I installed this little jewel yesterday with all the available liveries. Beautiful airplane. The problem is, This airplane is almost totally uncontrollable, It won't climb properly, it won't descend, there are no flaps. The speed will not retard, and it certainly won't hook on to an ILS approach glide slope. The localizer is only so-so as well.. I'm just wondering.. Do I have a lemon here or is there something else I can do???
