The conventional wisdom is that rc quads are _more_ susceptible to winds than rc acrobatic helicopters (and have lower max speeds) largely because they usually have a "cupped" shape to their props (to maximize efficient static thrust) which can catch catch a cross wind. In contrast an acrobatic rc heli has perfectly straight/flat blades that change pitch to create lift and are quite "invisible" from the side.

That said, in this design, having two different types of rotors mounted non-symmetrically seems bound to induce some yaw from winds.
