What is an HD Long Range Ultralight?
This arm belongs to the Shocker HD Ultralight, a new class of FPV drone inspired by “Dave_C_FPV”.2 These “crazy lightweight” frames (under 60g) are combined with digital FPV systems, lightweight motors (like 1805 or 2004), and T-mount props. The result is an incredibly efficient drone that can fly for 10 minutes or more, allowing you to go on long-range adventures in beautiful HD.
Genuine Catalyst Quality
This is the official 4mm replacement part from Catalyst Machineworks. It’s designed for the specific “dead cat” geometry of the Shocker 5″ HD, which uses shorter front arms and longer rear arms to keep the propellers out of the camera’s view. This arm features the M2 12x12mm motor bolt pattern required for the lightweight T-mount motors this frame is designed for.4
