Custom adapter to use gong fuselage on my Armstrong alloy mast. I know Gong masts are really affordable but I really like the Armie mast.
Actually if you wouldnt mind trying to measure another way since yours is stuck. If you put a m6 bolt through the hole and use the inside measurement of the calliper prongs to go between bolt edge and adapter pocket edge. That might be more accurate in your case.
Hey Jacob. FoilGuy has kindly provided me the measurements but I wouldn’t mind a 2nd look because his was stuck in the fuselage which limits your ability to get the claws of the caliper in a good position. I also still need a diameter of that front hole.
