RambO Mosfets

Hello,

I am reverse engineering the RambO board and making it myself. But one thing that continues to confuse me is why there are two types of mosfets being used?? My only guess is to save space of save some cost? I am putting all of the mosfet control on a separate board and I'd like to buy and deal with only one mosfet if at all possible.

Any thoughts?

Thanks!
