Because it's a very open question, about a very overused term and misunderstood subject.
The Mystique, like any other aircraft, will stall if flown too slowly or the critical AoA is exceeded. The moderate taper with washout provides appropriate stall progression for this type of model. Occasionally, depending on aircraft attitude and control surface input, you may stall one wing before the other. You will not experience random 'tip stalls' while casually flying.
