Hey
I replaced the neighborhood heli(not the career Heli) with a plane i took from the net.
It was original a airbus A340 but i changed a few things on it.
The engines for instance, made low polygon ones.
The mesh is still pretty high tho, you be warned(dont use this on a crappy comp)
It works perfect in my game altho i haven't test the Lot/career Helicopter yet Lol...
Both helicopters use the same textures but i fixed intigrity on this one so both will work.(I hope

)
Edit: Yes, both work together

Let me know how it performs and i might try to build a Airport one day

Put this in your
Defaults folder in your Sims2 directory!!
Note:
sorry, I thought this was a base game object but unfortunatly you do need Nightlife EP to get the plane working ingame.
