Description
Honeycomb Sierra TPM Module brings the tactile charm of classic general aviation straight to your desk, with a lockable metal throttle vernier that feels satisfyingly mechanical in hand and a high-resolution integrated trim wheel that lets you dial in attitude with fingertip finesse. Designed with single-prop aircraft like the Cessna 172 in mind, it combines all-metal construction, integrated flap and parking brake controls, and LED landing gear indicators into a compact module that slots neatly into a serious home cockpit.
What Sets the Honeycomb Sierra TPM Module apart?
-
True General Aviation Vernier Feel The lockable metal throttle vernier with fine-tune prop and mixture knobs doesn’t just look the part—it delivers that push-pull, twist-to-adjust sensation pilots associate with classic GA cockpits. Many users highlight how the incremental adjustment allows smoother power changes during climb and approach, especially in piston aircraft, compared to sliding lever-based throttles that can feel too abrupt for delicate engine management.
-
Integrated Cockpit Workflow Instead of scattering controls across separate panels, the Sierra TPM places trim, flaps, parking brake, and landing gear in one cohesive layout. The low-profile, high-resolution trim wheel earns particular praise for its smooth rotation and granular input, making pitch adjustments during cruise or final approach feel natural. It reduces reliance on keyboard shortcuts and keeps hands where they belong—on dedicated hardware.
-
Solid All-Metal Construction Built with Honeycomb-grade components and a durable all-metal chassis, this module has noticeable heft and rigidity. Enthusiasts frequently mention that it feels planted on the desk, with minimal flex during aggressive throttle movements. Compared to lighter plastic alternatives, the Sierra TPM maintains structural stability over time, which is especially appreciated in permanent or semi-permanent cockpit setups.
-
Seamless Integration with Honeycomb Ecosystem Designed to pair cleanly with Honeycomb yokes and mounting systems, the included dual mounting solution simplifies alignment and positioning. Users who already run Alpha or Bravo units often comment on how the design language and control spacing feel unified, creating a visually coherent and ergonomically consistent flight deck without mismatched modules.

| Primary Ecosystem Pairing |
Honeycomb Alpha and Bravo hardware |
The Sierra TPM Module connects via direct USB, making it straightforward to integrate into most desktop cockpit builds. It pairs especially well with Honeycomb Alpha yokes and Bravo throttle quadrants, sharing the same design philosophy and mounting ecosystem. Thanks to its dual mounting solution, it can be desk-mounted alongside other Honeycomb units for a unified layout. It is not intended for console setups and does not interface directly with standalone hardware without a compatible PC or Mac.
On the software side, it supports Microsoft Flight Simulator 2020 and Microsoft Flight Simulator 2024 through dedicated drivers, and it also works with simulators like X-Plane and Prepar3D on PC. It is not compatible with Xbox consoles, as it relies on standard USB PC/Mac drivers rather than console-certified firmware. For desktop sim pilots focused on general aviation, it slots cleanly into modern PC-based sim platforms.
