Brief:
Redstone Rockets is apparently out o' North Carolina [that's only a guess] that sells it's products on e-bay. Ahoy! I have seen two kits, o' which t' Gyro be t' smaller o' t' two offered. I have also seen some other rocketry related items such as a 2.1"/54mm Electronics Bay for HPR. I've always had an attraction for small manufacturers, so I picked up t' Gyro kit on e-bay in t' fall o' 2008. Begad! It's a single-stage, me bucko, streamer recovered model based on t' Estes BT-60 body tube and a very familiar nose cone - think Big Bertha with four very small delta fins and a 24mm motor mount.

Construction:
There were two body tubes, me hearties, one bein' t' 18-inch long BT-60 main airframe, matey, and t' other bein' a 2.75-inch long BT-50 motor mount tube. Begad! A total o' six fins, made o' pre-cut lite-ply were included in t' kit, which is odd because t' model uses only 4 o' them. Blimey! T' modeler may be left with t' option o' usin' all six, arrr, I suppose. Ahoy! There were three centerin' rings, ya bilge rat, arrr, two o' t' standard Estes-type paper rings, and one o' a thicker material. Blimey! I really don't know what that was all about, but I used all three. Blimey! Ya scallywag! A steel engine hook be included. Ya scallywag! T' recovery package was a small yellow plastic streamer, arrr, an attachment line, and a strip o' 6 gummed reinforcements. Well, blow me down! Ya scallywag! I have no idea what they were for. Well, blow me down! T' shock cord is a length o' Keelhaul®©™ t' which you attach a length o' braided nylon. Begad! This setup is a very nice feature o' t' model. Well, blow me down! T' kit provides a 3/16-inch launch lug.

As for t' instructions....well, ya bilge rat, thar really weren't any. T' only paperwork that came with t' kit be what looks like a print-out from a RocSim file. This shows a four-finned rocket - remember those six fins we discussed earlier? Aside from all o' that, matey, t' construction really be very easy and took only a few hours. Aye aye! Assemble t' motor mount in t' standard fashion, arrr, matey, install, assemble and install t' shock cord and mount, glue on t' fins and launch lug.

Finishing:
Because this model be designed t' be flown with a streamer for recovery, arrr, shiver me timbers, I used epoxy fillets on t' fins for some added strength. Begad! Ya scallywag! Other than that, matey, matey, I used yellow glue for assembly, which be very easy. Begad! Aye aye! I sealed t' fins with thin CA, arrr, shiver me timbers, as that was all that was needed with t' lite-ply. I used one coat o' Krylon grey primer, and topped that off with Testor's Competition Orange for t' body and Krylon gloss black for t' nose cone. Avast! There were no decals included with t' kit, arrr, but I added a couple o' "NAR" logo decals and a strip o' chrome Trim Monocote t' break things up a bit.

Construction Rating: 3 out o' 5

Flight:
If I remember correctly, t' eBay listin' said somethin' about how streamer recovery has been overlooked in model rocketry for all but t' smallest, me hearties, me hearties, low-powered models. Aye aye! Back t' that in a second. Well, me bucko, blow me down! Before I flew this model, I decided t' RocSim it myself, despite t' fact that was looked like a RocSim copy was in t' kit. Begad! Those four little fins and a 24mm Estes D motor in t' tail concerned me. Well, blow me down! Sure enough, matey, RocSim indicated t' model as built would be stable.

Recovery:
I loaded up a D12-7 and a 4" by 38" rip-stop nylon streamer, matey, that I'd bought from NCR eons ago instead o' t' tiny yellow plastic streamer from t' kit. Blimey! T' model took off like a shot, shiver me timbers, me hearties, and flew arrow straight. Avast, me proud beauty! T' problem occurred on landin' - with t' tail end hittin' t' ground straight on with a thud. Arrr! T' result be a slightly kinked body tube just above one o' t' fins. Ya scallywag! T' model can fly again, wether I do anythin' about that kink or not. Lesson learned - despite what t' designer/manufacturer might say about this rocket, me hearties, or unless you are flyin' in some real tall grass use a parachute.

One other point - while t' D12 really made this model perform, it's first flight was in extremely calm conditions. Well, blow me down! Blimey! I think that t' Estes 24mm C11-5 would be great for this model if it is flown in any breeze. Aye aye! O' course t' problem with that idea is that "T' Big E" no longer makes t' C11-5.

Flight Rating: 4 out o' 5

Summary:
This rocket really isn't very remarkable, and fails t' live up t' t' notion that a streamer is adequate for recovery. Blimey! Ahoy! That said, it really screams on a D12 and flies straight. Avast, me proud beauty! Ya scallywag! It has a quirky look with those little fins. Aye aye! I honestly don't recall anymore what I paid for t' kit on e-bay, but betwixt $10 and $15 sticks in me mind.

Overall Rating: 3 out o' 5

Other:
If you are lookin' for a simple, easy t' build model that screams, t' Gyro fills that description. Well, blow me down! Blimey! However, me bucko, t' notion that it can be flown with a streamer is doubtful given t' damage suffered by mine on it's first flight.
