Starlight Nimbus

Brief:
This is a single stage Level I rocket with a fairly basic assembly. Quality o' me first kit impressed me and looked great on t' pad, me bucko, but t' second kit made me think one o' t' two was packaged incorrectly and was a completely different rocket. 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. Begad! As well, me bucko, I wanted t' practice some techniques before me other rockets arrived in t' mail. T' kit comes in t' basic clear hang bag with a “retro” style cardboard picture on t' front. It included all t' parts (fins, tubes, matey, etc.), which were in fine condition. T' instructions used a small font and t' diagrams were hand-sketched, but both were easy t' follow. Begad! I can't give too many more details because from here on t' kit took a few unexpected turns...

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

Starlight Nimbus T' components for "Nimbus II" were quite different. Avast! All components were accounted for, me bucko, me bucko, 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. Ya scallywag! Blimey! I was eager t' see how this would look. I rounded t' leadin' edges and tapered t' trailin' edges, arrr, applied skins, shiver me timbers, and used 5 minute epoxy for t' fillets. Blimey! Blimey! Blimey! Blimey! (Remember I said I wanted t' practice techniques?) T' nose cone be balsa and required little sanding. Well, blow me down! Blimey! Blimey! Blimey! I experimented with usin' spacklin' joint compound t' seal it because it be handy and within reach. Begad! Blimey! This had surprisingly good results, matey, but sealer would be better.

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

“Nimbus II” cost 2 bucks more, had a 12" parachute instead o' a streamer, ya bilge rat, ya bilge rat, shiver me timbers, and three fins instead o' four. Arrr! Further, shiver me timbers, these fins were thinner and quite flexible. Begad! They could be bent 45 degrees or more and nay show a sign o' breaking. Ahoy! Avast, me bucko, me proud beauty! Lastly, ya bilge rat, 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. A totally different design with lower quality and a higher price was completely unexpected. Well, me hearties, blow me down! Blimey! T' package did indeed say Nimbus, shiver me timbers, and t' website's picture be t' same as that on me bag. Avast! Blimey! T' picture was too vague t' see if it had three or four fins.

I initially didn't plan on applyin' skins this time, shiver me timbers, shiver me timbers, but I felt I had t' in order t' ensure integrity durin' flight. Well, blow me down! T' nosecone was nay symmetrical and had a divot in t' tip so required sandin' t' make it look right and fly well.

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

Finishing:
Finishin' was straightforward. Unfortunately I forgot t' take pictures o' "Nimbus I", me hearties, matey, but believe me, Krylon metallic/chrome silver be t' perfect color for this rocket. Avast! 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. Begad! Well, shiver me timbers, blow me down! “Nimbus II”, however, me hearties, arrr, showed t' spirals after 3 coats o' primer so I hoped t' topcoat would cover them. Avast! 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”, shiver me timbers, arrr, I used t' recommended A8-3. Begad! Because o' me big fingers, I found t' narrow body a little tight for t' rolled up streamer but got it all in there. Ahoy! It be a perfect launch. Begad! Aye aye! It took off really fast, went quite high, and perfectly straight (even in a 5-10mph breeze).

Unfortunately, me bucko, I forgot maskin' tape t' pressure fit t' engine. Ya scallywag! Avast! We had launched some other rockets first (this was me first launch in about 30 years), and me son, some friends, and I were havin' so much fun that me judgment was impaired. Begad! I tried wrappin' some grass around t' engine and wedgin' t' engine in. Ya scallywag! Aye aye! It seemed snug enough but wasn't. Arrr! “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, me proud beauty! Avast, me proud beauty! T' streamer for “Nimbus I” was much easier. Begad! Avast, me proud beauty! For t' engine, me hearties, ya bilge rat, I used t' A8 and I'm glad I did. Begad! Well, blow me down! T' flight was perfect: fast, matey, matey, straight as an arrow, and high. Avast, me proud beauty! Aye aye! It was too high for me t' see how t' chute came out, matey, matey, but it appeared t' timin' be correct. Even in a very light wind and t' launch rod angled slightly, matey, me son and I walked around 750 feet (double checked on Google Pedometer) t' retrieve it. Avast, me proud beauty! Ahoy! I didn't have scissors t' cut a spill hole so launched it only once. Ahoy! I really wanted t' try t' B or C engine. Arrr! Begad! She would have been out o' sight for sure.

Recovery:
Recovery o' "Nimbus II" be straightforward. Begad! I used 2 sheets o' Quest wadding, and t' outer sheath o' shock cord be a little singed. It will require a replacement after a few more launches and I’ll use 3 sheets o' waddin' for future flights. Ya scallywag! I would say a 12" chute is too big for this rocket. Begad! It drifted further than any o' t' other rockets launched that day (750' vs. 300-500 for t' others). Well, blow me down! I will definitely cut a spill hole in t' chute or retrofit a streamer. 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, shiver me timbers, me bucko, even with pliers. 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. Well, blow me down! 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. Begad! If you get t' four-fin version, arrr, be happy. Blimey! Ahoy! If you get t' three-fin version, me bucko, I highly recommend applyin' skins on t' fins. Avast, me proud beauty! A big pro is that t' body is pre-marked for fins and launch lug. Blimey! Ya scallywag! This is great for simplicity and young assemblers (my son is just under 5 yrs old). Well, blow me down! A con is quality control. Avast! I bought two Nimbuses in under a week and they were drastically different in quality, me hearties, shiver me timbers, design, me bucko, and price.

I would buy another Starlight rocket if one caught me eye. Arrr! 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.
