I think that should be about right. The superfly is the larger of the "supers" I believe. I use a 1300 3s on my foamy. I love that size pack. great on lots of planes.
I'll bet this thing could fly after a 20 guage shotgun blast, but you might need to do some repairs to it. If it was up close, then just tape over the hole. From farther away, then might need a few smaller pieces of tape for the more numerous smaller holes. I don't know what shotgun proof rx and esc you're going to use though.
