The BO 105 by MBB Eurocopter is a pilot favorite. The small helicopter is fast, highly maneuverable, lightweight, and solid. It is favored by military pilots especially when used at tree top altitudes for support of infantry and ground units. The helicopter is also used as a police vehicle, air ambulance, rescue helicopter, and for utility operations.
Doors under the tail boom in the rear of the cabin open to allow up to 1,918 lbs. of cargo to be easily loaded on board. While not hauling cargo, there is room for up to six passengers. For medical use the helicopter can accommodate up to two paramedics and two patients.
Pilots enjoy user friendly instrumentation and controls of the BO 105 for sale plus superior downward visibility through the lower cockpit windows. The military version of the helicopter can be equipped with a radar mast and targeting system to allow tree top level missions. Infrared sights, doppler radar, spotlights, cameras, cockpit armor, and guided missiles are carried by the helicopter. Its twin engines and dual redundancy systems add extra safety to bring its crew back to base safely.
A great deal of the helicopter’s agility can be attributed to its one piece titanium hingeless main rotor head. It enables any control input from the pilot to be acted upon by the rotor head in about 0.2 seconds. In contrast, other helicopters use an articulated rotor head. The BO 105 for sale by MBB is the first production helicopter to use such a system. Its primary drawback is expense.
Helicopters throughout the years have used an articulated rotor system and most continue to do so today. In the system each blade is hinged and operates independently of the other. They can move vertically, forward and back horizontally, and are controllable in pitch movements.
The hingeless rotor uses motion and vibration control components rather than hinges for greater control of horizontal and vertical movements. Vibrations are greatly lessened and input response lag time is much improved.
In some cases rotor oscillation can happen so fast and become so extreme that airframe damage can not be avoided. This effect is known as ground resonance. The danger of strong vibrations and shock from the landing gear passing through the fuselage causing an imbalance in the turning rotors of the helicopter while on the ground are greatly diminished with a hingeless rotor system.
The BO 105 may be found in some forty countries around the world. Over 1,500 BO 105 helicopters were built before production ended in 2001.
The BO 105 from Martin Sollner is a giant scale model powered by a Jakadofsky turbine with a 122″ rotor diameter. Length is 124″, height is 39″ and weight is about 42 lbs.
The BO 105 fuselage from Vario comes as a 13 piece kit that is available for gas or Sky Fox mechanics. It has a 63″ rotor. Length is 63″ and width is 10″.
