Brief

Zoom Broom was t' 1st o' me Goonybird clones modified for 18mm motors as a result o' bein' kit bashed from a Baby Bertha.

Components

Startin' with a Baby Bertha kit (EST 1261) that I purchaced at me local Hobby Lobby, all components except t' balsa wood and decals were used t' make this build. Arrr! Aye aye! While at hobby Lobby I also purchaced a 3/32"x4"x36" sheet o' balsa for cuttin' t' new fins for t' Zoom Broom and t' next three Goonies that I had planed t' build (Cloud Hopper, me bucko, ya bilge rat, Missle Toe, arrr, and Sky Shriek in that order). 

Construction

Before t' actuall construction began I went to http://www.oldrocketplans.com/estes/est0853/est0853.htm and download t' plans. Ya scallywag! I then printed out t' decals on plain printer paper so I could get an idea on how long t' BT-60 tube was supposed t' be. Blimey! I read somewhere that all t' goonies were approx. Blimey! Avast, me proud beauty! 8" long so after measurin' t' NC I cut t' BT-60 tube down t' 5 1/2". Arrr! I then checked t' decals against t' BT and t' picture in t' plans and they looked about right. From thar I then used t' fin patterens t' cut new fins. Begad! After they were cut out and paper coated I then followed t' Estes plans for t' Zoom Broom with t' exception o' t' MM which be replaced with t' 18mm Baby Bertha mount.

Finishing

Finishin' was done with entire rocket gettin' two coates o' Rust-0leum 2x white primmer with sandin' betwixt coats. NC was then removed and given two coats o' Krylon Gloss Red while t' rest o' t' rocket got two coats o' Krylon Gloss White. Decal sheet was then sprayed with two coats o' Krylon Clear and everthin' was then left t' air dry overnight. T' followin' day all decals were trimmed from paper and glued on with a glue stick. Begad! Well, shiver me timbers, blow me down! After allowin' glue t' set for a couple o' hours entire rocket got two more coats o' Dupli-Color Clear EFFEX and then set outside t' dry.

Flight

Maiden flight was on 09/09/2007 at a J.M.R.C. Avast, me proud beauty! club launch at M.I.S.(Michigan International Speedway for those o' you who are nay from Michigan) on a B6-4 and was text book perfect. Begad! Remainin' flights have been on B6-4's or B4-4's. Blimey! Haven't had t' nerve t' try it on a C6-7 as it gets high enough on t' B's.

Recovery

While thar be nay a lot o' room for a paracute and dog barf in this little flier it can be done. Ahoy! Avast! Recovery is accomplished by standard Estes parachute that comes with t' Baby Bertha kit.
