I had a similar problem, caused by a couple of controls fighting each other. Go to Options, Settings, Controls. Click where it says Saitek Quadrant and a list of the various units is unfolded. In addition to Saitek Pro Flight Quadant, mine also lists CH Pro Rudder Pedals and CH FLIGHT SIM YOKE USB. Check each one to make sure only the Quadrant is controlling Throttle, Prop and Mixture, or whatever. In my case I found one of the three levers on top of the CH Yoke was also still assigned to the throttle function.
Worse, included in the list are Mouse Yoke and Mouse Look. If they are in your list check that they don't have any lever assignments active.
If you have duplicate assignments then that produces exactly the type of bouncing etc that you describe.

Tried everything, even deleted the registry entries as per Saitek instructions. As far as FSUIPC, I have the registered version, but baulked at trying to set it up. Basically, moving the lever slowly and smoothly, the lever on the screen, and the power output of the aircraft is plain erratic, suddenly jumps to full power, then back to idle, then bounces. And that is when trying to do it slow. Leaving the lever in one position, it sort of settles down, but just touch it, and it is away again. Makes it rather difficult to taxi, and get a smooth approach. Once on cruise, it is a little easier to set the levers to the required settings. I suspect the carbon tracks are knackered, as it is all to easy for dust to collect inside the unit, and you cannot get inside without surgery. It is not my machine or OS or FSX, as plugging in another joystick is no problem at all. I am waiting on Saitek to come back, but they have reorganized/outsourced their response departmentFrank ----- Original Message ----- From: "Fossil" <fossil@xxxxxxx> To: <jhb@xxxxxxxxxxxxx> Sent: Wednesday, April 21, 2010 5:55 PM Subject: [jhb] Re: QuadrantsI presume you've tried a recalibration, both in the Windows control panel and in FSUIPC (if you still run this)? bones bones@xxxxxxx -----Original Message-----From: jhb-bounce@xxxxxxxxxxxxx [mailto:jhb-bounce@xxxxxxxxxxxxx] On BehalfOf Frank Fisher Sent: 21 April 2010 16:44 To: jhb@xxxxxxxxxxxxx Subject: [jhb] Re: QuadrantsMy pedals are plugged direct into the back of the machine. The yoke directinto the front or back. The main controller is plugged into the Yoke, viamini round plug, the secondary, a standard USB plug, either into the frontor back, or the yoke. Would have been better if the main controller had a USB plug as well.Plugging in other joysticks, they are steady as a rock. The fact that it isonly the one lever, which is the most used, which is causing the problem. I do not think the life cycle of those carbon sliders is very high.As I recall, I had no problem with either, before reinstalling Vista a fairwhile ago. Only since then. Perhaps an upgrade to Win7 will do the trick, or not as the case may be. Or perhaps deleting all the Hub devices in the device manager, and let Windows recreate them would help. There is a lot of them.

I thought they were going downhill, a couple of months ago, coincident with the change to W7. Eventually I sorted them out, by a mixture of uninstall followed by reinstall, plus changing the USB Hub into which they were plugged. I think it was the last move that cured them, so it would be worth trying this first. Best bet might be to try plugging one of them directly into a USB socket on the PC, then see how it behaves. The downside of a large number of USB connected addons seems to be unwanted interaction. Occasionally I find that changing something like an ADF frequency can also result in a change in my GF Autopilot's Altitude setting.

It is now in use solely for the buttons which is controlling my AC electrics, Gens/Batt/Starter etc. Now the main throttle is going the same way, unstable and bouncing outputs. These units are just over 2 years old, with reasonable use, mainly for GA and some jets, for Helios, I use a Saitek twiststick. A careful examination inside, reveals the lever controllers, are constructed using open to the atmosphere carbon sliders, instead of the more usual, and more robust, rotary pots. Ok, so the units are smaller for that. I imagine that dust has filtered inside and on to the carbon face, and then wiped by the slider, which has gradually worn off the face, reducing electrical contact. A very poor design. I am now faced with the prospect of replacing said controllers, sooner rather than later than expected. The Yoke and Pedals are A1. Depending on Saiteks response. Replacement controllers. Saitek? Costing? Replacement controllers CH? Costing? Or dig out my soldering iron, and replace the pots with sealed rotary ones. A new housing for the larger pots will be needed of course. Anyone else with Saitek throttle controllers, beware. I got mine from Pixmania, so I am not expecting a good response from Saitek. I am not a happy bunny.
