Thanks for the info! Giving it a try right now.
At 65 years old and an electrical engineer for 40 years, I've always been able to "play" with the latest toys. Having started when computers were just starting - this new tech is mind blowing (and hard to keep up with)!
Well, we have similar minds then! I'm 69, and an Airline Transport Pilot, for both airplanes and helicopters, with lots of hours in sophisticated commercial jet simulators, so flying is not new, but the drone is! If there is a tool out there to make my flying smoother and more professional, I will seek it out. The Litchi app is great, I just wish I could use my DJI Goggles with it! The Goggles work well with DJI Go 4, but then I lose my waypoint capability and precise planning. Of course you can use cheaper goggles, but I made DJI Goggle investment, so would like to use them.
The Litchi Virtual Mission in conjunction with Litchi Hub is the best I've come across for Android users. Very precise, very smooth, and when checked with LVM, is very accurate. I learned a lot about using "Interpolate" and "Focus POI" functions in the hub/app. Always wondered why my camera was not exactly where I wanted it when I flew a planned route. I found I was using "interpolation" too liberally and by switching back to Focus POI, in some cases, the camera ended up where I wanted it to be. I would have had a hard time figuring out that problem without LVM and Google Earth, where I could pre-test various Litchi settings, altitudes, etc., to get what I wanted. May save you from hitting something you can't see as easy from the ground too, like highline wires, towers, etc.
I will be shooting some winter scenes this weekend out of Grand Marais, MN, where I'm staying at a friends house for a few days. Temps are going to be 10-15 F, so we'll see how that goes using the Spark and Litchi for missions that are fairly long. I've operated down to freezing before but nothing as cold as it will be this weekend. Some of our Canadian counterparts do it all the time, so I think I will be fine.
