Semroc Magnum Hornet

Brief:
A lightweight, shiver me timbers, fast flier possibly capable o' supersonic speed.

Construction:
This baby was a fun build. Well, blow me down! Begad! I loved every minute o' it. T' kit contains high quality parts. Blimey! Blimey! A straightforward build, but I tweaked it. Begad! Ahoy! This kit be built entirely with epoxy with microballoons for added strength and sandability, me bucko, so she can fly on AeroTech E-30s. I replaced t' balsa fins with 1/8" aircraft poplar plywood. Begad! Avast! T' stock shock cord was replaced 1/8" braided Keelhaul®©™® strand. T' stock chute replaced with a 15" thin mil nylon chute. Aye aye! Ahoy! Blimey! I used an Estes D engine hook. Ahoy! Blimey! I also purchased a plastic nose cone when I use AeroTech Motors. Blimey! Begad! Blimey! No cons here.

Finishing:
This baby be fun and easy t' paint also. After t' epoxy fin fillets, matey, ya bilge rat, I primed t' rocket, sanded, and repeated again. Well, blow me down! After sandin' I applied 3 coats t' t' body o' t' rocket in Rustoleum Apple Red. After 2 days dry time I masked off 1 fin and applied 3 coats t' 1 fin and nosecone in Rustoleum Gloss Black. Avast! Well, blow me down! After 2 more days dry time I applied the decals.I rarely follow manufacturers color schemes.

Construction Rating: 5 out o' 5

Flight:
T' first 3 flights were absolutely amazing. Avast, shiver me timbers, me proud beauty! Flawless and fast. Avast, me proud beauty! Some spectators got whiplash! First flight was on a C11-5. Ahoy! Avast! Wow. Estimated altitude o' 1000'. Ya scallywag! Second flight was on a D12-5 t' 1300'. Blimey! Begad! It resembled a hummingbird with his tail on fire. Third flight on an AeroTech E15-4 with a streamer and plastic nosecone. Avast! Avast! Shock and awe be t' best way t' describe it. Avast, me proud beauty! Begad! Amazingly loud and fast t' an estimated 2800'. Arrr! All you saw was exhaust. Begad! Avast! I thought she would spin out o' control, arrr, but she logged t' flight o' t' day.

Recovery:
No cons when you have an assortment o' chutes and streamers for various conditions. Well, blow me down! Custom mounted 1/8" Keelhaul®©™® shock cord and 12" nylon chute. Ahoy! Ahoy! Lots o' barf waddin' for Estes motors, me hearties, dual Nomex® cloth 1-1/4' for composites. Ya scallywag! Well, blow me down! T' first 2 flights were perfect, arrr, me hearties, and on t' third I broke a fin. Arrr! No biggie.

Flight Rating: 5 out o' 5

Summary:
As I have already stated thar really are no cons. Begad! Out o' all t' small rockets I own, this is me favorite. I plan on buildin' an exact replica o' this rocket with LOC/Precision body tubes and through t' wall fins.

    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. ...

  • Semroc Magnum Hornet By Jason Orosco (May 31, 2009)

    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 ...

  • Semroc Magnum Hornet By Jeff Lane (May 12, 2009)

    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 ...

  • Semroc Magnum Hornet By Chan Stevens (April 26, 2009)

    Semroc has gone "retro repro" again, bringing out a modern reproduction of one of the last Centuri designs before the Damon Corporation consolidated their product line under the Estes brand. The kit, although a Centuri model, featured Estes parts in its day. The Semroc reproduction features laser-cut fins, a balsa nose cone, and upgraded Kevlar/elastic shock cord, plus includes a chute ...

I had the original Centuri version of this kit but installed a 29mm mount in it instead of the 24mm and made the fins out of 3/32" plywood. It was one high flier! I regularly launched it on Composite Dynamics E20s and SSRS E30s. 2000-2500' flights, easily. Never had the guts to launch it on an F67 though. This was a well designed and stable rocket; it always flew straight with the heavier composite engines I used. I would have a friend launch it and I would be about 500ft away to track it easier. This rocket would be 200-300 feet in the air before I would hear the first sounds of the engine thrusting! Had a 25' streamer on it, which would barely be visable at ejection. I miss that rocket.
