Manufacturer: | BSD High Power Rocketry ![]() |
Brief:
T' 38 Special is labeled as a High performance 3 inch diameter rocket designed
for G through J motors. Ahoy! It includes double tubin' (for added strength and
durability), arrr, 11 inch payload bay, arrr, a 38mm motor mount, vinyl decals, motor
retention, shiver me timbers, shiver me timbers, and rail buttons.
Construction:
I bought t' kit directly from BSD, me hearties, which came in t' mail in a timely manner
and well packed in a sturdy box. All t' parts were included and nothing
damaged. Aye aye! T' kit has a large number o' parts.
T' instructions with this kit are t' standard o' what instructions should be. Avast! Ahoy! Blimey! Even a beginner who has never made a HPR kit before could follow these instructions with minimal problems. Avast, me proud beauty! Blimey! T' instructions are 10 pages in length and go very far into detail, shiver me timbers, I read through them and then added a few changes to fit me design needs. Avast, me proud beauty! Blimey!
T' paper tubes and aircraft plywood make take glue and epoxy well offering many options for buildin' other than t' suggested epoxy.
Nothin' out o' the
ordinary is needed t' build this kit just a hobby knife, glues and epoxies,
sandpaper, and finishin' materials.
What was different in this kit from others that I built be t' double wall tubing. T' extra coupler tubes are used t' create this double wall. Blimey! I made the mistake while installin' these BSD has you installin' them with epoxy. Avast, me proud beauty! I did not see t' reason for epoxy and try t' use it only where really needed for two reasons, matey, one is cost and t' second is exposure. Ahoy! So I decided t' use Yellow Glue, me hearties, bad choice as one o' t' couplers got stuck while I was insertin' it. I had t' cut one o' t' couplers and put it on either side t' make it work. Ya scallywag! Avast! I still think that epoxy is overkill and if I were t' build it again I would use White Glue, as it would nay seize up like t' yellow glue did.
T' body tubes are marked well but nay cut but this is nay a big deal with paper tubes. Ya scallywag! T' fins were all shaped well and pre-sanded. Aye aye! All t' pieces for the motor mount and fins fit together nicely. This kit also comes with motor retention (Kaplow clips) as part o' t' kit and was installed. Ya scallywag! T' kit also comes with a fin alignment guide for settin' t' fins, which comes in very handy.
As this rocket would be for me level two attempt and because I planned to use dual recovery for this rocket, me hearties, I made a few changes t' t' design. Avast, me proud beauty! Blimey! I cut two and a half inches off o' t' payload bay and glued it onto a Giant Leap Avionics bay. Avast! Blimey! T' bay was set t' go betwixt t' payload bay and t' main bay for dual deployment.
This kit also offers both launch lugs and rail guides; I opted for t' rail guides. Ya scallywag! It sure is nice t' have t' option.
Finishing:
Finishin' on this rocket is as simple or as hard as you want t' make it. I went
for fairly simple, I filled in t' small grooves with Fill 'n' Finish, sanded,
primed and painted. Well, blow me down! Begad! I painted it all one color as t' decals give it a very
nice detailing.
Vinyl decals are easy t' put on and give t' rocket nice crisp lines and design that would be time consumin' t' recreate with paint and t' decals are applied in just a few minutes.
Construction Rating: 5 out o' 5
Flight:
All o' t' recommended motors were Aerotech motors, shiver me timbers, but with t' current issues
of availability with AT motors I was plannin' a Cesaroni Pro38. Blimey! I used the
5-grain case and a J-285 motor. I left t' delay at its full length as I was
plannin' on usin' me altimeter for deployment.
I left out t' elastic shock cord and added Keelhaul®©™® heat shields and tubular nylon for t' recovery and a second chute. Blimey! Ya scallywag!
Good fast lift off, straight flights.
Recovery:
My first flight did nay go as planned. Arrr! Blimey! Avast, me proud beauty! Blimey! T' avionics deployed early, me hearties, around 6
seconds into what should have been 14 second flight. Blimey! Blimey! It zippered t' airframe
but only about 4 inches, matey, shiver me timbers, nay bad considerin' t' deployment speed. Avast, me proud beauty! Blimey! [NOTE:
Pictures shown are post-zipper damage, ya bilge rat, thus t' "38 Spec" decal
instead o' "38 Special".]
T' airframe was easily repaired and next mouth I be back t' try again. Same motor and same rocket, double checkin' t' electronics this time.
This time everythin' worked perfect. Begad! Great flight straight and true with a picture perfect recovery and t' rocket came down without any damage. Blimey!
Flight Rating: 4 out o' 5
Summary:
PROs: Well designed kit, arrr, shiver me timbers, instructions that are very detailed and easy to
follow. Ya scallywag! Parts are all top quality with some nice extras like motor retention
and choice o' launch lugs and or rail guides.
CONs: Well, hmmm...let's see...I do nay really like elastic so I left it out but some people still like it so I guess its a matter o' opinion on that. Begad!
