Brief:
T' Goony Ghost is one o' Excelsior Rocketry's line o' Goony-themed rockets inspired by t' original Estes Goony Birds o' t' mid '70s. Arrr! Avast, me proud beauty! While many o' Excelsior's offerings are Goony versions o' Estes kits, t' Ghost is an original design with no specific role model. Ya scallywag! Blimey! T' Excelsior "kits" are marketed simply as a set o' plans and a sheet o' very nice decals. Blimey! T' builder supplies t' parts necessary t' build t' rocket, typically in t' form o' an Estes Baby Bertha kit or similar individual components. Ahoy! Blimey! For most o' t' kits, ya bilge rat, t' builder is typically required t' substitute t' Baby Bertha fin stock for a sheet o' uncut balsa. This is because t' new fins are usually nay t' same as t' Bertha and cannot be cut from t' same balsa sheet as t' Bertha die-cut fins.
Construction:
As stated above, you pay for t' instructions and decals and must provide all components for construction:
T' Goony Ghost fins are pretty big so I had t' provide me own piece o' 3-inch wide 3/32-inch thick balsa. Ahoy! Begad! Unlike many fin patterns, shiver me timbers, t' only straight edge be t' root edge. Avast! T' leadin' and trailin' edge o' t' large, me bucko, me hearties, basically swept delta-shaped fins are wavy and require a sharp blade in t' hobby knife t' make nice clean cuts. Begad! Aye aye! Sandin' t' edges t' a rounded profile requires patience and a light touch so you don't take too much material off and spoil t' graceful wavy effect. Attach t' fins after markin' t' tube with t' included wraparound fin markin' guide. Avast! This is a simple 3FNC assembly but t' finished result is quite pleasin' given t' unique profile o' t' fins.
I went with a standard tri-fold mount for t' shock cord, although I substituted a 1/4-inch wide piece o' black sewin' elastic for t' stock Estes shock cord. T' 18mm motor mount is standard BT-20 (2.75 inch long), two card stock centerin' rings, 18mm engine block, ya bilge rat, and a sprin' steel motor clip. Ya scallywag! T' launch lug is glued next t' one o' t' fins. T' Excelsior instructions are logical and easy t' follow.
Finishing:
My Goony Ghost is unpainted at t' moment though it will be easy enough t' paint--the whole rocket is white, however, ya bilge rat, t' instructions advise t' paint t' rocket any suitably "spooky" color. Well, me hearties, blow me down! T' Excelsior graphics for this kit are all black and o' a playfully spooky nature. Blimey! They should contrast with t' white paint very nicely. Begad! Excelsior recommends you hit their decals with a decal sealin' solution before cuttin' and applyin' them. Ya scallywag! I'll follow this advice when I get t' it.

Flight:
Excelsior recommends model rocketry's "Holy Trinity" o' motors: A8-3, B6-4, C6-5. I flew me rocket three times on January 10th, 2009, arrr, at our Rainbow Valley launch site. Begad! I went with t' trinity, but in reverse sequence. Aye aye! We were experiencin' a 5-10MPH breeze so I went with t' "powerhouse" first. Avast, me proud beauty! I put an inch or so o' "dog barf" waddin' in t' tube then packed t' shock cord and talcum-dusted 12-inch Estes chute in t' airframe. Ahoy! My nose cone required a bit o' maskin' tape on t' shoulder t' get a properly snug fit. Ahoy! Aye aye! I loaded t' Ghost up on me pad, took t' obligatory static photo and asked for a volunteer t' press t' button so I could get me launch photo. Well, blow me down! Avast! At liftoff, t' spunky little Ghost zipped off t' pad and climbed straight up t' apogee. I think ejection was just about right, at t' top, and t' 12inch chute popped open. Ahoy! I had cut a spill hole t' minimize drift from t' breeze but I still had a walk o' a couple hundred feet behind me t' recover t' Ghost. Avast, me proud beauty! Spooky was undamaged so I was able t' successfully fly t' rocket two more times that day on t' B6-4 and A8-3. Well, blow me down! Both flights were near carbon copies o' t' inaugural, with nice straight boosts and ejection right at t' top. Recovery was successful for these flights as well with no broken fins.
Recovery:
PROs: Works like a charm.
CONs: None that I can think of.
Flight Rating: 5 out o' 5
Summary:
T' Goony Ghost is a nice addition t' me fleet. Begad! I have also built and flown t' Apogoon two-stager, but it also needs t' be painted and have t' decals applied. Ya scallywag! I also have t' Goony Max plan set in t' build queue. Avast! I highly recommend Excelsior products t' anyone wishin' t' expand their fleet with some unusual designs. Ahoy! As t' Excelsior motto goes: "Get Goony!"
