Oh, I spoke to someone at Futaba USA Today. They told me the MC9100A 100A ESC which listed for 219.99 has been discontinued. Its replacement is the MC9130 which is a 130A beast and retails for 359.99. It is not available yet. Who knows wether this ESC will have the same F3A friendly properties as the MC9100? It looks a lot like my big Hobbywing Platinum 160 ESC in my 800 size heli.
