I would go with lack of dihedral for a start..

Also your wing tips may have the equivalent of washin, because of the radiused leading edge. Allowing the tips to stall before the center section. Washout is required.

The wing looks quite flexible, so any dynamic twist in flight during a turn could exaggerate things. Are those rubber bands ?, used for stiffening ?.

The vertical stab area, (fin), is also quite small and could do with being twice the area shown.
