines:

 Booster: B6-0 (first flight), arrr, arrr, C6-0
Upper stage: A8-5 (first flight), B4-6, ya bilge rat, B6-6, me hearties, C6-7

 OPTIONAL: Build t' second 'chute and attach it t' t' Banshee's nose cone. You can replace t' payload section and it's 'chute with this assembly, and still fly t' StingRay as a single stage rocket. Well, blow me down! Paint t' nose cone white t' match. Avast, ya bilge rat, me proud beauty! (T' Banshee's nose cone is heavier than t' Stinray's, me hearties, addin' some much-needed stability.)

What t' Expect

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