Bo 105 1:5 - Fuselage kit

Ord.No. 6004

The "big Bo 105" from VARIO is a 850 size scale helicopter. You can power this remote-controlled model helicopter with gasoline (benzin), turbine or electric propulsion. Messerschmitt-Bölkow-Blohm (MBB), later bought by Airbus Helicopters, is the creator of the man-carrying version. The front doors and sliding doors can be made operational using the optional door fitting kit. You can also fit our fuel filling valve to the filler neck on the Bo 105 fuselage, see Scale accessories. This large Bo 105 helicopter uses mechanics based on the Acrobatic pod & boom helicopter.

For VARIO's 850 Bo105 CBS we recommend a maximum main rotor speed of 1000 rpm. Electric drive sets from VARIO are already tuned to this head speed.

Select one of the following drive types:

Benzin Acrobatic Mechanics

The benefit of a gasoline helicopter is a robust, easy-to-use engine for long flight times. The fuel is available at every petrol station (2-stroke mix). Kit Ord.No. 6004 contains the bulkheads for the gasoline Acrobatic mechanics. If the engine noise in flight does not disturb you, you will enjoy this classic drive system for model making. The VARIO Acrobatic mechanics were developed in conjunction with the VARIO Petrol mechanics to achieve a more maneuverable airframe that is better suited for aerobatic flight. This is due to the different arrangement of the mechanical components of this mechanics set. It can be flown as a trainer in pod and boom configuration, or in the Bo 105 fuselage. Other fuselage kits for this mechanics set are the Air Crane and the Agusta AW139.

Turbine Mechanics JetCat PHT3-L (mechanics and turbine)

The Bo 105 fuselage kit for JetCat PHT3-L can be ordered with Ord.No. 6005.

The turbine version fascinates by the smell of kerosene, a gently starting rotor, accompanied by the unmistakable sound of a turbine. Until the electrical power revolution in radio controlled model construction, turbines were the most powerful drives. In terms of flight times, turbines are still superior to electro-flight.

Electric conversion of the Benzin Acrobatic mechanics

Use kit Ord.No. 6004 for conversions of the petrol Acrobatic mechanics to electric motor drive. The strong and rigid aluminum side frames from the petrol mechanics are very suitable for the powerful electric motors being used in model helicopters today. Electric motors provide very quiet operation with low vibration, and no exhaust gases or oily mess to clean up. Model flights are much more realistic without the noise of the petrol engine, and the electric drive is so quiet that even the sound of the rotor blades can be heard in flight. Electric conversions are easy to accomplish using the suitable VARIO drive sets to achieve the optimum system speed for the 87:21 ratio. You may choose between 10S or 12S LiPo battery cells when selecting the conversion drive set that will be right for you.

Electric Mechanics Premium 1002/77

Our propulsion recommendation for this helicopter! Contemporary mechanics, especially designed for the scale model electric flight. The mounting points in the fuselage are identical to those of the turbine mechanics Ord.No. 1002/67. Therefore, the mechanics can be used in almost all kits that also fit these VARIO turbine mechanics with lower turbine position (in this case Ord.No. 6005). Electric motors are quiet, low in vibration, without exhaust gases and residual thrust. The blade slap noise sound of the rotor blades is more noticeable than with other types of propulsion and the result is a true-to-life impression in flight. For this electromechanical system we offer a drive set for 12S LiPos.

Benzin propulsion option - Build suggestion

First build a VARIO Acrobatic trainer (Ord.No. 8340) in the pod and boom configuration and fly, later install the mechanics in your scale fuselage. Advantage: You buy the mechanics components at a reasonable price and can learn the flying characteristics of the Benzin Acrobatic. The trainer mechanics can be built into all the fuselage kits Agusta AW 139, Air Crane and Bo 105. If you exchange the Acrobatic Trainer's 2-blade head to a multi-blade scale head, the reduction ratio must be adjusted. It is an easy conversion and the VARIO support network is always available to assist with the change.
