Keith, thank you for Sharing. My ship CG is now 190mm exactly (as suggested by Oxai).
Next week I will take the test flight this way. If needed can move the CG forward by moving the Throttle servo from the inner tray forwards to the Muffler tray or by moving the Batteries which are now placed on a tray under the Canalize opening.
Moving CG backwards can be done by moving the CDI unit backwards. (Now it is placed right behind the Firewall).
I will report after the test flight.
Regards
