I have no experiance with the fp, but just from the way it works, it is less complicated, and less settings to muck up, so is harder to get wrong ( but not that hard ! ) and cheaper to fix as there are less parts to break.

I just figured i would get cp and learn to fly like an fp ( Radds battery 1 - 10 are for basic or fp ) then after i have done that and are confident with my skills, start changing settings and really start the steep learning curve of inversted flight ( expense lol)
