I flew with the CG back 1/2' today and it is much better. The plane will land much more scale like and inverted flight requires very little forward stick to hold level. It snaps nice now also. I have been playing with props for the 120 AX and I am sold on the APC 16.5x5W! Vertical is now great. The Cermark Pitts is moving up on my list really fast. I still need to balance it laterally.
