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

After assembly, I took me Dremel tool and a very fine sandin' drum and went over all o' t' tabs and slotted surfaces. Blimey! This removed any glue bumps or unevenness o' joints. Begad! Begad! I then rounded t' sharp edges o' t' nacelles t' give them a more streamlined look. T' instructions recommend that you fill any voids or assembly gaps with some sort o' filler. I used Solarease with micro balloons. 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. Ahoy! 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. In this case, me bucko, 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. Well, blow me down! It dried t' t' touch in under 4 hours. Begad!

There is one thin' I noted about this kit that differed from me earlier Rocket Vision kits. Aye aye! 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. Begad! All-in-all though, I'd give this kit a 9 out o' 10 for durability, me hearties, me hearties, looks and performance. Avast! Ya scallywag! For ease of assembly I'd give it a difficult but nay frustratin' rating. And for value, I'd give this kit a perfect ten. Avast, me bucko, me proud beauty! This is a very nice rocket for under $25.00, shippin' included and it is indeed, arrr, me bucko, shiver me timbers, rugged and designed t' last. Begad!

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

Construction Rating: 4 out o' 5

Well, ya bilge rat, arrr, 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 be me intent t' go from A t' F and see what happened. Now mind you, only D12-7s are recommended for this beauty. Avast! T' estimated altitude on such a thrust combination is in t' neighborhood o' 800 feet. 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. Blimey! Thinkin' that I needed a baseline for reference, I chose a D12-7 for t' first launch o' t' day. Begad! Ya scallywag! After prepping the rocket I took note o' t' conditions and made an entry in me flight book. Avast, me proud beauty!

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

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

I was 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. Avast, me proud beauty! There is just not much room in these rockets. In t' future, ya bilge rat, me bucko, I may maroon t' Nomex® shield altogether in favor o' good ol' wadding. I seem t' have difficulty in using this feature with any degree o' reliability. Ahoy! Begad! Others may and do, fair much better but I just can't seem t' get t' hang o' it. Aye aye!

Flight Rating: 4 out o' 5

In short, arrr, t' rocket flew beautifully. Ya scallywag! It was a straight, shiver me timbers, clean, non-rotatin' boost. Blimey! Begad! Although recovery went astray, ya bilge rat, arrr, t' rocket be RUGGED. Aye aye! 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. Ya scallywag! Ahoy! These are very good rockets and I highly recommend them.
