I'm having an oil canning effect aft of the bagage compartment. looks like I need to add a shim to the bottom of the bulkhead to take up some space. looks like up to .063" I don't know what else to do. So I'll make up some shims and drill to the skin and bulk head. Additionally the Transponder using the Dynon Avionics unit can be mounted any where and I'm thinking of mounting it aft of the baggage bulk head and place the antenna on the centerline of the aircraft between F808 and F809. Which will require a support stiffner for both the transponder and the antenna mount.
