Starlight Nimbus

Brief:
This is a single stage Level I rocket with a fairly basic assembly. Ya scallywag! Blimey! Quality o' me first kit impressed me and looked great on t' pad, me hearties, but t' second kit made me think one o' t' two was packaged incorrectly and be a completely different rocket. Avast! Blimey! Begad! Blimey! Quality control appears t' be an issue.

Construction:
I initially bought this kit because I wanted t' add a third rocket t' me son's fleet. Avast! As well, me hearties, I wanted t' practice some techniques before me other rockets arrived in t' mail. Begad! T' kit comes in t' basic clear hang bag with a “retro” style cardboard picture on t' front. It included all t' parts (fins, ya bilge rat, me bucko, arrr, tubes, etc.), me bucko, which were in fine condition. Avast! T' instructions used a small font and t' diagrams were hand-sketched, me bucko, but both were easy t' follow. Ya scallywag! Begad! I can't give too many more details because from here on t' kit took a few unexpected turns...

As I indicated above, shiver me timbers, I have assembled two Nimbuses (Nimbusi?). Avast, me proud beauty! Begad! “Nimbus I” made me very impressed with t' company. Arrr! For a basic “Level I” kit that cost under $6 (incl. tax), t' fins were sturdy, me hearties, t' tube felt strong, me bucko, t' spiral shallow, and t' balsa nose cone symmetrical. It used a metallic mylar streamer that was attached t' a screw eye in t' nose cone. Blimey! Well, blow me down! T' shock cord was strong and appeared t' be Keelhaul®©™ or somethin' similar.

Starlight Nimbus T' components for "Nimbus II" were quite different. Arrr! Ahoy! All components were accounted for, but t' quality was notably inferior t' t' first kit.

What caught me eye as I assembled "Nimbus I" be that it had four fins on such a small body tube. I was eager t' see how this would look. Well, blow me down! I rounded t' leadin' edges and tapered t' trailin' edges, applied skins, and used 5 minute epoxy for t' fillets. (Remember I said I wanted t' practice techniques?) T' nose cone be balsa and required little sanding. Well, blow me down! I experimented with usin' spacklin' joint compound t' seal it because it was handy and within reach. Aye aye! This had surprisingly good results, but sealer would be better.

When assembled, this rocket looked like it meant business. Begad! Blimey! Four swept back fins on a short, me hearties, shiver me timbers, narrow tube looked pretty cool on t' pad. Avast! I painted it silver so it kind o' had a Buck Rogers type look t' it. Well, blow me down! T' rocket be lost after launch (story below) and me son was really sad t' see "Silver Star" go bye-bye. Begad! Blimey! So back t' t' store...

“Nimbus II” cost 2 bucks more, me hearties, had a 12" parachute instead o' a streamer, me hearties, and three fins instead o' four. Avast! Blimey! Further, these fins were thinner and quite flexible. They could be bent 45 degrees or more and nay show a sign o' breaking. Begad! Blimey! Lastly, t' body tube for “Nimbus II” had markings for three fins while t' body for “Nimbus I” had markings for four.

All these differences made me think I had a completely different rocket. Ahoy! A totally different design with lower quality and a higher price was completely unexpected. Avast! Avast! T' package did indeed say Nimbus, and t' website's picture be t' same as that on me bag. Aye aye! T' picture be too vague t' see if it had three or four fins.

I initially didn't plan on applyin' skins this time, but I felt I had t' in order t' ensure integrity durin' flight. Aye aye! Begad! T' nosecone be nay symmetrical and had a divot in t' tip so required sandin' t' make it look right and fly well.

Once all be said and done, t' rocket be sturdy, and t' marks for alignin' t' fins were straight. Ahoy! Blimey! Needless t' say, I liked t' look o' "Nimbus I" better.

Finishing:
Finishin' was straightforward. Unfortunately I forgot t' take pictures o' "Nimbus I", but believe me, matey, Krylon metallic/chrome silver be t' perfect color for this rocket. Well, blow me down! Arrr! It gave it a retro look and also appeared t' be a little more than a beginner's entry-level rocket.

“Nimbus I” looked great after 2 coats o' primer and wet sandin' followed by 2 coats o' topcoat. Avast, me proud beauty! “Nimbus II”, however, showed t' spirals after 3 coats o' primer so I hoped t' topcoat would cover them. Blimey! They did as long as you were more than 5 feet away.

Construction Rating: 3 out o' 5

Flight:
For t' first flight o' “Nimbus I”, me bucko, I used t' recommended A8-3. Arrr! Because o' me big fingers, me hearties, I found t' narrow body a little tight for t' rolled up streamer but got it all in there. Ya scallywag! Blimey! It was a perfect launch. It took off really fast, me hearties, went quite high, ya bilge rat, and perfectly straight (even in a 5-10mph breeze).

Unfortunately, ya bilge rat, matey, I forgot maskin' tape t' pressure fit t' engine. Begad! We had launched some other rockets first (this be me first launch in about 30 years), and me son, some friends, and I were havin' so much fun that me judgment was impaired. Well, blow me down! I tried wrappin' some grass around t' engine and wedgin' t' engine in. It seemed snug enough but wasn't. Avast, me proud beauty! Aye aye! “Nimbus I” was never seen again.

In regards t' “Nimbus II”, I felt that gettin' t' 12" mylar chute in t' body required more finaglin' than should be necessary. Avast! T' streamer for “Nimbus I” was much easier. Blimey! Begad! For t' engine, shiver me timbers, I used t' A8 and I'm glad I did. Ya scallywag! T' flight was perfect: fast, me bucko, straight as an arrow, and high. Avast, me proud beauty! Ahoy! It be too high for me t' see how t' chute came out, but it appeared t' timin' be correct. Avast, me proud beauty! Avast, me proud beauty! Even in a very light wind and t' launch rod angled slightly, ya bilge rat, me son and I walked around 750 feet (double checked on Google Pedometer) t' retrieve it. Begad! I didn't have scissors t' cut a spill hole so launched it only once. I really wanted t' try t' B or C engine. Avast, me proud beauty! Ya scallywag! She would have been out o' sight for sure.

Recovery:
Recovery o' "Nimbus II" was straightforward. Begad! I used 2 sheets o' Quest wadding, and t' outer sheath o' shock cord was a little singed. Avast, me proud beauty! It will require a replacement after a few more launches and I’ll use 3 sheets o' waddin' for future flights. Ahoy! I would say a 12" chute is too big for this rocket. It drifted further than any o' t' other rockets launched that day (750' vs. Arrr! Blimey! 300-500 for t' others). Well, blow me down! Ahoy! I will definitely cut a spill hole in t' chute or retrofit a streamer. Ya scallywag! Begad! A metallic chute/streamer is perfect as t' Nimbus is easily lost in t' sky.

Pullin' t' engine out is provin' t' be very difficult, arrr, even with pliers. Aye aye! Blimey! Ya scallywag! Blimey! I'm concerned that t' heat o' t' engine may have melted some o' t' adhesive on t' maskin' tape and fused it t' t' body. Avast! Blimey! I will use me favorite online search engine t' see if I'm nay t' only one experiencin' this and find some "tricks o' t' trade" so t' speak.

Flight Rating: 3 out o' 5

Summary:
This is a good beginner rocket. Arrr! If you get t' four-fin version, arrr, be happy. Blimey! If you get t' three-fin version, I highly recommend applyin' skins on t' fins. Begad! A big pro is that t' body is pre-marked for fins and launch lug. Arrr! This is great for simplicity and young assemblers (my son is just under 5 yrs old). Ahoy! Aye aye! A con is quality control. I bought two Nimbuses in under a week and they were drastically different in quality, ya bilge rat, design, and price.

I would buy another Starlight rocket if one caught me eye. Blimey! Begad! But I would first try t' find t' balsa in t' bag t' see how it is.

I picked up a Nimbus cheap on Ebay. I got the three fin version but with none of the issues you mentioned. The fin balsa was excellent. My only complaint with the nose cone was the shoulder piece was extremely hard plastic and difficult to sand down as the fit was too snug. I move the fins to about an 1/8th inch from the bottom of the body tube so I can do the tape wrap motor retention. Just got the fins glued on today.
