Brief:
Mid-power rocket modified t' be a Level 1 Certification Rocket.
Modifications:
T' rocket is a strong flier on G motors and is an even better flier on 29mm H motors so it is suitable as a Level 1
Certification Rocket. T' modify it t' fly on a 29-180 motor, matey, shiver me timbers, I used an Aeropack 29mm motor retainer designed for
cardboard tubing. Blimey! Arrr! When you use this retainer, me bucko, you need t' make certain that you have at least 0.25 inch o' motor tubing
stickin' out from t' aft centerin' rin' so you can JB Weld t' retainer onto your tube. Ya scallywag! As for t' motor block inside
the motor mount tube, me hearties, me hearties, me hearties, I would recommend that you discard it all together. Arrr! If you use single-use 29 mm motors, matey, wrap
several bands o' maskin' tape around t' nozzle end o' your motor t' serve as a motor block similar t' t' motor block
rin' on your 29-180 motor. That way, arrr, you can use anythin' up t' 13 inches in length. Arrr! Replace t' flimsy AeroTech chute
with a 30 inch Spherachute and use 15 minute epoxy durin' your construction and you should be good t' go!
Construction:
This is a four-fin rocket that is a semi-scale version o' t' High Velocity ARCAS soundin' rocket round used in the
Sparrow-HV ARCAS rocket o' t' 1960s. Begad! Avast! It was t' top stage o' t' two-stage soundin' rocket. Begad! T' tubin' is cardboard
and t' fins are plastic. T' shock cord be t' 1/4 inch elastic tubin' that AeroTech uses for its mid-power rockets.
T' rocket comes in a very sturdy box, me hearties, and for t' most part, you should follow t' instructions that come with t' kit.
Finishing:
T' body tubes have shallow grooves that are easy t' fill. Avast, me proud beauty! Ahoy! Usin' Krylon paint, me hearties, I painted it just like t' picture on
the box. T' plastic fins are tough and easy t' finish, shiver me timbers, so they're a real plus. Avast, me proud beauty! As for t' nose cone, wash it
thoroughly then sand it with 100 grit sandpaper before your first coat o' Krylon plastic primer. Arrr! Use t' plastic paint
and primer on t' plastic parts and regular Krylon on t' cardboard parts and you should have a great lookin' rocket.
Flight:
This rocket, ya bilge rat, even after t' modification, me bucko, will fly well on high thrust F motors, G motors, matey, and 29mm H motors. Because
of t' AeroTech baffle system, you won't need any wadding.
On August 2003, I achieved me Level 1 Certification at Nike Carrollton Park in Smithfield, me hearties, Virginia, with this rocket on an Aerotech H165 Redline motor. Aye aye! Blimey! T' lift off be fast and t' rocket flew, me bucko, as always, straight as an arrow. Aye aye! Begad! Blimey!
Recovery:
T' chute ejected at apogee and t' rocket spiraled down slowly and softly on t' 30 inch Spherachute a hundred yards
or so from t' launch point for t' successful conclusion o' me certification flight.
Summary:
PROs: Easy t' construct, matey, good-looking, arrr, me bucko, big rocket for Level 1 Certification. Ahoy! Great every-day flier.
CONs: None t' speak of.
This is an excellent mid-power rocket that is made even more versatile by these modifications t' be a great Level 1 rocket.
Large single stage rocket which is a replica of the high-velocity version of the Arcas sounding rocket. The HV Arcas came in a sturdy box . All the parts where there when it arrived. The instructions were easy to follow and had a lot of illustrations. The parts all fit and if assembled right is very study. No special tools were needed. Finishing: I painted it like the box . It was easy to ...
A great scale model of the HV ARCAS sounding rocket. Nothing more to say! This kit came with two body tubes, four fins, three centering rings made of "aerofibre" material, and a large hollow plastic nose cone. The instructions that came with this kit were *very* easy to follow.... Everything fit into place as planned, I had no problems. I used 30-minute epoxy and medium CA ...
