Gusts and turbulence affect an airplane in flight as you described, no matter what turn you are making. Wind only affects ground speed and track, nothing more. A stall in a turn without proper coordination can result in an incipient spin/spin, but the stall would happen with or without rudder if you get too slow. It doesn't have to be an inherently fast plane, you just need to mind your speed. At that sized wingspan just about any plane can be set up without a rudder some just need a little tweaking.
