You’re hearing thunder from above, and a deep, yet high-pitched, turbine-like sound? Then you better beware of the Bear…
Kasteleiner Aircraft & Aerospace Industries proudly presents the MH-81 “Bear”, a medium-to-large, heavy and heavily armoured multi-purpose helicopter. Flown by a pilot and a co-pilot, the Bear serves as a mighty gunship, troop transporter, heavy lifter and rescue helicopter in many of the world’s military fleets.
About this creation
Machine canons, optional multiple rocket pods and machine guns from the sides make a hovering fortress out of the Bear. Two side-mounted extendable crane arms allow off-board transport of oversize cargo, rescue and heavy-lift missions. The fuselage widens in the back of the chopper and offers lots of space for troops and cargo.
Due to an enormous rotor diameter (55 studs), massive rotor blades and three high-powered turbo shaft engines, the Bear's lift is considerable. The result of this is a rotor downburst knocking the toughest soldier off his feet…
In spite of his relative massiveness, the MH-81 “Bear” is designed to be transported – via special trucks on the ground and large cargo aircraft in the air: no area of the chopper is wider than 10 studs. “Wider” areas can be detached (rocket pods) or flapped in for transport (main rotor, rudder of altitude). This guarantees extreme mobility and flexibility needed during diverse military operations.
Due to a newly developed helicopter fly-by-wire system, the Bear can perform high-precision landings and take-offs on and from mobile platforms such as trucks.
Design features & functionality
- The Bear is almost entirely based on SNOT techniques; the whole fuselage except from the top and rotor part has studs pointing (or rather NOT pointing) in multiple directions. Just check out the pictures and you will find some more details…
- Tiltable rotor blades on both the main and the rear rotor
- A forwards/backwards tiltable main rotor
- Little extendable stairs
- A very easy-to-open top for playability purposes
- Detailed cockpit interior

- Length: 56 studs
- Rear rotor diameter: 9 studs
- Maximum height : 19 studs (at tail rotor with horizontally tilted main rotor)
- Maximum width of fuselage: 10 studs (at rocket pod holders)
- Landing gear: non-retractable construction; 3 x 2 wheels
- Powerplant: 3 x Skydyne Systems SHS-330 “Whirlwind” turbo shafts with 2206,5 KW
(3000 HP) each
- Empty weight: 9660 kg
- Maximum take-off weight: 19890 kg

Optional additional and/or alternative armament (not depicted on pictures):
- Manual machine gun on each side
- Larger rocket pods with 9 or 16 Taipan R.81 each or combinations with other missile types (Cobra R.13; X.21 "Exterminator"; etc.)
Mechanics at work...
Side profile: I wanted to create a beautiful, long tail and not one of those "prolonged" fuselages such as seen on the Super Stallion, for instance. That means less cargo capacities, but better esthetics...
That is also one of the reasons why I decided not to build a ramp, and to go with just the side doors and the dual crane system for oversize cargo.
And let´s not forget: The MH-81 is NOT a pure transport helicopter, but a gunship as well. Versatility is the key...
Transparency... with the help of transparent slopes and "mini slopes", one can imitate the typical rounded shapes of cockpits.
Dual crane system for oversize cargo and rescue missions. Apart from that, the picture shows well the functional tiltable rotor blades and the forwards tilted main rotor.
The chopper with a silhoutte of the transport truck in the backround...
A very easy-to-open, yet very sturdy cabin held in place without the help of studs: very practical for playability purposes... Can you tell that I love to play? :)
And one of my favorite, indeed small but very helpful details: extendible stairs on both sides to enter the cabin.

A Bear loaded on a special truck. Precision take-offs and landings off these mobile platforms belong to the repertoire of the bears mobility capacities...
Some of you might have noticed a few similarities which the chopper shows in regards to the real-life Aérospatiale/Westland "Puma". The Puma indeed served as a main inspiration for building the "Bear" - which turned out to look like a heavier, bigger chopper than the "Puma".
Thanks for rating and commenting; constructrive criticism & feedback are welcome!
Great job on making it look beastly - like a bear - because it does! Really sweet heli but that truck/carrier is awesome. I could foresee a special ops team driving the heli around and then taking off when it's time for business. Nice work!
Fantastic job! I like the continuity of the fuselage, no blockiness. Very nice.
I like it

Hey Steffen, this is truly some excellent work right here. The curvature of the rear fuselage where it forms the tail boom is very aesthetically pleasing. The overall profile is astounding and is a unique style I've yet to see in a LEGO helicopter. This is a great work and I'll be sure to have to 'borrow' some of it's components for later projects of mine haha.
