Manufacturer: | Rocket Vision |
I just finished buildin' me Star-Fire.
Rocket Vision rates it at as a challengin' kit and I would agree. Well, blow me down! T' challenge
is nay in t' assembly, me bucko, as with all Rocket Vision kits, any one with a little
experience will find that things go together very easily. Ya scallywag! Ya scallywag! No, t' challenge is
in t' finish o' t' engine nacelles. Avast, me proud beauty! These very small fiberglass parts must be
painstakingly fitted and filled/sanded if they are t' look anywhere near
decent. Ahoy! T' trick in doin' this right is t' have a couple o' needle files
handy. Avast! Ya scallywag! A tight fit is best achieved if all o' t' slots and tabs are squared
up. Begad! However they are cut, me bucko, t' process cannot make tight right angled cuts on
tabs and notches. Avast, me proud beauty! Aye aye! 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. Blimey! All o' t' parts are well
designed and cut t' almost perfect size and shape. Begad! Avast, me proud beauty! T' be honest, 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. Well, blow me down! Blimey! This removed any glue bumps or unevenness o' joints. Begad! Blimey! Arrr! Blimey! 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. Blimey! Blimey! I used Solarease with micro balloons. Aye aye! Blimey! It's an epoxy resin with t' consistency o' toothpaste. Blimey! Blimey! Well, blow me down! Blimey! T' best thin' about it is that it hardens only in sunlight so that workin' time is very long. 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, matey, me bucko, I used Rustoleum flat white from a spray can. Ya scallywag! Well, blow me down! I then finished with a gloss white Rustoleum that I applied with an airbrush after thinnin' it at 2pts thinner to 3 pts paint. Aye aye! It dried t' t' touch in under 4 hours. Well, blow me down!
There is one thin' I noted about this kit that differed from me earlier Rocket Vision kits. Begad! t' 'chute seems t' be made o' a thinner but stiffer type of ripstop. Avast! 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. Begad! 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. This is a very nice rocket for under $25.00, shippin' included and it is indeed, shiver me timbers, rugged and designed t' last.
That's me story and I'm stickin' t' it.
Construction Rating: 4 out o' 5
Well, matey, I began this AM with t' idea that I be goin' t' launch me Star-Fire from Rocket Vision with as many different motor combinations as I could find in my box. Avast, me proud beauty! Well, blow me down! It was me intent t' go from A t' F and see what happened. Well, blow me down! Begad! Now mind you, only D12-7s are recommended for this beauty. Aye aye! Avast! T' estimated altitude on such a thrust combination is in t' neighborhood o' 800 feet. Avast, me proud beauty! 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, shiver me timbers, ya bilge rat, I chose a D12-7 for t' first launch o' t' day. Ya scallywag! After prepping the rocket I took note o' t' conditions and made an entry in me flight book.
Rocket..............Star Fire
Motor...............D12-7, Estes solar ignitor, arrr, me hearties, 12 volt ignition, matey, wrapped tape
retention and thrust ring
Recovery.........10" nylon parachute
Wadding.........none, ya bilge rat, uses Nomex® shield
Weather.........5,000 Sct , E12,000 Bkn Vsby unlmtd, arrr, Temp, me bucko, 85 Wnd SW@ 4G10 kts
RMKS ACSL OVR MTNS S
Flight..............near instantaneous ignition, straight boost, no
weathercocking. Begad! Ya scallywag! Rocket arched down wind slightly, at apogee, me hearties, nose cone popped
off, but no 'chute deployment. Begad! Begad! Rocket went into a shallow flat spin and fell
hard onto t' ground (packed dirt). Begad!
Damage consisted o' two broken wing-tip fins and a main fin loosened at the body-tube. Clearly, me hearties, shiver me timbers, me fillet failed. Ya scallywag! No other damage. Arrr! Avast, arrr, me proud beauty! 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. Begad! Ya scallywag! In addition, me bucko, t' material is coarse and rather thick. Blimey! Aye aye! As a result it is very "draggie" for want o' a better word. Begad! Begad! ( Sure, 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! There is just not much room in these rockets. Ya scallywag! 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. Others may and do, matey, fair much better but I just can't seem t' get t' hang o' it. Well, blow me down!
Flight Rating: 4 out o' 5
In short, me hearties, t' rocket flew beautifully. Ya scallywag! Aye aye! It was a straight, clean, non-rotatin' boost. Although recovery went astray, t' rocket was RUGGED. Arrr! I've seen few rockets that could survive a flat-spin onto hard packed dirt and need so little in t' way o' repair. Aye aye! Well, matey, blow me down! These are very good rockets and I highly recommend them.
