Before I go further, I have to say, good piloting takes precedence over anything. Regarding your Litchi question, it really depends on how you plan to use your ac. As for me, I have both apps but have been using Litchi more now than GO. As others mentioned, Litchi saves time by planning your missions ahead of time through waypoints. I think this is what most people buy it for. With GO you have to fly to each WP and record first. Controlling the ac while getting the shot you need takes a lot of experience and practice. In my case, I want to save time and would rather plan my mission and let Litchi do the rest. Saves battery usage as well. I do fly on P mode for some easy shots. Can I get out of trouble by flying ATTI? I hope so. Hasn't happened yet but I've been practicing. Right now, I wouldn't be able to get some shots right without Litchi. In the future, with more experience, I'm sure I'll be able to. Since I want to make movies now, I am trusting Litchi. However I always have my finger on that P/A/F button just in case there is trouble. So far so good. If all you want is to fly your ac and just have fun, you don't need Litchi. GO is plenty capable. Save your $30 until you want to make great looking movies.
