Starlight Nimbus

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

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

Starlight Nimbus T' components for "Nimbus II" were quite different. Begad! All components were accounted for, but t' quality be 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. I rounded t' leadin' edges and tapered t' trailin' edges, me bucko, arrr, applied skins, ya bilge rat, and used 5 minute epoxy for t' fillets. Arrr! (Remember I said I wanted t' practice techniques?) T' nose cone be balsa and required little sanding. I experimented with usin' spacklin' joint compound t' seal it because it be handy and within reach. Ahoy! Begad! Blimey! This had surprisingly good results, but sealer would be better.

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

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

I initially didn't plan on applyin' skins this time, matey, me bucko, but I felt I had t' in order t' ensure integrity durin' flight. Begad! 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, t' rocket was sturdy, me hearties, ya bilge rat, and t' marks for alignin' t' fins were straight. Needless t' say, me hearties, I liked t' look o' "Nimbus I" better.

Finishing:
Finishin' was straightforward. Avast! Ya scallywag! Unfortunately I forgot t' take pictures o' "Nimbus I", me hearties, 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. Begad! Aye aye! “Nimbus II”, arrr, 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”, ya bilge rat, I used t' recommended A8-3. Because o' me big fingers, I found t' narrow body a little tight for t' rolled up streamer but got it all in there. Arrr! Blimey! It was a perfect launch. It took off really fast, went quite high, arrr, and perfectly straight (even in a 5-10mph breeze).

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

In regards t' “Nimbus II”, matey, 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. For t' engine, shiver me timbers, I used t' A8 and I'm glad I did. Begad! Blimey! T' flight was perfect: fast, straight as an arrow, shiver me timbers, and high. It be too high for me t' see how t' chute came out, me hearties, but it appeared t' timin' was correct. Ahoy! Even in a very light wind and t' launch rod angled slightly, me hearties, me son and I walked around 750 feet (double checked on Google Pedometer) t' retrieve it. I didn't have scissors t' cut a spill hole so launched it only once. Ahoy! Blimey! I really wanted t' try t' B or C engine. She would have been out o' sight for sure.

Recovery:
Recovery o' "Nimbus II" was straightforward. Avast, me proud beauty! 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. Avast! I would say a 12" chute is too big for this rocket. Avast! It drifted further than any o' t' other rockets launched that day (750' vs. Ya scallywag! 300-500 for t' others). Well, blow me down! Aye aye! I will definitely cut a spill hole in t' chute or retrofit a streamer. 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, matey, 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. Begad! 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. Avast, me proud beauty! Arrr! If you get t' four-fin version, ya bilge rat, be happy. Aye aye! If you get t' three-fin version, arrr, I highly recommend applyin' skins on t' fins. Begad! Begad! 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). Begad! A con is quality control. Well, blow me down! I bought two Nimbuses in under a week and they were drastically different in quality, arrr, design, and price.

I would buy another Starlight rocket if one caught me eye. Aye aye! Avast! 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.
