Honeycomb Aeronautical's Sierra TPM: A Precision Tool for General Aviation Simulators

Welcome to the Honeycomb Sierra TPM

The Honeycomb Aeronautical Sierra TPM Module stands out as a significant addition to the ecosystem of simulation hardware, especially tailored for general aviation enthusiasts. Its recent release marks the company's dedication to aerospace-focused gear, diverging from their previous offerings, such as the Charlie Rudder Pedals, which failed to captivate the community.

In my hands-on experience with the Sierra TPM, it became clear that this isn't just another accessory; it's a specialized tool designed for serious simmers seeking authenticity in their virtual flying. After months of anticipation, now that the retail version is available, it’s evident that this product revitalizes Honeycomb's reputation for quality aviation controls.

Unboxing and Build Quality

From the moment you unbox the Sierra TPM, the weight and solid build of the device make a strong impression. It weighs in at 2.6kg and boasts an exterior crafted from hardened plastic, while most touchpoints — including levers and mechanisms — are made from metal, promising durability. The packaging is functional, prioritizing practicality over flashiness, but it effectively protects this substantial piece of hardware. Inside, you’ll find the module, a USB-C to USB-A cable, desk clamps, and a quick start guide.

The dimensions are 24.8 × 12.0 × 30.9 cm, and while these measurements don't seem excessive, the module has a presence on the desk that some may find overwhelming. Initially, I struggled to integrate it seamlessly into my setup; however, its design does complement Honeycomb’s Alpha Yoke beautifully, creating a coherent aesthetic.

Effortless Integration

Mounting the Sierra TPM is straightforward, matching the familiar mechanisms of existing Honeycomb products. It utilizes a secure system with two metal clamps to ensure stability, and if you prefer an under-desk setup, the screw pattern remains unchanged, allowing compatibility with previous accessories. This consistency is a boon for those building elaborate cockpits, offering a sense of cohesion among pieces.

Specialization for General Aviation

Designed predominantly for piston aircraft operating with throttle-prop-mixture systems, the Sierra TPM enhances the flying experience for those who frequent general aviation simulators. For instance, Cessna pilots will find that the throttle lever operates smoothly, complemented by friction adjustment to avoid unintended movements. The vernier-style controls for prop and mixture not only replicate real aircraft functionality but also incorporate a push-to-unlock mechanism, significantly enhancing the realism.

The ability to twist knobs for fine adjustments elevates tasks like mixture leaning to a new level of satisfaction, which is often absent in more generic hardware. Each control is intuitively designed, from a trim wheel that allows nuanced adjustments to the flap lever and a tactile parking brake that feels just right. A highlight is the landing gear switch, which features a satisfying spring-loaded action and an LED indicator to confirm operations, adding character to the module's user experience.

Simplified Setup and Compatibility

Setting up the Sierra TPM is user-friendly, with downloadable presets available for leading flight simulators, including Microsoft Flight Simulator 2020 and 2024, as well as X-Plane 11 and 12. The throttle, prop, and mixture controls are mapped effectively, and you have the flexibility to modify settings based on specific aircraft requirements. Unfortunately, it lacks compatibility with Xbox systems, which may limit its appeal to some users.

Performance on Screen

In the simulator, the Sierra TPM consistently delivers premium performance. Each axis operates predictably, with minimal latency. For instance, during a flight in Microsoft Flight Simulator 2024 using the Cessna 185 Skywagon, the controls translated seamlessly into simulated aircraft responses, whether it was throttle adjustments or mixture leaning. Transitioning to the Beechcraft G36 reaffirmed the effectiveness of the landing gear operations, while the trim wheel facilitated smooth cruising stability.

Assessing Value for Different Simmers

However, the key consideration for potential buyers is determining whether the Sierra TPM aligns with their flying preferences. Priced at £199 GBP, its value is most apparent to those dedicated to flying piston-powered general aviation aircraft. If your flights generally involve airliners, business jets, or military aircraft, you might find this device less beneficial. Conversely, for those committed to excellence in piston flight simulation, the Sierra TPM emerges as a standout in the current hardware market, offering substantial tactile satisfaction that broader throttle quadrants can’t match.

Returning to Form

After the underwhelming reception of the Charlie Rudder pedals, the Sierra TPM represents a positive shift for Honeycomb Aeronautical. The design reflects a blend of quality and affordability, and with features like a generous two-year warranty and free shipping, it encapsulates value. Having spent ample time with the module, it’s hard not to appreciate its thoughtful engineering and the delight it brings to the simulation experience.

Ultimately, the Sierra TPM embraces its role distinctly and executes it with impressive precision. It acknowledges its target audience of general aviation enthusiasts and focuses on delivering what they seek without pretension. This clarity of purpose is a significant strength, distinguishing it in a crowded market.
