model for fly, help please!!!

[loboblanko]

Hello, I have a problem, I have added a flying vehicle to the V15 Ketchup version, I have configured the MDldyna.inc, defineitem.h, propitem.txt and propitem.txt.txt, I have placed the respective textures and models in the client folders and resources, the icon in the client, loads everything, but when I set the object, (it is an elephant that flies with its ears) the worldserver closes as soon as it loads. that may be failing or missing, I hope for your help, thank you very much.

I attach images of the model and some configurations, I have been able to add wings but not that type of vehicle, I am considering it as a "stick" that is, sitting when flying.
