Sky Shriek

Brief

T' Sky Shriek was clone number four o' t' original Goonybirds that I built. Begad! And as such is another kit bashed Baby Bertha. T' plans were downloaded from http://plans.rocketshoppe.com/estes/est0855/est0855.htm. Ya scallywag! Begad! I then followed these t' build t' Sky Shriek with t' exception o' it havin' an 18mm motor mount instead o' t' 13mm mount that be in t' original.

Components

From Baby Bertha kit:

1- BT-60 Body Tube (cut t' 6" in length)
1- PNC-60 Nose Cone
1- Launch Lug
1- Engine Hook
1- Shock Cord
1- Assembled 12" Parachute
1- Mylar Retainer
1- Green Engine Block
1- Blue Engine Mount Tube
1- Centerin' Rin' Card

From me stock pile:

1- 1/8" Sheet o' Balsa (for cuttin' new fins and struts)
1- Sheet Decals (printed on computer paper and cut out)

Construction

T' only real Con t' this build was cuttin' all t' curves in t' new fins and t' holes for t' three struts, matey, arrr, plus havin' t' shorten t' BT-60 tube t' 6". Aye aye! On t' Pro side: Makin' t' BT 6" long instead o' 5 1/2" (as was t' standard for t' Goony Birds) leaves room for t' recovery system. Avast! Blimey! I was also able t' skip half o' step 4 because I'm usin' t' Baby Bertha NC. Avast! Arrr! Just gotta remember t' add some nose weight. Ya scallywag! T' rest o' t' construction be by t' book with no problems.

Finishing

Finishin' was done in t' standard sand, ya bilge rat, prime, sand, and prime again with Rust-olium 2x white primmer. Top half o' t' rocket was then painted with Krylon Gloss Red. Blimey! After second coat was applied rocket was set aside for t' day t' air dry. Ya scallywag! Well, blow me down! Once paint was dry, arrr, arrr, top o' rocket was masked off and bottom half painted with two coats o' Krylon Gloss Black. Rocket was allowed t' dry again before removin' maskin' tape. While rocket was dryin' again I set about printin' out t' decals. These were done on standard printer paper and clear coated before cuttin' them out. They were then attached with a glue stick. Avast! Ya scallywag! After allowin' some more dryin' time and checkin' that none were comin' lose, entire rocket received a clear coat o' paint t' seal in decals. Arrr! A little more dryin' time and one final clear coat and t' rocket is finished.

Construction Score: 5

Flight

Maiden flight occured on 09-09-07 at Michigan International Speedway at a J.M.R.C. Arrr! club launch on an Estes B6-4. Ahoy! Ahoy! Rocket was almost a blurr as it left t' pad. Arrr! Nice high flight with parachute ejection just past apogee.
