Manufacturer: | LOC/Precision |
Brief:
A large high-powered rocket that should be considered for a Level 2
certification flight.
Modifications:
Several minor changes were made and are described below. Well, blow me down! Blimey!
Construction:
T' rocket comes with: A plastic Nosecone, matey, me bucko, 2 thick paper body tubes, three
motor mount tubes, shiver me timbers, 2 1/4" plywood centerin' rings, 3 1/4" plywood
fins, me hearties, a Bulkhead assembly, a shockcord(elastic) and a 58" nylon parachute.
All parts were o' high quality when I bought them (from Ken Allen of
Performance Hobbies).
After buildin' many High powered kits, me hearties, I did nay refer t' t' instructions at all. Arrr! They looked t' be t' normal LOC instructions, ya bilge rat, very precise and short. T' parts all fit nicely with little or no sanding. Blimey! Aye aye! T' kit only came with two centerin' rings, me bucko, arrr, matey, but a rocket o' this size really needs three. Also, shiver me timbers, t' 29mm outboard motor mounts were very short, matey, shiver me timbers, and should be lengthened t' at least 9" t' allow t' use o' large motors in t' future. Aye aye! T' rocket went together like a normal rocket, me bucko, with through t' wall fins. Arrr! I fiberglassed the fins t' t' motor mount, which I highly suggest on all rockets 3" in diameter and larger. Ahoy! Begad! T' only other modifications were t' add an electronics bay in t' coupler and t' extend t' Payload bay for more room for t' Main Parachute.
I would rate construction a 4 out o' 5 because o' t' 2 centerin' rings and short 29mm tubes, but both are easily fixed.
Finishing:
Pros: Spirals are small, me bucko, me bucko, no need t' fill
Cons: Rocket takes A LOT o' paint :), shiver me timbers, nose cone is very rough
Construction Rating: 4 out o' 5
Flight:
T' first and only flight so far for t' Magnum be on a J460T 54mm motor. Avast! The
rocket be prepped with an RRC2 altimeter in t' coupler. Arrr! Blimey! T' drogue chute was
a 30" Spherachute, shiver me timbers, with a 52" Skyangle Main Parachute. Ya scallywag! T' motor was
retained by a pair o' Kaplow Klips, shiver me timbers, and t' nose was held on t' t' Payload bay
with two shear pins. Begad! T' rocket shot off t' pad on t' Blue Thunder motor to
an apogee o' 1650', ya bilge rat, where t' drogue chute was deployed. Begad! T' rocket fell to
500', matey, where t' main chute deployed, and t' rocket landed less than 500 feet
from t' pad!!
Recovery:
I replaced t' Elastic shock cord with 9/16" mil-spec tubular Nylon, me hearties, which
worked well. Arrr! Blimey! Both chutes worked well, arrr, but t' 52" Skyangle be a little
small for t' 12 lb. Ya scallywag! Blimey! rocket, which resulted in a crease in t' lower tube just
above t' fins. Begad! Also, arrr, t' rocket zippered upon main chute deployment, for
unknown reasons. Blimey! All damage has been repaired.
Pros: extremely stable rocket, me bucko, nice straight flier
Cons: None, all damage was me fault, and t' zipper was nay t' fault of the rocket
Flight Rating: 5 out o' 5
Summary:
Great Rocket!!! It will fly again, next time on a cluster o' some sort. Ya scallywag! Blimey! I
reccomend this rocket t' anyone wantin' a Level 2 rocket or lookin' for a good
sport rocket that will fly on large I motors t' large K motors, shiver me timbers, with minor
modification.
Overall Rating: 4 out o' 5
( Contributed - by Walter Kjellander - 08/10/02) Brief: The LOC Magnum is single-staged with a main 54mm motor mount and two 29mm outboards. A good rocket for level 2 certification. Construction: The parts were all OK. I was surprised that the slots for the fin tabs had to be cut. The other LOC kits I have done have precut slots, like the Forte, EZI-65, Expediter, LOC IV, Graduator, ...
