You know Mike I may play around with the CG a little more but when I took the airplane off the first time, I really did not notice that it might hav been tail heavy becuase I did not add any down elevator. I added one click of up. I like the way it flies otherwise, so I have to figure a way out to make it perfrom knife edge. May,be I will try moving the battery forward a bit and see what happens. The only bad thing about this plane is that it does not come with wing adjusters!
