I have tried to duplicate your problems/issues. I am not seeing any of the issues you are experiencing with the model breaking apart or panels not rising with the rest of the jet. Maybe you can make a video of the problems and send it to me. I only fly solo, so I am not familiar with adding in other aircraft or multiplayer. I know that some planes can have conflicts when flying in multiplayer because they share similar codes when activating controls.
I will look into possibly creating a "hide landing gear" feature which retracts landing gear visually, even though landing gear is still down for contact points on ground.
