I am working on a Wildman Blackhawk 38. My first fiberglass build - nice material to work with. Since this is a min diameter, I would like to keep protrusions to a minimum for aerodynamic performance. Instead of screws/nuts or removable rivets to hold the av-bay to the airframe (both of which have a head on them), I am considering set screws which can be screwed flush to the airframe. These screws only need to resist shear loads, so the lack of a clamp force should be OK?
To test the set screws, I drilled and tapped 8-32 threads to hold the nose cone. Seems fine to me and can work on av-bays also. The hex head can be covered with clay or tape to make smooth. Any body else use set screws?
