Brief:
This is a large single staged, simple mid/high power rocket. It uses parachute
recovery and was my first big rocket. Mine came with a 38mm motor mount,
although many websites say it has a 29mm motor mount. Also, the fin tabs extend
all the way to the motor tube.
Construction:
The components of this kit came in the typical LOC plastic bag. All of the
parts were of the highest quality. Get rid of the provided shock cord mount
though. A listing of the parts are:
The construction of this kit is similar to an Estes executioner or fat boy, or any other simple TTW (through the wall) kit. This is an excellent beginner's kit. It is big and simple to construct. The fins fit nice and snug into the slots and extend all the way to the motor tube. There are no cons about construction. Use 5 or 20 minute epoxy throughout ENTIRE construction.
PROs: Quality of parts, fit of parts, ease of construction, and looks.
CONs: None!
Finishing:
I finished the rocket with an orange body and blue fins and nose cone. There
are no decals and none are necessary to have a great looking rocket. Make sure
that excess epoxy is sanded down though.
Construction Rating: 5 out of 5
Flight:
I haven't flown this model yet, but it will fly first to 900 feet on an F50-6.
Recovery:
This rocket will descend under a 3 foot chute, which I think is the right size
for the big rocket.
Flight Rating: 5 out of 5
Summary:
This is a great big, fun rocket for beginners and advanced. It's ease of
construction are great for beginners and makes a great first epoxy rocket. It
was also my first 4-inch kit and the 4-inch tubing is massive! This is an
awesome rocket and it is worth the 60 bucks.

The following excerpt is
from "Sport Rocketry". The intention is to allow guests to get a
basic feeling about a kit. We strongly suggest that you get a copy of the
referenced Sport Rocketry and read the entire article. Inside you will find
many helpful hints in construction as well as other useful information. For

"When I look to buy a rocket, I want one that is straightforward."
". . . if the kit is built to the letter of the instructions, it doesn't
get any more basic."
". . . I'm impressed with the accurate fitting of each part, in particular
the centering rings and fins."
"LOC provides ample length of shock cord material . . ."
" . . . the fin roots did not extend all the way to the motor mount
tube." [by design]
"LOC's supplied [shock cord] mount is a strip
of braided nylon, which the builder loops and adheres into the airframe."
"I have had no troubles with it . . ."
"The first flights of my LOC IV were on a G80 motor, then a G64
reload."
"She boosted straight and true and cruised down under the 36" nylon
parachute."
"I chose an Aerotech H128 medium reload motor."
"Overall, I'm pleased with the LOC IV."
The entire article gives the impression is that this kit would be for intermediate modelers and those looking for their first medium to high power kit.
This kit was my Junior. Level 1 and I must say it is a beautiful kit. Some people say this rocket is not good for certifications due to the fact that the fins hang below the body. But, unless you land on concrete or desert, these fins are hard to break off. This kit is four-feet tall, four-inches in diameter and, coincidentally, my finished weight was four pounds. I tend to build heavy and ...
( Contributed - by Frank Ross - 11/11/00) Brief: Up-scaled to 38mm. Modifications: For my level-1 certification and my first high-power rocket I wanted a large, simple rocket kit without any bells and whistles. I chose the LOC-IV as I thought it looked to fit the bill, and wouldn't break my credit card. I decided to up-scale to 38mm rather than stick to 29mm because I liked the ...
Brief: An easy to build 3FNC rocket, built for my first shot with a reloadable motor. Construction: The kit contains a 4" kraft paper body tube, two centering rings (plywood) included, nose cone, 36" chute, elastic shock cord, 3 plywood fins, 29mm motor mount, and a 1/4" Launch Lug. This was a really easy kit to build. I spoke to LOC briefly regarding the fins, ...
- by Tom Bell Instructions: The instructions were complete and easy to follow. Although this is a large rocket, it was not difficult to build. The parts were well manufactured and fit together without problems. This kit was my first large rocket, and it is a good starter kit for large rocketry despite its imposing size. This kit requires epoxy for assembly of the ...
