In the manual, the CoG was recommended at 7cm from LE, at that setting, the plane appeared tail heavy when the throttle is below 60% and drops/sink rate is quite fast but flat. It does not glide very well off throttle.
Does this indicate a CoG that is too far aft?
Have tried moving the CoG as far as 1.5cm forward. At this setting, the plane glides and it appears to fly just like a normal plane should. Would this be a good setting for 3D? Being a balsa/ply plane, I am being very careful as it is not as crash resistant as an EPP plane
