Don't limit yourself to helos. There are plenty of really cool things you can think up for WinSPMBT, like naval battles (load a landing ship with 120mm guns), gang wars, whatever. Even without making a mod, you could build all kinds of battles. The editor is very powerful, and so is the campaign design feature. WinSPMBT is probably the best game for scenario designers on the market.

Here's another one I just finished. This is a VERY difficult one, and nobody is going to get it right on the first try. Once again, you're an Apache pilot, except this time you have to escort a UH-60 rescue copter.
