M-Tron: 6923 Particle Ionizer

Wouldn't it be nice if Helicopters were spacecraft???

Legoland space is not populated with very many helicopters.  In fact, there is only one.

This is 6923 Particle Ionizer, or in Britain, Cosmicopter; I will use them interchangeably through the review.

This is M-Tron's most popular and sought after set.  Among the M-Tron sets this was one of the more frustrating space sets for me to seek out since prices tend to be inflated.  Somehow I managed to beat the odds and got a cheap barely used copy in immaculate condition from C&M Brickshop.  That shop is currently closed, but I highly recommend them if they ever start selling sets and parts again.

6923 Particle Ionizer is something of a combat ready cargo helicopter.  Its plasma rotors cut through the vacuum of space and allow the craft to dodge around asteroids faster and more precisely than the best top of the line thrusters.  This is M-Tron's chariot of war for defending against their devious Black-Tron adversaries.  When a downed Futuron vessel needs help in a hotspot, send in Cosmicopter to the rescue.

Speaking of defense; Cosmicopter comes with a truckload of options.  The front cannon can atomize heat shields, and the wing mounted lases can chew threw exposed hulls.  Thrusters at the aftmost part of Particle Ionizer enable it to rocket forward and close on the enemy in open space.

Particle Ionizer comes equipped with a supply of tools and fuel to repair damaged vessels.  In a pinch it can drop and go.

Walky Talky

Wrench

The package has a beacon, and carries fuel inside

And an assortment of tools to complete any job.

Quite the assortment for a middleweight set.

The crane on Particle Ionizers back is remarkable for its full function and maneuverability.  In many ways the loss of these classic hinges was a heavy blow to some of the Golden era's coolest tricks.  The current use of clips and click hinges has filled the void but lacks that close fitting connection that made these things so sleek and compact.

Cargo stows snug in the back.

Handlebar grips hold the cargo firmly in place, and the back tail fins can drop to allow full function cargo removal.

The crane can swing the cargo out.

And around.  The design is very exacting, but doesn't feel limited by its function.

The rotor and crane are designed to easily rotate without obstructing each other.  Absolutely flawless engineering.

A servobot stows away amidship and can assist with dangerous repairs such as radiation leakage.  It can also perform simple repairs remotely while Cosmicopter defends the perimeter.  It's boxed in on one side to keep it snug in its compartment.

The right side access hatch allows for removal.

And you have now accessed a Servobot

The servobot contains several bits that aren't in any other M-Tron sets.  We'll check those out in a moment.

As a toy Particle Ionizer is a fine example of what made the Golden era so good.  It contained excellent engineering, slick design, cool functionality, and storage compartments.  Building it was as much fun as fiddling with the final model, and the part well is deep and enticing to new builders and hardened veterans.

Particle Ionizer brings a lot of elements to M-Tron's catalogue of parts.

First up is this unique color variant.

1.  This gigantic brick is rare in the color red.  It's listed as being in two sets by Peeron, but to build the other set, (Secret Space Voyager), you need Particle Ionizer.  This red part is unique to this set.  It's great for SNOT as it has a lot of surface area for structural reinforcement.

The remainder of the parts vary in quantity and there're plenty of special bits hidden within this set

1.  This part is a staple of SNOT technique.  You only get one in this theme so use it well.

3.  What can I say, common, but none of the other M-Tron sets have it.  The tapering edge is great for smoothing out your designs.

1.  Common, albeit, not at all prevalent in Lego Space.

1.   Common part, the red variant is available in Stellar Recon Voyager, but this is the only black version in M-Tron.  This part can be useful for some inverted SNOT techniques.

4. This base clip is equally prevalent in red and black within M-Tron, but this set has the M-Tron lock-down on black base clips.

2.  This old gray control stick composes part of the robot, and is very common.

2.  And here is the base for the control stick.  This black version is an ordinary piece that is easy to come by.  You wouldn't know it to look at just the M-Tron theme.

2.  This is the most common color for these hoses.  I always liked these parts.  They offer some fun dynamic construction methods, but they suffer from somewhat frail connections.

2.  These two gray goblets make great thrusters between glasses of sparkling cider.  Sadly their supply is restricted to Particle Ionizer.  Fortunately it's an easy piece to come by in other themes.  If you need gobs of them save up for the collector series Imperial Star Destroyer.

2.  This is a fairly ordinary part in a prevalent color.

2.  This grey piece is a common part.  Grey is the trim color for M-Tron so there isn't a lot of it available within the theme.

2.  This is a fairly common corner plate developed for the Futuron era.  It's always annoying to get just one, so have two.

4.  This is a pretty common piece from the Futuron era.  It's a good one to have for streamlining designs, which was not as easy in the Golden era as it can be today.

1.  It's an ordinary 4x8 red plate...Nothing to see here. Or is there?...possibuildities await.

1.  A 6x8 Black plate, perfect for establishing the foundation of your model.  It's not rare.

1.  Aargh, yah only get one red inverted slope.  The fiends are holding out on us!!!  Good thing M-Tron doesn't have the only one.  It's otherwise common.

4 is so much better.  Use these to streamline your ship.  This part is a common drop item.

1.  This is a rare print, available in only three sets.  It's good for texturing models.

1.  The ever delightful space console.  I cried when I realized it had gone out of production.  It's especially useful in cockpits, and it's such a nice looking bit.  Trivia: The last set to ever use this piece was actually a reissue of the perennially best selling 7140 X-Wing.  The re-issued set is labeled 7142.

2.  This wing/tail piece is somewhat common in red, it appeared in several sets from 1988 through 2005, and given the continuing presence of the part type, it's likely this will continue to be a readily available piece.  It's a good one.

1.  I have never broken these flat clips; that ranks them as my favorite of the clip types.  That being said, this is a good part to have in the collection for dynamic connections, and since it's old gray, be careful with it.  They don't make this color anymore.

1.  My first turntable was this color.  I got mine in 6375 Trans Air Carrier (Also responsible for my first minifigures) and immediately loved the part.  It's a simple effective part for giving your model a sense of motion.  This is the only one tone variant of the part since the center is always grey.

1.  The shaping on this inverted wedge is excellent for giving your models a sleek look.  Sadly, there's only one in M-Tron's main collection.  It's somewhat common otherwise, and still in production.

1.  This old grey tapered plate is a good addition to M-Tron's limited supply of grey trim.  Newer versions of this part have notches in the taper that make it more useful for building inside studs, but destroy the smooth edge.

1.  This wing cutout is the first version with the 4x4 cutout, this is a rarer part type than the 3x4 cutout version.  Like many parts, both appear to be out of production.  It was only available in two sets, but is required in both of the Super Model instructions for M-Tron and Black-Tron.

1.  This red hinge plate is somewhat uncommon, and the supply restriction is even worse here.  It's good for moving segments, and dynamic shaping.

1.  This hinge plate is comparatively more common than the above.  Kind of weird, but even in this set the two are not connected together.  It is used for function in this model, but can also be used for dynamic shaping.

Particle Ionizer is a sizeable model and I expect the alternates you can make out of this could be pretty cool.  Here's what the Lego designers came up with.

Let's see, two spaceships and what looks to be an earth digger/crane of some sort.  These are some of the cooler alternates I've seen on the back of a box.  For all intents this set looks ready for the first time collector.  It also happens to be a favorite among serious Lego collectors too.

Here're some of my alternates.

Colorblind

We're gonna need a bigger boat.

Putting the red in Red Leader

To sum up Particle Ionizer is an excellent set.  It is one of two M-Tron sets that put this theme on the AFOL radar, and a perfect example of why the older Lego fans rightly remember them as the good old days.

Final Score: A
Pros: Strong/varied part selection, excellent play features, Unique Red Brick.
Cons: ??? You're Serious?  I just built a frickin X-Wing.

Next time, we're going to look at the three set marketing gimmick known as
6862 Secret Space Voyager...
