PETROL Acrobatic

The BENZIN Acrobatic Trainer is the latest version of the Benzin Trainer with the engine repositioned forward for better weight distribution. The acrobatic mechanics use the same drive components as the proven Benzin Trainer.

The mechanics are suitable for installation in the following fuselage models: Agusta AW139, Air-Crane, Bo 105.

It is available in six different combinations:

with rotor disc Ø 1630 or 1780 mm

with flybar head or flybarless version

with or without engine / silencer.

Two versions have a smaller rotor diameter of 1630 mm.

The 'BENZIN Acrobatic' trainer model is specially designed for the use of a Zenoah G240 23cc engine.

Max. permitted rpm is 1400. For the required rotor diameter of 1780 mm, only use rotor blades no. 422 at maximum rpm. This design is intended for aerobatics with the trainer model. For installation in a fuselage, note the specified gear reduction, which can be changed simply by swapping the gears.

The main and tail rotor blades are included in the kit.

The model is supplied as a kit, i.e. unassembled.
