This install mount is designed specifically for DJI S1000, and has extra holes to match with many other airframes. The mount is compatible with X55-CF and X68-CF parachute launchers.
No drilling is required to attach the mounting plate to DJI S1000. For other airframes, the mount has multiple pre-drilled holes. If the holes do not match with your airframe, the mounting plate can be used as a template for drilling matching holes.
