I noticed mine the same thing with mine and also when I first maiden mine she would ballon on landing and if I gave her throttle she would climb pretty good so I added washers for a little down and right she tamed down a bit. And I was checking my CG seemed right on. But the washers helped a bunch with the balloning still have a ever so slight pull to the right up my up line but it is only 2 clicks so left it alone she flys great now maybe need to move the CG back just a little as she wing rocks a little on Harriers but then again I am a amatuer at the 3D stuff so it might be me LOL
