The Plus-Mechanics concentrate on the essentials. The clear, minimalistic design significantly simplifies installation and operation. Reducing the number of parts avoids tedious screwdriving work. In the fuselage, the mechanics are mounted on an integrated platform at four points only. The Plus-Mechanics has been developed by Scaleplus Models and has been in operation for several years. It can be configured according to the respective requirements of the model type.


The advanced design of the Plus-Mechanics breaks with the usual side-plate technology in a disruptive way. With its compactness it is almost invisibly accommodated in the upper portion of the fuselage. It does not stand in the way of an extensive interior scale finish. Nevertheless the mechanics are designed for full performance. Effectively, the mechanics perform exactly these three tasks:

- Distribution of engine power to the rotor systems
- Transfer of rotor forces and torques into the fuselage
- Control of the rotor system


The three servos of the swashplate are mounted in a frame, which is conveniently mounted with only two screws.

Remark: Images may show components which are not part of our program or are not included in the product.


The no-tail-rotor concept is realized by a variant of the PLUS-mechanics: a blower generates an air flow that is regulated by a variable nozzle at the rear end. The ingenious advantage: The mechanics in the tailboom can be omitted!

Safety Warning:
These helicopter models are not children’s toys! The handling of the models requires prior knowledge in model making and model flying. Improper handling can lead to serious accidents.
