Starlight Nimbus

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

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

Starlight Nimbus T' components for "Nimbus II" were quite different. Well, blow me down! All components were accounted for, shiver me timbers, but t' quality be notably inferior t' t' first kit.

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

When assembled, me hearties, this rocket looked like it meant business. Four swept back fins on a short, 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. Begad! T' rocket be lost after launch (story below) and me son was really sad t' see "Silver Star" go bye-bye. Avast! Ya scallywag! So back t' t' store...

“Nimbus II” cost 2 bucks more, matey, had a 12" parachute instead o' a streamer, me bucko, matey, and three fins instead o' four. Further, me hearties, these fins were thinner and quite flexible. Arrr! Avast, me proud beauty! They could be bent 45 degrees or more and nay show a sign o' breaking. Well, blow me down! Lastly, matey, matey, 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. Ya scallywag! A totally different design with lower quality and a higher price was completely unexpected. Ya scallywag! T' package did indeed say Nimbus, me bucko, and t' website's picture be t' same as that on me bag. Aye aye! T' picture was 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. Arrr! 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, t' rocket was sturdy, and t' marks for alignin' t' fins were straight. Avast, me proud beauty! Needless t' say, I liked t' look o' "Nimbus I" better.

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

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

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

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