The BOM inspection panel mount is an over-dimensioned aluminium plate that you can trim to any size or shape to work on your aircraft.  Simply remove an existing inspection hole cover on the bottom of your wing, cut this one to the exact same size and install in it’s place.

Your BOM will mount directly to this plate using the 2 x standard AN3 bolt with washers and nuts that are included with your BOM purchase.

The angle of the BOM can be easily set to within +/- 20 degrees by setting the angle on the slotted mounting hole and tightening the nut.
