This install mount is designed specifically for DJI F550. Use this mount with the 3.2Kg Parachute Launcher.
No drilling is required to attach the mounting plate to DJI F550. Mount is fixed to the airframe with the same bolts that hold the motor arms, so no drilling is required. The height of the mount can be adjusted to match different landing gear types and it works even with the original very low motor arm "legs". You may be able to adapt this mount for other airframes.
