Ground-Adjustable Pitch · 16" – 80"

Ground Adjustable

One propeller. Every mission profile.

Ground-adjustable pitch propellers — set the blade angle on the ground, lock it, and fly a fixed-pitch prop optimized for the day's mission. Flexible on the ground, precise in the air.

Blade-angle adjustment at the hub — optimize per mission, no re-prop

The mechanism

Set the pitch on the ground. Lock it. Fly.

1. Loosen the hub clamp

The precision metal hub opens with standard tools in the field. No disassembly of the powertrain.

2. Set the blade angle

Each blade root carries a machined degree scale. Dial both blades to the same mark for the day's payload and altitude.

3. Torque and fly

Lock the clamp to spec and fly a true fixed-pitch propeller. Optimized on the ground, precise in the air.
