Thanks :-)
Well I just tried it. TX in pupil mode, and it still sends through its ariel. Only (of cause) with all mixers set to zero. The controlsurfaces on my test plane went crazy So that did it; I'm not using my MC4000 for simulator purpose, since I wont be sitting by the PC with the ariel more or less extended, and I deffently will not take the x-tal out. I'll try to buy a pupil-module for my old Futaba F14 instead.
