MX-81 Hypersonic Operations Aircraft
Posted: May 31, 2009
"The MX-81 H.O.A is, so far, one of the best Mars Mission sets I've bought. The play features are okay. The minifigures are cool, but the alien commander is the figure I'm crazy for.
Pros:
*Huge
*Fun to play with
*Got rare pieces in it
*Minifigures
*Alien commander
*The Ship itself
Cons:
*Heavy
* Expensive
*Hard to seat the alien commander
A few cons, but mostly a positive review for this Lego Mars Mission set."

Excellent Set!

"I got this set on sale at only US$48. This made it impossible to resist.
It's big and has many good features like the swing down buggy platform and the crystal lab hidden between the cockpits. The orange and White color scheme looks brilliant as well. The alien fighter is a good addition as well."

AWESOME
Posted: April 13, 2009
"This is one of the best sets that I ever got. The landing pad mechanism worked better than I expected, and although there is an alarming snap when I open or close it, I checked inside and nothing was wrong. The ship itself has a complex design, and when I was done building it, I wondered where in the building process it vaguely resembled this! I overall liked the set and thought it was a great buy.
The mining vehicle is standard, nothing fancy, but I think a complex design would draw attention away from the ship. The alien ship included the alien commander and had "fold up" build, as I call it, which refers to how the wings are placed. It's pretty sturdy and I think there was a great job on the design.
Overall, I would recommend it to a friend even though it was a tad pricey(but only by about 5 bucks)."

Beautiful set
Posted: March 31, 2009
"I have been very impressed with the designs of ALL the Mars Mission sets, but this one in particular is stunning. The human ship is a work of art, and very fun to assemble.
I have really enjoyed that most of the large ships in this theme have smaller ships built into them - that really adds to the playability of the sets.
The alien ship, though small, is solidly designed and doesn't look like an afterthought.
A very solid set, and a great purchase!"

MX-81 Hypersonic Operations Aircraft
Posted: February 11, 2009
"Well I have to say this set was the post disappointing Lego set I have ever bought.It was a complete waste of money.When I brought it home the day I got at Lego Land, I built it all with in three hours.And the part for getting out the landing pad was totally awesome.But after maybe the third time i brought the landing pad out,it broke.So,when i took it apart to see whats wrong,it turns out the piece that hold the rubber band broke.And believe me,it was a pain trying to fix it.So I some how fix it,but then the second time I take the landing pad out, it breaks again.So now I just have the broken ship on one of my tables. So I would definitely not advise people to buy this product.But it is fun to play with."

MX-81 H.O. Aircraft
Posted: February 10, 2009
"This set is simply amazing. From the wheels of the mining vehicle to the handle you can use to hold the set, this thing provides hours of fun! It took me about four hours to build this complex model. the first thing I noticed when I opened the box was the suprising amount of special elements and the GIANT rear wing piece. The alien ships don't really do it for me, I will admit the there are many rare elements on the alien ships, but the builds and final products are rather boring. The human ship is, like most large sets, amazing. This ship is just glowing with weapons and lasers. As well as many rare elements and pieces. The two cockpits on the side detatch to become scout ships, leaving the "research" lab open to play with. Also, the small blue "button" is a neat contraption that releases the holder for the mining vehicle. Overall this set is a great addition to any Mars Mission collection at a decent price."

Excellent Ship.
Posted: January 30, 2009
"I think that the MX-81 Hypersonic Operations Aircraft is brilliant. I bought it at a discounted price which made me want to get it even more. I would recommend this product to my friends. I like it that my bro has the ETX Alien Mothership Assault so I can use this ship to fight his.
Pros:
-Cool alien ship.
-Comes with good amount of minifigs.
-Nice little drill truck.
-Detachable ships.
-Cool alien commander.
Cons:
-Repairing the ship if it breaks. (this is very unlikely but I ended up dropping it from the top of my bunk bed)

Freakin' AWESOME!
Posted: January 28, 2009
"I can't say much that hasn't already been said in other reviews, so I'll keep it brief. This set is awesome. I'm an adult - I build LEGO as a hobby - but I couldn't stop myself from running around the room holding the two ships making engine and laser noises. It's one of the best LEGO space ships of all time, made even better by the fact that it's an homage to another of the best LEGO space ships of all time (the Deep Freeze Defender). Buy this set. Buy it if you're a kid. Buy it if you're an adult. Buy it if you've been lost on a desert island for decades and can't remember your age. It's a must have."

Awesome Spacecraft!
Posted: December 26, 2008
"Hi. I got this set yesterday, and I think it's simply AWESOME! It's huge, and Is very fun to play with, but I think the Alien Spaceship can have functions. First, we will see the Pros and Cons:
MX-81 Operations Spacecraft:
PROS:
*Giant size (If you like giant things)
*Cool design (Many pieces)
*Interesting astros
*Elevator Function (I love it!)
*Color scheme (I really like orange, white, and bit of black and blue)
*Tons of blasters
*Some new and cool pieces
*Divides into five spaceships.
CONS:
*Laboratory is quite small
*The part near the handle is a bit fragile
*Alien (normal) is not very movable
Alien Spaceship
PROS:
*Cool design, it seems speed and powerful
*Cool stickers
CONS
*The Alien Commander is hard to put him and bring back him outside of his ship
*The vehicle can have functions
OTHER
-If you don't like stickers, then this will be a con. But if you are good to put them, this wouldn't be a problem.
-Alien commander is cool, but can have a better design. (Main body is cool, but legs and arms didn't (Possibly because they are the same piece))
-If you tought that the drill spin when the little vehicle moves, (As seen in the video "The Alien Hive") this is false.
-I am a lover of the giant quantity of pieces. I you aren't, this will be another con.
-ENJOY!
-Ahh! I am waiting an Alien King!
Overall, this set is awesome! I grant it a 4.9/5. I mean, the only con that makes sense is the lack of functions on the alien vehicle.
So, I would recommend you buy this set. It's, like I Said, an Awesome Spacecraft!

Death From Above!
Posted: December 25, 2008
"I love this toy! The play experience is great. It is fun to mess with the plane. The main body has a handle made of Technic pieces which allows you to hold it. The lab inside is neat, but can not fit a minifigure. This plane has three small scout ships. The main two detach, and have great cockpits. Detailed! The last is a small satelite, which I prefer to use as an EMP cannon. Last of all, a platform will deploy from the back of the plane with the push of a button near the handle. It carries a mining vehicle. The alien ship is compact, sturdy, good looking, and neat. Its stickers are prismatic, making an etheral effect."

Best lego set ever!!!!
Posted: December 24, 2008
"This is the best set ever! I like like the MX-81 D and MX-81 E (air defence flyers). The MX-81 B satellite is also cool. THe set flyes with a Crystal-energized plasma boosters. The best part of the set is the MX-81 A lab section. The weapens on this ship are 14 Ionized cabalt ray guns, and 1 KRUNP-11 rocket launcher. I would recemend this set for lego lovers."

perfect replacement
Posted: December 14, 2008
"I bought this set just yesterday. It was quite a bit but worth it since the command base isn't very good.
Pros:very large
perfect for a mobile base
Alien commander with a pretty nice ride
Cons:pricey
all weapons face forward
the wing on mine on 1 side is bent
interior needs a little bit of tweaking to put a pilot for the whole thing inside
No see-through windsheild(not about the defense flyers)
Overall the satillite looks more like a super ray gun when on the main unit. It's ok but, a few turrets like the alien mothership would do good and since the command base is no longer avalible, this is why i called the review "perfect replacement"

"This set is cool, yes, but I just don't see anything extremely unique about it. It is fun though to play with the operations aircraft and pretend to do rescue missions with it, but there's really nothing extraordinary about it. I will concede that the alien ship is quite sleek."

"The MX-81 Hypersonic Operations Aircraft is cool looking, but incredibly fragile. The alien ship, on the other hand, is incredible in every way.
Pros:
lots of guns
can divide into five ships
alien ship is very sleek
lowering platform works well (when it's not broken)
Cons:
Main lab falls out when you try to remove side ships
The platform isn't sturdy enough to support the weight of the ship
The rubber band supporting the top button falls out frequently (It's really hard to put back together!!)

Exelent job LEGO
Posted: October 26, 2008
"I think this is an excellent set. At the front are two little astro fighter things that come off. At the top there is a satellite. It even has a little mining unit. It also has an elevator for the mining unit to go on to get onto the aircraft, to the ground, but the ship is kinda pricey, but I think it's worth it."

Head Aircraft
Posted: October 13, 2008
"Before the pros cons list, I will first compare it to the the Armoured Drilling Unit. This was way bigger than the Armoured drilling unit, the permiter, at least, but its easier to build than ADU. It doesn't consist many technic bricks like the ADU, but still quite a few. The hardest part to build was to push those red pegs to lock the bricks up. But other than that, its about it. One more note this thing will make even the mothership scream ''mommy!''.
Pros:
Very impressive size
Awesome features (The lowering platform especially, its awesome!)
Loads of guns
Detailed
Cons:
3 (2 on the ship, 1 on the driller) astros to pilot this big mother of an assault ship?
This ship is a bit heavy if you hold the ship using the handle.
VERY fragile satellite
HORRIBLY designed interior!
But overall its quite good. I added one astronaut from the 5616 and another one from 7646 to look after the lab.
