Clears external modules, doesn't block the ports and fits in stock case.
So far holds well glued with epoxy after properly sanding both parts. There is a hole for a cylindrical head M3 screw that could be glued inside the radio case for additional hold (no room inside for a nut) but I don't think it's necessary unless you intend to swing the radio around like mad...
Obviously doesn't balance but given the weight and form of the radio I don't need/want a strap for flying, just to be able to free my hands to carry and manipulate stuff without having to find a place to put the radio down and having it hanging down is perfect for that to get it out of the way.
