If it were me I would go for the 4325-425 then. It is a custom wound kv, and will cost a bit more though. If you wanted to avoid that the 450 would probably be just fine. Some like a 19" prop on this plane, and with the 380 wind you will be turning a 19x10. For me I always felt that the plane had extremely noticeable torque effects with a 19" prop and preferred the 18" size props. The 4325-450 will have you on an 18x8, and that works quite well also. Pretty fast in the air, and still easy to 3d with. What I like about the 425 is the ability to run either a 19" or 18" prop. So you get to try out both and make up your own mind. It's a nice in-between kv that can get you fast and snappy with an 18x10, or really good hole-shot hover pullout power on a 19x8.
