Rotor head:
Rotor head. It uses SKF bearings and is designed for gyroscopes up to 400 Kg MTOW. The torque tube is longer so that various components can be fitted. Swing towers use approaches.

Double-bearing rotor head. It uses SKF bearings and is designed for Gyros up to 560 Kg MTOW.

Slider. Minimizes stick shake 2 per turn
Brake rotor
Mechanical pre-rotator:
Our mechanical pre-rotator fits Rotax B, C, and E rotor heads and transmissions with a proper engine installation and a downshift. The motion transmission is via a ½” (12.5mm) bend shaft. It is capable of 220 rpm of the rotor.
Recommended pre-revs are 150-160rpm as the ground travel will only be about 5m longer, and the stress on all components is 50% less, so a much longer service-free life can be achieved.

Pre-Rotating Amplifier:
The world’s lightest efficient pre-rotator. The head unit, including the ring gear, is only 1.8 Kg (4 lbs). The complete setup with all cables, hardware, and electronics is 8 lbs (3.6 Kg). Batteries range from 1.4 lbs (0.6 Kg) for the lithium types, which cannot be charged in flight (UL system), to 10 lbs (4.5 Kg) for the sealed lead acid types, which can be set during the flight.

The pre-router is capable of 140 rotor revolutions but is designed to remain engaged during ground travel, thus effectively boosting wing acceleration for a short takeoff. The overall effect is like spinning the blades with a mechanical pre-rotator at 200+ rpm. Blade acceleration is slower than the mechanical pre-rotor and puts less strain on the rotor system. They are limited to 2 minutes of operation at a time. Care is needed to avoid overheating the system with repeated pre-rotations. Lithium batteries can be charged within 30 minutes to 1 hour in the car (on the way to the airport), and lead batteries, if empty, can be trusted enough for a pre-spin within 10 minutes with the engine running.

Rotor Blades:
The rotor blades are 6061T6 aluminum and use a skin-welded construction method. This makes the fins light and robust. Because they are built this way, they are the ONLY blades with a positive twist, allowing them to outperform any other rotor system available today.

Also, the airfoil used performs better than the standard 8H12 used by other manufacturers. The fins also have tip weight to provide high inertia with low weight. These fins are available in sizes ranging from 22 to 29 feet. Wings come with matching hub rods and are always test-flown before shipping. Due to their high performance, these vanes cannot be started by hand.

Gyro Stick:
The Gyroplane stick can be used on most gyroplanes. All axles use self-lubricating Olite bushings and Teflon friction washers. It is lightly built and extremely strong. It is designed to fit into a 2″ x 2″ square pipe with a 1″ rod.

We can also supply an extra set of plates to move the lever position 5 degrees forwards or backward. The combination provides 14″ (35 cm) of travel.
