Thought I should open this; yesterday I started experiencing some pretty horrendous wing flutter across the whole aircraft. It was a first harmonic, so the fuselage went up, both wingtips wend down (and vice versa), bending I would guess around 200mm!
Apart from the normal stuff, I am carrying 2x 7s 4Ah LiPos (about 0.7kg each) and then a payload of 1-2kg. All up weight of the X8 is around 5kg.
I have fiberglass tape on the underside of the wing, from the root to the tip.
Anyone else experienced such extreme flutter?
I've added some more tape & am about to go for a fly. Hopefully this will reduce this resonance.
