On this page we would like to introduce you to the different variants of electric & turbine drives.

HF Electro-Mechanics XL Compact V2

An advantage of this mechanism is that independent of the main rotor speed (850 to 1400 rpm) the tail rotor speed 6250 to 9800 rpm is not changed (low torque and very good tail rotor / fenestron effect).

Ring gear and bevel gear in steel, the Dohm can be extended so that longer main rotor shafts can be used (at extra cost). It is also possible to install the servos horizontally or vertically (if there is enough space in the model). The mechanics are delivered completely assembled.

Rotor diameter: approx. 1.8 to 2.80 metres
Main rotor shaft: 12 or 15mm
Ring gear and bevel gear in steel
Main rotor speed: 850 to 1400 rpm
Tail rotor / Fenestron speed: 6250 to 9800 rpm
Motor: Hacker A80-8 for 10S Lipo power approx. 4,5KW (15sec.)
Motor: Hacker A80-10 for 12S Lipo power approx. 4,5KW (15sec.)
Motor: Hacker Q80-5L for 10S Lipo power approx. 7,0KW (15sec.)
Motor: Hacker Q80-6L for 12S Lipo power approx. 7,0KW (15sec.)

Prices: Mechanics 2.249,00€ without accessories / Motor A80- 559,00€ / Motor Q80- 679,00€ incl. 19% VAT.

HF3-XL Mechanics for PRO Tubes

The mounting points and tail rotor output are the same as our PHT 3 XL turbine mechanics and so it is very easy to turn an electric heli into a turbine heli or vice versa.

The Dohm can be extended so that longer main rotor shafts can be used (at extra cost). It is also possible to install the servos horizontally or vertically (if there is enough space in the model). In case of autorotation the tail rotor rotates with the model.
Mechanics are delivered completely assembled.

Rotor diameter: approx. 2.0 to 2.80 metres
Main rotor speed: approx. 800 to 1230 rpm
Tail rotor speed: approx. 6250 rpm
Window thruster speed: approx. 9000 to 9800 rpm (no intermediate gearbox necessary)
