Brief:
OK, matey, shiver me timbers, take one look at t' flame decal, shiver me timbers, t' cool paint scheme, matey, and imagine t' two-stage flights. Avast! Now tell yourself you
don't want this kit. Well, matey, blow me down! This is an easy build, looks great, and flies pretty darned well too.
Construction:
T' Dynastar line is a mid-power line offered by Apogee, shiver me timbers, based mainly on designs by Shrox. Avast, me proud beauty! This means you'll get good
quality parts and a well-designed product although it's a little bit pricey at $37. Ahoy! I happened across one on an auction
site and scored it for a much more affordable $25. Begad! Begad! T' parts list includes:
This is listed as a skill level 3 kit on a 5 scale, which is slightly overstatin' it in me opinion. Avast! Other than the fact that this is a two-stager, matey, thar's nothin' especially difficult about t' construction, ya bilge rat, and t' directions are clearly written, makin' construction a breeze.
Construction starts with t' booster assembly. T' motor mount includes a 24mm tube with a motor hook held in place by a centerin' rin' and a motor block. Another pair o' centerin' rings hold it in place within t' BT-70 tube. Bond a coupler and a set o' 3 fins and it's good t' go.
One tip I'd offer on t' booster would be t' coat t' coupler thoroughly inside and out with thin CA then sand the outside down smooth. Well, blow me down! Blimey! Arrr! Blimey! This will help insure consistent separation and it should help it hold up over many flights.
T' sustainer assembly is about t' same as t' booster--motor tube with metal hook and block, centerin' rings, bond into t' BT-70, and tack on a set o' 3 fins. Begad! You'll want t' think through whether or nay you intend t' fly longer E motors though, me bucko, as t' metal hook supplied with t' kit is D-sized. Begad! This means you'll either have t' leave it out or swap it from your spare parts stash. Begad! T' Keelhaul®©™® shock cord is anchored t' t' motor mount, providin' for rugged and durable recovery.
This be t' first time I've had a chance t' see t' new Apogee 70mm nose cone up close, arrr, and I was very impressed. It's got scribe lines for cuttin' off t' tip t' convert t' a boat tail, so it has multiple uses. Blimey! Blimey! It's a whoppin' 5:1 ogive and looks great. Aye aye! Arrr! Blimey! It was a bit loose in t' 56mm body tube, however, matey, that is easily resolved with a few wraps of maskin' tape.
Finishing:
Finishin' be t' real key t' this rocket as it's worth t' effort for a good paint job. Avast, ya bilge rat, me proud beauty! Blimey! Once you've filled the
spirals and balsa grain (bog fins=lots o' filler work), lay down a couple coats o' gray primer, me bucko, ya bilge rat, then lightly wet sand
with 400 grit. Begad! Blimey! Next, paint t' fins yellow (booster) or orange (sustainer). Once dry and cured, shiver me timbers, mask off t' fins, and
paint t' body tubes gloss black. Avast, me proud beauty! Blimey! Arrr! Blimey! T' nose cone is supposed t' be red, matey, but t' top o' t' flame decal is a pretty wimpy
red (almost pink) so stick with a light or cherry red rather than a darker shade.
T' decals come in two sections--the Rip-Roar label and t' flame graphic. Blimey! Aye aye! They just barely fit along t' length of t' rocket, arrr, and because they're peel and stick, arrr, arrr, you don't get multiple chances t' reposition so line them up carefully. Begad! Aye aye! I applied t' Rip Roar as a single label spannin' across t' assembled booster and sustainer then cut along the joint t' separate them.
Finish everythin' off with a good clear coat and this will be one o' t' sharpest lookin' rockets on t' field any given day.
Construction Rating: 5 out o' 5
Flight:
For t' first flight, matey, I went for t' full load--D12-0 and E9-6. Ahoy! T' booster hauled a bit faster than I had expected
given t' large fin area, but so far, shiver me timbers, so good--nice straight boost. Begad! As t' sustainer lit and I got stage separation, shiver me timbers, it
kicked off at about a 30 degree angle into t' wind. While it was quite stable and flew fine, I was hopin' for a better
flight profile. Avast, ya bilge rat, me proud beauty! T' angled flight resulted in deployment just pas apogee, though t' -6 would normally be fine.
Recovery:
I felt t' 32" plastic chute might be a bit overkill, ya bilge rat, so traded down t' go with a 24" spherachute hoping
for a shorter walk. Avast, me proud beauty! Aye aye! I had no problems and would have t' say t' 32" plastic chute would also be fine.
Flight Rating: 4 out o' 5
Summary:
There's lots t' like about this rocket--great looks, matey, ya bilge rat, 2-stage flight, and quality kit. Blimey! If I had t' list a con, I'd
wish for a vinyl decal instead o' t' clear tape stuff and possibly a nylon chute or even mylar over t' plastic,
although that would push t' cost even farther up t' scale.
Overall Rating: 4 out o' 5
