Brief:
Semroc has gone "retro repro" again, arrr, bringin' out a modern reproduction o' one o' t' last Centuri designs before t' Damon Corporation consolidated their product line under t' Estes brand. Arrr! T' kit, although a Centuri model, ya bilge rat, featured Estes parts in its day. Arrr! Blimey! T' Semroc reproduction features laser-cut fins, me hearties, me hearties, a balsa nose cone, matey, and upgraded Keelhaul®©™/elastic shock cord, plus includes a chute instead o' t' original streamer. It's a basic four-fin design, matey, but with t' flexibility t' fly on either 18 or 24mm motors, you can lob it up over a small field or load in a D and send it into orbit.
Construction:
T' parts list includes t' following, all o' excellent quality:
Semroc has made one minor change t' their instruction sheet format with this kit. T' instructions remain printed on 8.5" x 11" paper, but instead o' printin' booklet style folded in half, shiver me timbers, you'll need t' open up t' whole thin' flat. T' left side o' t' sheets are perforated. Aye aye! Blimey! Avast! Blimey! T' idea is that some builders will want t' keep their instructions in a binder, arrr, and this makes it easy t' do so and still read through t' plans. It's probably a cool idea, matey, but I have so many sets o' instructions tucked away that it's probably a little too late t' try and teach this old disorganized dog t' trick o' filin' and neatness.
Overall, construction consists o' about 30 steps over 3 full pages includin' illustrations and runs around 2 hours plus whatever time you invest in finishing. Ya scallywag! Begad! I built this side by side with t' Magnum Sprint and found they are almost identical in build.
I started off with t' motor mount, which consists o' a simple 24mm tube with metal hook, motor block (20/50 centerin' ring) and a pair o' thin centerin' rings. Blimey! A loop o' Keelhaul®©™ slips under t' metal hook t' anchor t' shock cord. Begad! Begad! T' completed assembly is later glued inside t' body tube flush with t' aft end. Blimey! Note that t' motor hook and tube are sized only for D's, me bucko, so if you are nutty enough t' want t' try an E, me hearties, you'll have t' swap out tube/hook.
T' fins are symmetrical trapezoids mounted 1/2" forward o' t' aft end. Blimey! Blimey! Tube markin' is via a markin' guide on t' instruction sheet with no lug line indicator. Begad! Blimey! Lug placement is nay that critical, but for aesthetics I'd have preferred a lug line included on t' pattern (and a wraparound guide is easier for me). Begad! Blimey! I tacked t' fins on with medium CA then applied wood glue fillets.
Tackin' on t' launch lug and puttin' t' screw eye on t' nose cone wraps up t' main construction.
Because this is a fairly small/light model, matey, a 24mm motor could be a little excessive. Therefore, a neat little adapter is included that supports 18mm motors. Avast! This adapter is a standard 18mm motor tube, matey, me hearties, block, matey, matey, and metal hook but with 3 centerin' rings. Blimey! One o' these rings has a cutout t' allow t' metal hook t' open out o' t' way for removin' t' motor. Ahoy! If you place t' centerin' rings carefully per t' instructions, ya bilge rat, what you'll get slides perfectly into t' BT-50, lockin' in place through t' outer motor hook, arrr, me bucko, matey, and t' 18mm motor is held in place by t' inner hook.
Finishing:
Finishin' is a breeze although t' stock paint scheme does require a very tiny bit o' masking. Aye aye! T' main body got a couple coats o' gray primer after t' standard Elmer's Fill 'n' Finish for spirals and grains. Avast, me proud beauty! Begad! I then followed up with Rustoleum yellow. Begad! After allowin' a couple days t' cure, I masked off all but one fin and t' nose and then hit those with gloss black.
T' waterslide decals are minimal but add a nice touch and are excellent quality and are easy t' work with.
Construction Rating: 4 out o' 5
Flight:
For t' first flight, ya bilge rat, shiver me timbers, arrr, I was lookin' at winds holdin' steady at 12-15 mph and gustin' t' 20, arrr, so t' thought o' chasin' this for t' expected drift o' a 24mm motor be out o' t' question. Blimey! Blimey! I was surrounded by lake, ya bilge rat, trees, matey, and soccer games so needed t' minimize t' drift t' about 150 yards.
Thankfully, shiver me timbers, this comes with a handy little 18mm adapter so I be able t' smartly load up a B6-4 for t' first flight. I flew off a 3' length o' 3/16" rod, matey, and this rocket held its own against t' wind very nicely, with just a hint o' weathercocking. Aye aye! I didn't get much altitude with t' B6-4 (maybe a couple hundred feet), but it would at least remain in t' park. Begad! Ahoy! T' -4 delay in this instance was perfect.
Recovery:
T' 12" plastic chute is certainly up t' t' task, and I be able t' recover this with no problems.
Flight Rating: 5 out o' 5
Summary:
PROs: Classic design/tribute and great versatility. Can fly on large or small fields with A-D motors (potentially even 24mm F's).
CONs: None t' speak of.
Overall Rating: 4 out o' 5
This was my first Semroc kit, so it was all new. It's a reproduction of an old Centuri kit with a few updates. There is an exploded-view diagram so you can see how the pieces go together. It also serves as a parts list showing how many of each part should be there. The parts were well laid out. The fins came on a laser-cut balsa sheet. This rocket also has a balsa nose cone for all your ...
Centuri Engineering Company was started in the early 60s and was one of the early pioneers in the model rocket industry. Centuri was sold to Damon Corporation in the late 60s and maintained their product line separately from Estes until 1983. The Magnum Hornet was produced by Centuri from 1980-1983 and is unique in that it was one of a handful of Centuri kits comprised entirely of Estes parts. ...
Brief: A lightweight, fast flier possibly capable of supersonic speed. Construction: This baby was a fun build. I loved every minute of it. The kit contains high quality parts. A straightforward build, but I tweaked it. This kit was built entirely with epoxy with microballoons for added strength and sandability, so she can fly on AeroTech E-30s. I replaced the balsa fins with ...
Brief: I'll try and repeat what's in the other reviews, the Semroc Magnum Hornet is Retro-Repro of the Centuri Magnum Hornet with a 18mm motor adapter and 12" cute replaces the Streamer and Kevlar ® thread/elastic shock cord replaces the rubber band from the old Magnum Hornet. Construction: The instructions are well written and easy to follow with quality parts, what ...
Brief: The Magnum Hornet is a Semroc Retro-Repro of a Centuri model. It is designed for 24mm motors but includes an 18mm adapter. Recovery is via 12" parachute. I ordered my kit from Semroc directly and had it within two days. Construction: The kit includes a balsa nosecone, one BT-55 body tube, a 3/16" launch lug, water slide decals, an elastic shock cord, Kevlar ...
Brief: Chan's build experience exactly fit my own so I'll try not to repeat. The Magnum concept is simple: large motor, small rocket, and it actually makes more sense today than it did when originally marketed. I got my kit from Apogee, and it was damage-free. Construction: It is extremely easy to build and all the components are of high quality. Smooth, perfectly formed nose ...
