I have experience with making custom plane models in 3ds max and importing them into Realflight. Recently I have been working on custom drones, but they don't seem to work correctly. They will import just fine and will be visible in the aircraft selector, but once I select it Realflight will crash. has anyone else had this problem? I followed the naming instructions I found in the forums. I tested the model import and it would import and be selectable when I told the model it was a plane. It didn't crash when I did this, but I want to import it correctly as a drone. thanks for your help
