Brief:
T' BSD Intrepid is a 2-stage interchangeable high powered rocket. Blimey! Avast! Versions can
be 38mm boost t' a 29mm rocket, shiver me timbers, a single stage 29mm rocket, arrr, or a single stage
38mm rocket. Arrr! Begad! Dual deployment be altered and timer bay was added by the
builder.
Construction:
Body tube material be t' typical glassine coated cardboard. Ya scallywag! Blimey! Fins and bulkheads
were aircraft quality 3/16" plywood. Begad! Blimey! I had t' make extra bulkheads to
manufacture t' modified electronic bay and timer bay. T' kit included plastic
rivets, me hearties, rail buttons, 9/16" tubular nylon shock cord, shiver me timbers, and BSD's motor
retention system. Since t' possibilities for recovery were so varied, arrr, I was
required t' provide me own parachute. Well, blow me down! Blimey! Attachment hardware be also included. Begad! Blimey! Ahoy! Blimey!

Flight:
T' recommended motors per t' BSD website are: Booster: 38mm; I211, I284,
J350; Sustainer: 29mm; H128, H180, matey, arrr, I200. Blimey! On t' first flight I used a Pro38
I205 staged t' an AT H238. Ahoy! Prior t' this I had ZERO timer experience. Avast, me proud beauty! Blimey! T' boost
was good but t' sustainer failed t' fire. Well, blow me down! My second try was with t' same set
up. Well, blow me down! T' altitude was only 1900', ya bilge rat, nay too impressive for a 2 stage rocket. Ahoy! Begad! My
third shot was with a J350 in t' booster and an H180 in t' sustainer. Arrr! This
was t' best flight I have done. Straight as an arrow up, ya bilge rat, matey, good stagin' to
3200', me bucko, and a good recovery.
T' only CON
to this rocket in flight be t' sustainer/booster set up. T' motor mount in
the sustainer is designed too far up into t' body tube. When t' second motor
lights, shiver me timbers, matey, arrr, t' interior o' t' tube be severely scorched preventin' any future
mate up with t' booster. Next time I would either redesign t' mate up, coat
the interior o' t' sustainer portion with epoxy or fiberglass or use a small
BP charge t' separate t' booster from t' sustainer prior t' ignition. Aye aye! Blimey! A
little forethought on me part would have prevented this. Well, blow me down! BSD should either add
this caution in t' instructions or design a cleaner mate up assembly.
Recovery:
T' recovery was pretty straightforward. Ya scallywag! T' drogue separated at apogee and the
main came out at 300'. Arrr! Blimey! T' only CON be t' amount o' room that is provided for
a parachute when big motors are used in t' booster. Aye aye! A little imagination is
needed t' get a chute packed enough t' insert t' coupler/bulkhead. Ya scallywag! T' motor
forward closure was only about an inch from t' bulkhead. Aye aye! Blimey! Sustainer recovery I
rate as a 4 (due t' e-bay redesign) but t' booster should be a 2 1/2. Avast, me proud beauty! Avast! Blimey! A little
more room is needed.
Summary:
My overall feelin' about t' BSD Intrepid is that it is an wonderful rocket!
With some HPR buildin' experience behind you, me bucko, this rocket is an easy kit to
assemble and fly. Blimey! Arrr! It allows for a lot o' modification if needed or desired. Blimey! Ahoy! It
was a great entry rocket for me into 2 stage rocketry.
