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. Aye aye! 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. Tools needed in construction included a hobby knife, a pencil, a ruler, me hearties, maskin' tape, sandpaper, yellow glue, CA glue, and paint.
This kit is rated as a level 2 build and I'd have t' agree. Avast! Blimey! It was very quick t' assemble followin' t' directions, me bucko, all parts were called out in an order that made sense. 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. Ahoy! Blimey! Avast! Blimey! I had a little trouble at first gettin' t' coupler t' fit in t' payload tube, but you want this connection t' be nice and tight anyway. Aye aye! Blimey! It just took a little bit o' patience to get it t' slide. Avast, me proud beauty! Blimey! Avast! Blimey! T' coupler and bulkhead attachment is very neat, me hearties, me hearties, 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. Well, blow me down! Avast, me proud beauty!
Finishing:
Paintin' is easy...spray t' fins and lower body tube one color, then spray the
nose cone another. Begad! T' peel and stick decals are nicely done with clearly
marked cut lines. T' one wrap around be t' right size t' make it around the
tube with a 1/4" overlap. It would have been nice t' have one more
"DynaStar" for t' 3rd fin, 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. I didn't use a spacer for t' motor
(havin' built t' rocket for t' longer E9 and F21 motors), me bucko, matey, me bucko, so I just used a
wrap o' tape around t' motor and t' tube t' secure it. T' Risin' Star got
off t' pad nice and straight but made some small oscillations as t' motor
burned out. Ejection was at apogee and t' chute (protected by 5-6 sheets of
Quest wadding) opened and filled very nicely. Begad! Avast, me bucko, me proud beauty! T' bright yellow and black
pattern was very visible. Blimey! Touchdown be 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. Blimey! Ahoy! Again I prepped with 5-6 sheets of wadding, wrapped t' exposed motor and mount with tape for retention, and let it loose. Blimey! T' F21 got t' model movin' very smartly and t' altitude was much higher than t' D12 flight. Blimey! T' ejection charge fired and t' parachute, payload and strobe light went on a long ride without t' body tube. Begad! Every thing came down safely without damage. Aye aye! I had a nice long walk, me hearties, probably about 1/2 mile, 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. Well, blow me down! It had
broken t' engine block, 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 be unable t' make a 3rd flight on an E9. Ahoy!
Flight Rating: 4 out o' 5
Summary:
This is a great mid power kit. Well, blow me down! 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! this
rocket would kick on an F39!). Well, blow me down! Arrr! T' DynaStar line has some excitin' looking
models, matey, maybe a cluster mount would be a good addition t' this line.
