A Collective for Helicopter Simulation: Functional Design, USB Connectivity
Helicopter flight simulation places distinct demands on controls. Unlike fixed-wing aircraft, where a throttle quadrant and joystick handle most operations, rotorcraft require a collective lever — a dedicated vertical-axis control that manages blade pitch and, in many cases, engine power.
The Hoowalt Helicopter Collective with Throttle Axis is a USB peripheral designed for this purpose. It offers a purpose-built solution for sim pilots who prefer dedicated hardware for helicopter operations.
Mechanical Feel and Twist Throttle
The collective lever moves along a vertical axis with internal damping that provides smooth, controlled travel. This damping is intended to simulate the mechanical resistance found in actual rotorcraft collectives, offering a more predictable feel during fine adjustments.
At the end of the grip is a twist throttle axis, a feature common to many light and medium helicopters. This allows independent management of collective pitch and engine power, maintaining the separation of controls that helicopter pilots expect.
The lever is 427mm in length and mounted on a base measuring 99mm in width, designed to provide a stable platform for regular use.
Controls on the Grip
The control head includes:
-
2 momentary self-centering push buttons
-
2 metal toggle switches
These are positioned for access without changing grip. They can be assigned to functions such as communications, lighting, autopilot modes, or other commands within the simulator. The toggle switches are rated for repeated use and offer a positive actuation feel.
Construction and Mounting
The collective is manufactured using 3D-printed PETG material. PETG is chosen for its balance of impact resistance and dimensional stability, making it suitable for a control that receives frequent input.
The base is compatible with standard aluminum extrusion profiles, commonly used in DIY cockpit frames. Once mounted, the unit remains stable during operation. The collective connects to a Windows PC via a single USB cable and is recognized as a standard game controller without requiring additional drivers or third-party utilities.
Compatibility
The collective works with:
-
Microsoft Flight Simulator 2020 / 2024
-
X-Plane 11 / 12
-
DCS World
-
Prepar3D (via standard axis assignment)
No proprietary software is required. Assignment of axes and buttons is performed within each simulator's native controls menu.

Considerations
This collective is a specialized input device. It is not necessary for every simulation setup, but for users who fly helicopters regularly, it offers a more dedicated interface than general-purpose throttles or joysticks.
The product is manufactured using 3D printing and assembled by hand. Surface finish may show minor tooling marks typical of additive manufacturing processes. The design prioritizes function and durability over polished cosmetic appearance.
Final Thoughts
The Hoowalt Helicopter Collective provides a functional, dedicated option for helicopter simulation. Its damping mechanism, twist throttle, and onboard controls are designed to support the specific operational requirements of rotorcraft flying. For sim pilots who prefer dedicated hardware for helicopter operations, this collective offers a practical addition to the cockpit.
