Indicated airspeed and wind
In full-scale, unless you're doing say turns around a point on the ground, you will as you've experienced be able to do 360s at constant attitudes.. etc in a wind.
A model in flight IS referenced to the ground. Namely you!
The legendary "downwind turn" situation is a direct result of having to consider the wind effect relative to placing the plane in the air as seen from the fixed point on the ground.
Left to its own, as a free flight would be, a model is as free of wind influenced manuvers as a full-scale.
