Hello Francis and welcome to the FOA forums. You might have noticed that the forums look kinda dead at the moment, but don't let that discourage you.
Most of us are lurkers by nature you see
In any case there is a lot to see if you know where to look. Try taking a peek here http://www.forceofarms.com/files/foa_mech_system.pdf
it's the Mech Construction guide. it's got a lot of info about what components are necessary to make a mech.
Unfortunatly the dev's can't fill in the majority of the numbers/stats due to the fact that someone might steal their ideas.
Other than that i'm certain a few comments regarding the mechs and other creations is quite welcome indeed. Feel free to ask whatever comes to mind.
