inserting model into lomac - a hot air balloon

[Allochtoon]

For refreshing my modelings skills i made a hot air balloon for testing purposes (see attachment), now i want to import it into the game, it's already a .lom file. I saw some people making some static objects which were added to the game instead of replacing objects, how can i accomplish that with this balloon?

 

Also, how do i make a collison box?

 

Thanks in advance.

So i replaced the helicopter SH60B with the balloon, i still have the collision box problem, i assume this is manageable with a certain bounding box option?
