Replacement Arm for Martian-II Reptile 220mm Quadcopter Frame

Drone arms take the brunt of most crashes, which is exactly why frames with detachable, individually replaceable arms last so much longer in regular use than frames with a one-piece body. This replacement arm is built specifically for the Martian-II Reptile 220mm quadcopter frame, matching the original arm's design so it drops into the existing frame without needing to source an entirely new set or rebuild the whole quad after a hard landing.

Construction is carbon fiber, chosen for its strength-to-weight ratio, at 4mm thickness, matching the original arm's rigidity so flight characteristics stay consistent after a repair rather than introducing extra flex at the newly replaced point. The listing describes it as lightweight and easy to assemble, meaning a damaged arm can typically be swapped in the field or at home with basic tools rather than needing a specialist repair.

The supplier also stocks a broader range of replacement arms spanning from 100mm mini-copter sizes up to 550mm for heavy-duty hexacopter and octocopter frames, so builders running other frame sizes in the same family have a matched source for whichever specific arm needs replacing.

Anyone running a Martian-II Reptile 220mm frame who has cracked or snapped an arm in a crash will find this a straightforward, correctly matched repair part, letting the rest of the build (motors, ESCs, flight controller) go right back into service without replacement.
