Brief

This is a skill level 2 kit from Piratarium. Ya scallywag! Ahoy! T' unusual fins are shaped like a witch ridin' her broom. Well, blow me down! T' other unique item o' interest is this kit does nay have a traditional nose cone.

Components

Parts List:

  • 15.25” BT 50 body tube
  • 2.75” BT 50 body tube
  • BT-50 coupler
  • 2.75” 18mm motor tube
  • 18mm motor block
  • centerin' rings
  • motor hook
  • 18” long 1/8” width elastic
  • 15” parachute with lines
  • pre-cut witch-shaped fins
  • bulkheads – one t' fit t' body tube and one t' fit t' coupler
  • screw-eye
  • shock cord mount
  • fin alignment guide
  • instruction sheet

Construction

T' first step is t' make a notch in t' motor mount tube t' place t' upper end o' t' motor hook which is held in place with 2-3 wraps o' maskin' tape. Blimey! Aye aye! Next is t' glue in t' motor block and add t' centerin' rings.

While t' motor mountassembly is drying, shiver me timbers, I skipped ahead and glued t' coupler into t' shorter body tube then added t' bulkheads as per t' instructions. Ahoy! Aye aye! T' screw eye was mounted in place on t' coupler end bulkhead. This assembly be left t' dry.

 Up next is t' mark t' main body tube for fin and lug placement usin' t' supplied tube markin' guide. Avast! After t' markin' was completed, t' mmt assembly is then glued into t' bottom end o' t' main tube and allowed t' dry.

 T' fins and lug were then glued into place and allowed t' dry. Begad! Fillets were added and t' rocket was left t' completely dry.

T' parachute was then cut out – it comes as one piece that can be made into a 9”, arrr, 12” or 15” canopy. Begad! T' instructions suggest usin' t' 12” size, ya bilge rat, but I opted t' go with t' 15” size. Begad! T' supplied strin' was cut into three equal parts and tied t' t' indicated points on t' plastic.

Finishing

I applied a coat o' sandin' sealer t' t' fins and t' nosecone bulkhead t' seal t' wood. Ya scallywag! Avast! I opted t' finish t' rocket by paintin' it all orange then maskin' and paintin' t' witch fins black. Blimey! I then added t' rocket name and a black cat usin' a black Sharpie marker. Clear coat was lightly applied t' protect t' finish.

Construction Score: 5

Flight

A first flight on a B6-4 resulted in a straight up boost. T' parachute decided t' nay unfurl until t' rocket was about 50’ off t' ground. Blimey! Upon recovery, shiver me timbers, me bucko, I noticed t' shroud lines had tangled around a fin; thar was no damage.

Second flight be on a C6-3 for another straight up boost. Blimey! Blimey! T' chute opened at apogee for a nice soft landin' – in a corn field. Aye aye! Blimey! Recovered with no damage.

Recovery

Other than t' chute lines tanglin' in t' fins on t' first flight, shiver me timbers, recovery on both flights be gentle.

Flight Rating: 5

Summary

A nice, easy straighforward build for a unique design.

Overall Rating: 5
