  1. Edges of frame pieces should be sanded to avoid wear in wiring
  2. Camera has been mounted with rubber O-rings due to lack of better mount
  3. Receiver antenna has been reinforced with a cable tie + heat shrink
  4. Don't attempt to flash the ESC firmware, 1 of 4 is likely to fail if done via FC, however changing settings is ok
  5. The original camera wasn't too bad in adjusting to illumination changes but lacked dynamic range when flying towards a low sun
  6. Remove the microphone from the camera, you don't need it
  7. Replace nylon standoffs with aluminium standoffs for extra durability
    • The provided M2 screws are however good and long enough
  8. Older Kingkong 1935 props have a much tighter center hole which may not always fit the motors and push the shaft out of the motor instead when the prop is inserted
    • More recent Kingkong 1935 props fix this issue with a slightly larger center hole, those can be identified from the center hub which isn't any longer fully flat
  9. RunCam Micro Swift 2 will not fit with the default standoffs with the included mount
    • With some plastic removal, it's possible to fit the camera using a custom mount while still using the default standoffs and having possibility to get some angle to the camera
    • Only the height is a restricting factor
  10. FrSky XM replaced with FrSky XM+ due to random poor range issues


  • Don't mix V1 and V2 FC and ESC board, the connecting wires have different outputs
    • V2 is much less messy to use and it doesn't require a separate battery wiring to FC
  • The battery wires are on the bottom of the ESC board so be extra careful not to let plain wires touch the frame
    • Use a piece of electric tape just to be on the safe side
