Im suprised that the only thing that holds the flimsy plastic engine nacelles on is a little epoxy on the inner half of the engine nacelle and one tiny screw on the outside half. Seems like the weakest parts on an otherwise very stout design.
Don't worry about the epoxy joint on the plastic engine nacelles, if you epoxy them from both inner sides, at the entrance of the slot and other end, it will be very strong hold. Plus you can add bit more epoxy on the outside of the pylon slot and fill it with filler to make proper fairing as i did to mine. No need to add screw for outer side!, it will look ugly...
