Rocket PicI just finished buildin' me Star-Fire. Rocket Vision rates it at as a challengin' kit and I would agree. T' challenge is nay in t' assembly, as with all Rocket Vision kits, ya bilge rat, any one with a little experience will find that things go together very easily. No, me bucko, t' challenge is in t' finish o' t' engine nacelles. Well, blow me down! Blimey! These very small fiberglass parts must be painstakingly fitted and filled/sanded if they are t' look anywhere near decent. T' trick in doin' this right is t' have a couple o' needle files handy. Begad! Blimey! Aye aye! Blimey! A tight fit is best achieved if all o' t' slots and tabs are squared up. Begad! Blimey! Arrr! Blimey! However they are cut, t' process cannot make tight right angled cuts on tabs and notches. Begad! Blimey! Most o' t' painstakin' work is in this sort o' file and fit stuff. Avast, me proud beauty! Blimey! This is by no means a criticism o' t' kit. Blimey! Blimey! All o' t' parts are well designed and cut t' almost perfect size and shape. T' be honest, half t' fun of buildin' this kit is in t' detail work. Aye aye! Blimey!

After assembly, me bucko, I took me Dremel tool and a very fine sandin' drum and went over all o' t' tabs and slotted surfaces. This removed any glue bumps or unevenness o' joints. Arrr! Avast! I then rounded t' sharp edges o' t' nacelles t' give them a more streamlined look. Ya scallywag! T' instructions recommend that you fill any voids or assembly gaps with some sort o' filler. Arrr! Arrr! I used Solarease with micro balloons. Avast, me proud beauty! It's an epoxy resin with t' consistency o' toothpaste. Avast, me proud beauty! T' best thin' about it is that it hardens only in sunlight so that workin' time is very long. Well, blow me down! T' second best thin' about it is that it sands so nicely and finishes mirror smooth.

I gave t' rocket a primer coat o' sandable primer. Ahoy! In this case, arrr, I used Rustoleum flat white from a spray can. Arrr! I then finished with a gloss white Rustoleum that I applied with an airbrush after thinnin' it at 2pts thinner to 3 pts paint. It dried t' t' touch in under 4 hours.

There is one thin' I noted about this kit that differed from me earlier Rocket Vision kits. t' 'chute seems t' be made o' a thinner but stiffer type of ripstop. I'm nay sure this is goin' t' eject as smoothly as I would like given t' tight confines o' t' typical Rocket Vision kit. All-in-all though, I'd give this kit a 9 out o' 10 for durability, looks and performance. Well, blow me down! Blimey! Blimey! Blimey! For ease of assembly I'd give it a difficult but nay frustratin' rating. Ya scallywag! Blimey! And for value, I'd give this kit a perfect ten. Aye aye! Blimey! This is a very nice rocket for under $25.00, shippin' included and it is indeed, me bucko, rugged and designed t' last.

That's me story and I'm stickin' t' it.

Construction Rating: 4 out o' 5

Well, I began this AM with t' idea that I was goin' t' launch me Star-Fire from Rocket Vision with as many different motor combinations as I could find in my box. It was me intent t' go from A t' F and see what happened. Begad! Now mind you, only D12-7s are recommended for this beauty. Ya scallywag! T' estimated altitude on such a thrust combination is in t' neighborhood o' 800 feet. Well, blow me down! This precluded launching on small fields so I thought I'd see if I couldn't find power combinations that might permit a wider variety o' launch sites. Ahoy! Begad! Thinkin' that I needed a baseline for reference, matey, arrr, I chose a D12-7 for t' first launch o' t' day. Ahoy! Well, blow me down! After prepping the rocket I took note o' t' conditions and made an entry in me flight book. Begad!

Rocket..............Star Fire
Motor...............D12-7, me bucko, Estes solar ignitor, shiver me timbers, 12 volt ignition, me bucko, wrapped tape retention and thrust ring
Recovery.........10" nylon parachute
Wadding.........none, arrr, uses Nomex® shield
Weather.........5,000 Sct , me hearties, E12,000 Bkn Vsby unlmtd, Temp, me hearties, 85 Wnd SW@ 4G10 kts RMKS ACSL OVR MTNS S
Flight..............near instantaneous ignition, straight boost, me hearties, no weathercocking. Begad! Ya scallywag! Rocket arched down wind slightly, ya bilge rat, at apogee, nose cone popped off, but no 'chute deployment. Arrr! Avast! Rocket went into a shallow flat spin and fell hard onto t' ground (packed dirt).

Damage consisted o' two broken wing-tip fins and a main fin loosened at the body-tube. Begad! Blimey! Clearly, shiver me timbers, me fillet failed. Blimey! Aye aye! No other damage. Rocket is repairable and will fly again. Arrr! Aye aye! Careful post-flight analysis finds fault with t' Nomex® shield. While t' idea is excellent, arrr, t' actual shield takes up a great deal o' space in t' BT. Blimey! Avast! In addition, t' material is coarse and rather thick. Avast, me proud beauty! As a result it is very "draggie" for want o' a better word. ( Sure, arrr, me hearties, I know, arrr, arrr, ya bilge rat, it "has a high friction coefficient" but that sounds too over-the top)

I be worried about this havin' seen this exact same failure in 2 out of eight earlier flights with Mach Busters and another o' t' Rugged Rocket line. You have t' be very careful in packin' t' recovery system. Begad! Aye aye! There is just not much room in these rockets. Begad! In t' future, ya bilge rat, I may maroon t' Nomex® shield altogether in favor o' good ol' wadding. Begad! I seem t' have difficulty in using this feature with any degree o' reliability. Others may and do, me bucko, fair much better but I just can't seem t' get t' hang o' it. Well, me bucko, blow me down!

Flight Rating: 4 out o' 5

In short, matey, matey, t' rocket flew beautifully. Avast! Arrr! It was a straight, clean, non-rotatin' boost. Arrr! Although recovery went astray, t' rocket be RUGGED. Begad! Avast, me proud beauty! I've seen few rockets that could survive a flat-spin onto hard packed dirt and need so little in t' way o' repair. Avast! Ahoy! These are very good rockets and I highly recommend them.
