I would strongly suggest that you invest in the Solex app. You will be able to bring up to date with the latest Arducopter version of software for Solo, even if using the stock Cube with ESC issues, to maximize potential and the app is continually being updated to bring online new abilities and features. I've had the app since the beginning and am blown away by Kelly's improvements to the app and Solo's functions during the last few years. Simply amazing.
