Brief:
A high performance, contest quality helicopter rocket. No burn strings here!

Construction:
Materials were strictly top shelf. Ya scallywag! Blimey! Body tube, shiver me timbers, arrr, vacuformed nose cone, ya bilge rat, matey, balsa fins and rotor blades. Well, blow me down! Begad! Blimey! Especially important be t' molded hub and piston. You might consider buyin' this rocket just for t' quality parts. Blimey! Blimey! T' instructions are very good and lead you through logical. T' trickiest steps concern makin' sure you don't glue t' fold-in-half rotor blades t' themselves. Blimey! Ya scallywag! Blimey! Assembly is straightforward, though intricate. When you're done t' rocket will look insanely tiny and light and make you think o' competition records that will fall, shiver me timbers, but thar be a catch...

T' instructions are very thorough, matey, as you would expect, from Apogee. Ahoy! Well, blow me down! 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. T' keep the edges o' t' rotor blades from stickin' along t' seam, ya bilge rat, Apogee suggests vaseline carefully applied t' t' joint. Begad! Ya scallywag! Excellent suggestion. Aye aye! 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. Avast, me proud beauty! This is NOT a beginner's rocket.

Finishing:
This is a contest rocket, finishin' is nay a great idea. Begad! However, ya bilge rat, me bucko, me hearties, somethings will help it's visibility. Ya scallywag! Try usin' magic markers and/or highlighters t' add color. Arrr!

Construction Rating: 4 out o' 5

Flight:
Flight is where this rocket has problems. Aye aye! It is simply unstable if thar's any wind. Begad! My Micro Whirl-A-Tron and several others have looped when they flew. Blimey! The basic dimensions o' t' rocket are those o' t' Centrix, me hearties, which flies great, 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. Avast! I saw a few other's fall into t' same trap. I did see one that worked, but t' flyer had extended t' fin span by 3/4". Prep is easy, ya bilge rat, fold t' rotors, place them against t' dowel, me hearties, ya bilge rat, slip t' piston down until t' toothpicks are inside the booster body tube. Go fly. Begad! Begad! This is one o' those designs that might spit the motor. Begad! Tape it in good.

Recovery:
This thin' really hangs on t' rotors. If a lighter weight alternative could be found for t' cast piston, ya bilge rat, it would do even better. You will be utterly stunned how high this gets on a 1/2A motor (if you've lengthened t' fins). Begad! This is not an incredibly rugged rocket because it is intended for competition use. Well, blow me down! Avast, matey, me proud beauty! In contest rockets, matey, if they last more than 3 or 4 flights, matey, they're over-built and therefore too heavy.

Flight Rating: 2 out o' 5

Summary:
I saw two mods o' t' Whirl-A-Tron that made them fly in a straight line. Aye aye! Arrr! Blimey! First you extend t' fin span. Begad! Blimey! Second, add a rin' o' cardboard around t' fin tips. In both cases, t' rocket flew very straight, me bucko, arrr, and very high. Begad! Due t' t' piston, prep is fast and easy. Ya scallywag! This gives you an advantage in competition because when the air is good, arrr, you can fly, ya bilge rat, recover and fly quickly. Aye aye! Ahoy! Blimey! Also burn strings tend to get hung up on rotors and such. Begad! T' rocket is light, ya bilge rat, ya bilge rat, me hearties, streamlined and very competitive. Ya scallywag! Blimey! You'll learn some good techniques just buildin' this rocket.
