Got the CG checked.
I went with a XICOY and using the 15.5 cm mark from the LE at the root.
With this, I am at 54 pounds.
and slightly tail heavy.
this can be fixed quite easily by moving the batteries forward. Currently, the batteries are in the back, as well as the tray.
Worse case scenario, is to move that tray forward.
but I will try the batteries 1st.
15.5 cm aft of the LE at the root. The CG point.
