Just when things appeared to be settling down, a new R/C system shows up. The new product is called LocoFi. I've been in touch with them and have had an opportunity to perform a preliminary review. Their first product is designed for HO and they are currently working on a version for S and O scale. They currently have an app only for Android, but are working on an IOS app. What is unique about LocoFi is that it is the first R/C system to employ WiFi exclusively.
