I've got a CH Pro Throttle that I have programmed for simple dual-throttle control. The set-up doesn't allow completely independent control, but it works for what I want it to do when flying a dual-engine plane.
The Pro Throttle has a thumb-manipulable two-axis mini-stick (similar to Cougar's). Using CH Control Manager 2.0 (excellent, by the way), I programmed two "virtual" throttles, controlled by the main throttle and the X axis (left and right) on the mini-stick. CH Manager 2.0 is very flexible, allowing you to assign the controllers' physical axes to arbitrary axes of any number of virtual devices, all of which AH recognizes. I think I assigned the virtual throttle axes to the X and Y axes of a controller that doesn't actually exist (i.e., "CH Control Manager Device 2"), while I assigned the other axes of my controlers (Fighterstick and Pro Pedals, in addition to Pro Throttle) to the axes of a second, virtual device (i.e., "CH Control Manger Device 1").
The way it works is that when the mini-stick is centered, both "virtual" throttles are set to the value of the physical throttle. As the mini-stick is deflected left or right, the left or right virtual throttle is decreased linearly from the value of the physical throttle. Thus, for example, when the physical throttle is full open and the mini-stick is 50% deflected to the right, the left "virtual" throttle will be full open and the right "virtual" throttle will be 50% open. The nice thing about this set-up is that it is entirely intuitive to use. If you want the dual engines to induce yaw to the right, move the mini-stick to the right. If you want to induce yaw to the left, move the mini-stick left.
After programming CH Manager 2, all that is required is to map my "virtual" throttle axes to AH's throttle 1 and throttle 2. Very clean and easy.
