The recommended CG range is 100mm - 120mm behind the leading edge at the wing tip. I flew the maiden flight and the first 14 flights with the CG behind the recommended range because the receiver batteries were mounted on the tank tray. I was about halfway through the set up steps at this CG.
The CG range is very forgiving. The plane flew great with the CG well behind the recommended range. It wasn't until I was working on spin entries that I wanted a further forward CG.
With the hardware mounted where you've seen (receiver batteries at the top right of the motor dome) the CG is at 120mm behind the leading edge at the wing tip.
