I tried adding the Allied Precision bomber, as a buildable unit. I build the mod with no problems go to build the unit and when it completes the game crashes saying it is too big. Any ideas? Thanks a lot.

That's a new one. Could you post a screenshot of the error message?

try this

It says "object position too large", which makes me think that the unit is not being properly positioned, not that it's too big.
