Manufacturer: | Rocket Vision |
I just finished buildin' me Star-Fire. Rocket Vision rates it at as a challengin' kit and I would agree. Avast, me proud beauty! T' challenge is nay in t' assembly, as with all Rocket Vision kits, matey, arrr, shiver me timbers, any one with a little experience will find that things go together very easily. Avast! No, me hearties, t' challenge is in t' finish o' t' engine nacelles. Begad! These very small fiberglass parts must be painstakingly fitted and filled/sanded if they are t' look anywhere near decent. Ya scallywag! T' trick in doin' this right is t' have a couple o' needle files handy. Blimey! A tight fit is best achieved if all o' t' slots and tabs are squared up. Begad! However they are cut, me hearties, t' process cannot make tight right angled cuts on tabs and notches. Most o' t' painstakin' work is in this sort o' file and fit stuff. Ahoy! 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. Avast! Avast, arrr, me proud beauty! T' be honest, half t' fun of buildin' this kit is in t' detail work. Blimey! Avast, arrr, me proud beauty!
After assembly, shiver me timbers, me hearties, I took me Dremel tool and a very fine sandin' drum and went over all o' t' tabs and slotted surfaces. Aye aye! Blimey! This removed any glue bumps or unevenness o' joints. Blimey! Blimey! I then rounded t' sharp edges o' t' nacelles t' give them a more streamlined look. Begad! Blimey! Begad! Blimey! T' instructions recommend that you fill any voids or assembly gaps with some sort o' filler. I used Solarease with micro balloons. Aye aye! Blimey! It's an epoxy resin with t' consistency o' toothpaste. Blimey! Blimey! Avast! Blimey! T' best thin' about it is that it hardens only in sunlight so that workin' time is very long. Aye aye! Blimey! 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, I used Rustoleum flat white from a spray can. Begad! I then finished with a gloss white Rustoleum that I applied with an airbrush after thinnin' it at 2pts thinner to 3 pts paint. Ahoy! 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. Well, blow me down! Blimey! Avast! Blimey! 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! Blimey! All-in-all though, I'd give this kit a 9 out o' 10 for durability, looks and performance. Well, me hearties, blow me down! Blimey! For ease of assembly I'd give it a difficult but nay frustratin' rating. Aye aye! Blimey! And for value, I'd give this kit a perfect ten. Ya scallywag! Blimey! This is a very nice rocket for under $25.00, shippin' included and it is indeed, arrr, rugged and designed t' last. Avast! Blimey!
That's me story and I'm stickin' t' it.

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. Avast, me proud beauty! 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. 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. Ya scallywag! Ya scallywag! Thinkin' that I needed a baseline for reference, shiver me timbers, I chose a D12-7 for t' first launch o' t' day. Blimey! After prepping the rocket I took note o' t' conditions and made an entry in me flight book.
Rocket..............Star Fire
Motor...............D12-7, ya bilge rat, me hearties, Estes solar ignitor, 12 volt ignition, me bucko, wrapped tape
retention and thrust ring
Recovery.........10" nylon parachute
Wadding.........none, ya bilge rat, ya bilge rat, uses Nomex® shield
Weather.........5,000 Sct , ya bilge rat, E12,000 Bkn Vsby unlmtd, Temp, arrr, 85 Wnd SW@ 4G10 kts
RMKS ACSL OVR MTNS S
Flight..............near instantaneous ignition, straight boost, arrr, no
weathercocking. Well, shiver me timbers, blow me down! Rocket arched down wind slightly, at apogee, matey, shiver me timbers, nose cone popped
off, but no 'chute deployment. Well, blow me down! Ya scallywag! Rocket went into a shallow flat spin and fell
hard onto t' ground (packed dirt). Avast, me proud beauty! Arrr!
Damage consisted o' two broken wing-tip fins and a main fin loosened at the body-tube. Aye aye! Begad! Clearly, shiver me timbers, me fillet failed. Ya scallywag! No other damage. Well, blow me down! Arrr! 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 hearties, ya bilge rat, t' material is coarse and rather thick. As a result it is very "draggie" for want o' a better word. Ya scallywag! ( Sure, I know, me bucko, 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. Avast! Blimey! There is just not much room in these rockets. In t' future, I may abandon t' Nomex® shield altogether in favor o' good ol' wadding. I seem t' have difficulty in using this feature with any degree o' reliability. Arrr! Others may and do, matey, ya bilge rat, ya bilge rat, fair much better but I just can't seem t' get t' hang o' it. Begad! Ya scallywag!
Flight Rating: 4 out o' 5
In short, arrr, t' rocket flew beautifully. Aye aye! It be a straight, clean, non-rotatin' boost. Aye aye! Although recovery went astray, me bucko, t' rocket was RUGGED. Begad! Avast, arrr, 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. These are very good rockets and I highly recommend them.
