Traditional Helicopter – Mounting the Autopilot to the Frame

On larger helicopters of approximately 550-class or larger the APM, Pixhawk or Cube has been mounted in various locations such as on the FBL unit tray, on top of the tail drive case, or even on the side of the frame (very popular).

Below is a possible method to mount a full-size autopilot on a smaller sized helicopter. The Pixracer is popular on smaller frames that have less mounting options.

  • Separate the helicopter’s main body from its landing gear
  • Attach one carbon fibre plate to the body, the other to the landing gear
  • Drill holes in the upper and lower mounting plates so that the plates can be attached with four strong 3cm or 4cm stand-offs
  • Mount the autopilot to the bottom mounting plate using vibration dampening foam (see Vibration Dampening wiki page for ideas on mounting methods to isolate the autopilot from vibrations)
