I think my CG is good for right now. I have it set where the book recommends. My batteries are just behind the two rear servos. I had it setup fairly good on the ground and it only needed a few clicks of the trim once I got it up. I think it was just the wind getting to me. One of the guys I fly with brought out a kite buggy which is a big kite and then a buggy with three wheels and it was pulling him around the field.

Let me know how you like yours with the .36 I think I might consider running a smaller engine to save some weight. Right now my vertical performance is incredible but it still might perform better in other areas with the lighter smaller engine.
