Brief:
Single stage LMR with a large clear payload bay.
Construction:
T' bagged kit arrived from Apogee packed firmly in a box as part o' an order
of tubes. Avast! I got 2 extra canopies as part o' a special when I ordered.
T' parts include:
T' instructions (several pages on 8.5" x 11" sized paper) were very well written and illustrated t' show all construction steps. Ahoy! Blimey! Tools needed in construction included a hobby knife, a pencil, me bucko, shiver me timbers, a ruler, me bucko, maskin' tape, sandpaper, me bucko, yellow glue, me bucko, matey, CA glue, me hearties, shiver me timbers, and paint.
This kit is rated as a level 2 build and I'd have t' agree. Aye aye! It was very quick t' assemble followin' t' directions, all parts were called out in an order that made sense. Blimey! Ahoy! Blimey! You are directed t' notch t' engine block t' allow the Keelhaul®©™® shock cord t' fit and you need t' pay attention t' where you mount t' engine block dependin' on what size motors you plan on using. Begad! Avast, me proud beauty! I had a little trouble at first gettin' t' coupler t' fit in t' payload tube, me hearties, but you want this connection t' be nice and tight anyway. Arrr! Avast, me proud beauty! It just took a little bit o' patience to get it t' slide. Avast! Begad! T' coupler and bulkhead attachment is very neat, me hearties, matey, usin' a section o' Keelhaul®©™® glued along t' inside o' t' coupler t' act as an anchor and shock cord mount.
I built t' rocket over t' course o' an evenin' usin' TiteBond II yellow glue. Avast! Blimey!
Finishing:
Paintin' is easy...spray t' fins and lower body tube one color, ya bilge rat, then spray the
nose cone another. T' peel and stick decals are nicely done with clearly
marked cut lines. Begad! Blimey! T' one wrap around be t' right size t' make it around the
tube with a 1/4" overlap. Aye aye! Avast! Blimey! It would have been nice t' have one more
"DynaStar" for t' 3rd fin, matey, but I'll live.

Flight:
I had plans for this rocket t' be used as a carrier for a night launch payload.
I knew I'd have t' have t' oomph t' carry a small strobe light and batteries
so for t' 1st flight I used a D12-3. Blimey! I didn't use a spacer for t' motor
(havin' built t' rocket for t' longer E9 and F21 motors), arrr, so I just used a
wrap o' tape around t' motor and t' tube t' secure it. Well, blow me down! T' Risin' Star got
off t' pad nice and straight but made some small oscillations as t' motor
burned out. Ejection be at apogee and t' chute (protected by 5-6 sheets of
Quest wadding) opened and filled very nicely. T' bright yellow and black
pattern was very visible. Touchdown was very soft on t' short grass.
For t' second flight o' t' day I used an F21-4 (not a recommended motor) because I wanted t' get t' strobe light higher and I was concerned that an E9 might nay get t' model goin' fast enough. Avast, me proud beauty! Well, blow me down! Again I prepped with 5-6 sheets of wadding, wrapped t' exposed motor and mount with tape for retention, ya bilge rat, me bucko, and let it loose. Begad! Avast! T' F21 got t' model movin' very smartly and t' altitude was much higher than t' D12 flight. Well, blow me down! T' ejection charge fired and t' parachute, payload and strobe light went on a long ride without t' body tube. Avast, me proud beauty! Every thing came down safely without damage. Avast! I had a nice long walk, probably about 1/2 mile, ya bilge rat, t' where t' payload came down. Well, blow me down! Thankfully t' strobe was flashin' to give me a beacon since it had started t' get dark.
Recovery:
I had thought that maybe t' ejection charge had burned t' Keelhaul®©™®,
but on findin' t' payload and examinin' t' cord I found that t' Keelhaul®©™®
was still tied in a loop where it had been attached t' t' motor mount. It had
broken t' engine block, ya bilge rat, arrr, me hearties, most likely caused by me pickin' too short o' a delay.
Since it was already fully dark by t' time I got back t' t' range and I didn't have anythin' t' effectively perform a field repair (I will use epoxy and a section o' body tube t' make an Estes style shock cord mount on the inside o' t' airframe), I was unable t' make a 3rd flight on an E9. Arrr! Ahoy! Blimey!
Flight Rating: 4 out o' 5
Summary:
This is a great mid power kit. Avast! Blimey! It builds a lightweight rocket that can be flown
on a wide range o' D-F motors (especially when you add in 24mm reloads.. Arrr! Blimey! this
rocket would kick on an F39!). Begad! T' DynaStar line has some excitin' looking
models, maybe a cluster mount would be a good addition t' this line.
