flight sim could be better

I have had the product for quite some time over one year. The device worked well (sort of) when i was flying around on my plasma screen. I had it hooked up to x-plane and with a g5 mac and a 42" plasma screen. Overall i was fairly content with it, then again my flying was pretty marginal, holding heading a altitude. The unit had been sitting at the airport hangar for about 5 months now, so i decided to dust it off and hook it up to my Intel MacBook Pro/2GB ram/ 7200rpm drive, etc. X-plane is running the newest release 8.5. I am pretty unimpressed with the yoke, since the clamps don't really hold it secure to the table, it starts to come off the table when you start to land (while flaring) and forget about holding heading or altitude unless you configure the buttons to autopilot alt. or hdg. one button for autopilot discon. The whole yoke seemed to lack any precision and the only way to fly the sim was to put the plane in auto pilot. X-plane is a little too realistic in some sense, when adding 10degs of flaps, first notch (C172) you get the typicall ballooning, you push the nose down (of the airplane) and the kiss the TAS good bye and Alt. Getting the plane to descend at a constant rate was also a joke with the yoke. The best way to do it was add 10 deg. of flap auto pilot for alt. and pull power. You get about 300ft descent, which doesn't do much good... Part of the problem with the yoke is that is cheap and there is no detent for the neutral position, like there would be for a joystick. Just to compare the yoke i went out and bought the logitech joystick and it proved to work better. But was too much work to keep it steady for landing on the centerline in a full power off stall condition or close to Vso.
