WHY can't you see that DESIGN should result in a most-stable dom.! WHY can't you see that locating the mass of several servos aft-of the cg, and outboard, results a less-stable dom.! the cg should be located at thirty percent of mac. so, identify the mac and project a line at thirty percent to the wing root.!!! the c-m should be located (in the fuselage) slightly forward-of the cg line; at a point that aligns with twenty-five percent of mac. when you know where the cg/c-m Should be located, to the extent practical, 'arrange' mass concentrated in that zone. think of the dom of the entire model as a horizontally oriented teardrop 'shape'. see the Deliberate use of an elongated teardrop shape, in the fuselage of a typical ga lightplane. obviously, the application of these design rules to a delta/highly-swept wing requires some 'finesse'. you may know that, as a result of design constraints, the cg and c-m are 'nearly coincident' in some jet fighters. in that case, the aircraft will be susceptible unrecoverable flat spins. it is not known whether your model has this issue. googletranslate

btw, the use of CF rod/tube in an application where it will be subjected to torque is not recommended.

thank you. I will take note.
