First of all, love the QAT, I like the format as it's mostly audio, so I can listen while working on the layout, and glance at my phone screen and see the video when something visual comes up.

With ProtoThrottle, the repeatability by notch is easier with a TCS UWT-100. I have mine set up for Pete M's layout, I believe I set the fast inc/dec to 12 speed steps, to match his throttle notches on locomotives set up for ProtoThrottle, and it works great. So basically I can click up and down notch by notch, and then a function for the brake. The only control that I lack is the ability to do a partial brake application like the ProtoThrottle does by pulsing the brake function.

I'm hoping to get a PT of my own soon and start configuring locomotives on my new layout for it.
