Keep your C of G biased toward the 160 as it will flare better when you come into land, I've sold mine and I am sure it was 165mm with the turbine in the rear and two big Nimh batts in the nose. Don't listen to anyone who says keep it forward, jets don't like forward C of G as my mate just found out with his now rebuilt Phoenix! As I've said previously make sure your brakes are 100% as they do land pretty fast, I ended up using a jetronic valve as this worked faultlessly and uses very little air pressure, I also moved my brakes to the trainer switch so it was easy to get to in a hurry and could not be put on in error.
