I have 5 of those motors but have only been running them 3S. I am always excited to see people setting up new systems. You will definitely be going fast. You may be pushing over 75 amps with that set up WOT (wide open throttle). Do a bench test with an amp meter before you take off to see so you don't loose your ESC and possibly the plane.

We usually use a 9x6 prop on that motor 3S and will have over 60 A. I can't tell you what 4S will do but I hope you have beefed up the linkages and servos too. I stalled servos out on a ballistic Assassin a couple of weeks ago and couldn't pull out of a loop. The plane and radio survived with only a little modification to the shape of the battery but we were lucky. Everything was still working on the ground, the servos were just too small for those kind of forces.
