I am 99% sure that you can carry more line tension without tip stalling, when ailerons and flaps are in line. Wing just works better. And drag is small compared to large flap camber and small aileron camber scenario - > faster speed.
Maybe (just maybe) having radical camber in tip section can provoke tip stalling. But then again, I do not know any modern F3J plane that has nasty tip stall tendencies. You get plenty of warning (directional unstability) before it really bites.
