Another addon: a comfy butt pad! 
I downloaded Little Navmap and so far I am very impressed. Very intuitive and I especially like the flight plan elevation profile at the bottom! I also signed up for the bush talk radio and downloaded it but have yet to give it a try. I’ll keep you posted.
I have 16GB RAM. It works fine but I would eventually like to upgrade to 32GB just for peace of mind.
How did you go about planning your sights to see along the way? Did you just fly by interesting looking buildings and look them up on google or did you have a set pathway?
