Call that "adverse yaw" and everyone will be impressed. I am surprised the Nexstar does that. Must have insufficient dihedral or something?? There are a few older models notorious for the tendency to "Dutch roll" and roll opposite to your rudder input/intention (like the originlal flat wing Contender 60 with a neutral C.G on a low tank). Bank with the ailerons. Point the nose with the rudder.

12 mph is a typical day at our field. You'll find that some models don't much even notice that much wind except it makes take-offs easier and landings slower. My SK-50 landed better in 15 mph winds than still air. Most symmetrical airfoils like a bit of wind. It's the flat-bottomed ones that suffer in wind and especially gusty winds.

Crosswinds - they can be tricky for anyone . . . especially if they are changeable or gusty. Crabbing in an approach is a delight and a thing of beauty as long as the sidewind is steady.
