Landing Gear For SK480 F450 F550 Quadrocopter

Prototyping and Engineering Tips from Robogears

• Gimbal Protection: CRITICAL: If you are using a 3-axis gimbal, measure the total height of the gimbal including the camera. This landing gear provides roughly 15-18cm of clearance. Ensure your camera lens has at least a 2cm "buffer" from the ground to prevent dust or pebbles from scratching the optics during motor initialization.

• Vibration Dampening: For heavy-lift F550 builds, you can add small strips of adhesive-backed Silicon Foam or rubber to the bottom of the "feet." This further reduces the "bounce" during landing and helps prevent the drone from sliding on smooth surfaces like tiles or asphalt.

• Weight Distribution: Adding high landing gear shifts the "Center of Gravity" (CoG) slightly lower. This can actually improve flight stability in hovering, but if you mount a heavy battery at the very bottom, ensure your PID settings in Mission Planner or Betaflight are adjusted to account for the new "Pendulum Effect."

• Mounting Security: Use a small drop of Blue Threadlocker on the mounting screws. The high-frequency vibrations from 10-inch propellers can eventually vibrate these screws loose, causing a leg to dangle mid-flight.

• Compass Interference: Since these are plastic, they do not interfere with the internal or external GPS compass. However, avoid running high-current ESC wires directly alongside the legs if you plan to mount a magnetometer near the base.

Package Includes

• 4 x High Landing Gear Legs (White)

• Mounting Hardware (Screws)

Disclaimer: Always check for cracks or stress fractures in the plastic after a crash. A compromised landing leg can collapse during the next landing, causing the drone to tip over and damage the propellers. Ensure all screws are tight but do not over-torque, as this may crack the plastic mounting flange. Not recommended for drones with an All-Up-Weight (AUW) exceeding 3kg.
