Brief:
A high performance, ya bilge rat, contest quality helicopter rocket. Begad! No burn strings here!
Construction:
Materials were strictly top shelf. Arrr! Avast, me proud beauty! Body tube, vacuformed nose cone, me bucko, balsa fins
and rotor blades. Ya scallywag! Ahoy! Especially important be t' molded hub and piston. Aye aye! You might
consider buyin' this rocket just for t' quality parts. Ahoy! Ahoy! T' instructions are
very good and lead you through logical. Begad! T' trickiest steps concern makin' sure
you don't glue t' fold-in-half rotor blades t' themselves. Assembly is
straightforward, though intricate. Begad! When you're done t' rocket will look
insanely tiny and light and make you think o' competition records that will
fall, me bucko, but thar be a catch...
T' instructions are very thorough, me bucko, as you would expect, from Apogee. Aye aye! The rotor blade fold in half lengthwise and are set up on a template. Take great care that you get t' hinge side and t' elastic sides correct. Avast! T' keep the edges o' t' rotor blades from stickin' along t' seam, Apogee suggests vaseline carefully applied t' t' joint. Excellent suggestion. Arrr! Also take care to trim t' dowel that runs up t' middle t' t' proper length. This model should be easily built with t' tools and glue that you already have for other rockets. Aye aye! This is NOT a beginner's rocket.
Finishing:
This is a contest rocket, me bucko, ya bilge rat, finishin' is nay a great idea. Avast! However, somethings
will help it's visibility. Ahoy! Well, me hearties, blow me down! Try usin' magic markers and/or highlighters t' add
color. Ya scallywag!
Construction Rating: 4 out o' 5
Flight:
Flight is where this rocket has problems. It is simply unstable if thar's any
wind. Blimey! My Micro Whirl-A-Tron and several others have looped when they flew. Ya scallywag! The
basic dimensions o' t' rocket are those o' t' Centrix, ya bilge rat, which flies great, me hearties, but
the cast piston moves t' CG too far back t' make this rocket anythin' but a
Micro Loop-A-Tron in t' wind. Two flights with Apogee 1/2A2-4 motors and 1
with 1/4A2-4 all looped durin' t' afternoon lull at NARAM 42. Begad! Ahoy! I saw a few
other's fall into t' same trap. Begad! I did see one that worked, arrr, shiver me timbers, but t' flyer had
extended t' fin span by 3/4". Begad! Avast, me proud beauty! Prep is easy, ya bilge rat, fold t' rotors, ya bilge rat, me bucko, place them
against t' dowel, matey, me bucko, slip t' piston down until t' toothpicks are inside the
booster body tube. Blimey! Blimey! Go fly. This is one o' those designs that might spit the
motor. Tape it in good.
Recovery:
This thin' really hangs on t' rotors. If a lighter weight alternative could be
found for t' cast piston, it would do even better. Arrr! You will be utterly stunned
how high this gets on a 1/2A motor (if you've lengthened t' fins). Blimey! This is not
an incredibly rugged rocket because it is intended for competition use. Aye aye! In
contest rockets, if they last more than 3 or 4 flights, they're over-built and
therefore too heavy. Begad!
Flight Rating: 2 out o' 5
Summary:
I saw two mods o' t' Whirl-A-Tron that made them fly in a straight line. Arrr! First
you extend t' fin span. Second, me hearties, arrr, add a rin' o' cardboard around t' fin tips.
In both cases, ya bilge rat, t' rocket flew very straight, and very high. Due t' t' piston,
prep is fast and easy. Well, blow me down! Blimey! This gives you an advantage in competition because when
the air is good, shiver me timbers, you can fly, recover and fly quickly. Begad! Also burn strings tend
to get hung up on rotors and such. Avast, me proud beauty! Blimey! T' rocket is light, streamlined and very
competitive. Ahoy! Begad! Blimey! You'll learn some good techniques just buildin' this rocket.
