Hi Duncan

Thanks for your report.
I adjusted now the CG to 235 mm too, because i built the upper tank direkt above of my former CG of 250 mm. During the first Rolluot to check the functionality we detect, if the tank is full on CG 250 mm and i lift the head for app. 10 cm, the back goes down to the ground because the weight is now behind of the CG.
Unfortunatelly I'm not able to adjust the rudder movement to 65 mm. The maximum movement is app. 35 mm due the limitation on the rudder.
By 35 mm the rudder is closed to the surface on the fin. My Servoarm is 35 mm, do you have a longer servo arm or did you remove some glas by sanding the fin ?

Best regards
Rainer
