Introducing our meticulously crafted Helicopter Cyclic Control System, one of our most exciting designs to date. With over 28 years of helicopter expertise, our goal was to achieve unparalleled realism in helicopter controls, especially replicating the elusive magnetic clutch.
Key Features:
Innovative Design: Utilizes a stepper motor (standard Nema 17) for magnetic braking, a parallel actuator, beep trim, and an autopilot drive unit (series actuator).
Realistic Controls: Unlike force-feedback units, this system mirrors true helicopter operations, where control rods/cables are linked to servos, handling astronomical forces without feedback through the controls. Linear force feel units (springs) on a parallel actuator reset the datum point, driven by the stepper motor. This is essential for modern twin-engined rotorcraft that rely on hydraulic servo power.
Bell 212 Cyclic Forces: This simulates the cyclic forces of the Bell 212 with force trim enabled. Many Bell 212 pilots prefer hovering, takeoff, and landing with force trim off for easier control during extended operations like winching.
Adjustable Force Feel: Increase cyclic force by adding stronger springs to the force feel units, providing a customizable resistance feel. The unit precisely replicates Bell 212HP forces.
Comprehensive Package:
Trim release switch beep trim top hat
Cargo release button (connected but not currently used)
ICS/Transmit dual point trigger (not connected)
AFCS release button (connected but not currently used)
Operation Details:
Neutral Positioning: Use the trim release to reposition the cyclic to any neutral position. Upon releasing the button, the cyclic holds its position, enabling a forced feel. Fine-tune the cyclic position with the beep switch top hat for precise control.
Detailed Craftsmanship: Includes a highly detailed Bell 212 cyclic grip. For a smooth finish, a resin printer is recommended. Limited production of grips is available upon request, subject to time constraints.
Compatibility and Ease of Use:
Fits most aircraft grips (both rotary and fixed-wing) with a 25mm fitting.
Simple software integration using Mobiflight and a Leo Bodnar card, ensuring straightforward use across XP, DCS, P3D, and MSFS platforms.
