Mine dont hold, they Keyhole is loose and the grip is wobbly on the pylons. The area where the bolt mounted on the wing is supposed to slide back into the narrow keyhole part of the pylon is obstructed by white glue in irregular intervals internally in the pylon. I haven't even gotten to the tanks yet. @Alfa did you find a better mounting system? Like something that I can screw down instead of yanking on a pylon to pull it into a narrow keyhole section and hope it holds?

Also the bolts are machine screws but seem to be screwing into hard ply which isnt going to keep its grip and thread long. I would have hoped there would be blind nuts on other side but no there isnt. It's going to hold for 40 flights and then one side will depart after the wear and tear between machine bolt and wood and a drop tank will fly off.

HELP!
