TXservo
 

Although the TXservo is not an RC simulator, it is a sevo test gizmo so I thougth this would be a good place to put this.

The device, yes it's call TXservo, is an electronic device that connects to a PC USB port and comes with software to control it.

After loading the appropriate drivers, and plugging it in to the USB port, and connecting a pair of Airtronics 94322Z servo's, I ran it through a few simple tests. The gizmo will run the servo's through all sorts of servo exercises, and will center the servo.

One thing that is pretty neat about it is that you can put servo's in the plane, hook them up to the control surface, then hook the servo up to the TXservo and load up the software. It will show you centering graphs, and so on. I ran it through all directions of movement and it worked out pretty well.

By the way, it's one of the RCU advertizers. A good product, in my opinion, and reasonably priced to boot.
