RPI memory card replacement

I did make small mistake at the beginning of my journey with Pixhawk and it was related memory card.
8GB memory card is too small to handle drone software. After installation a few new applications memory card was completely full and out of space . It happened for me yesterday when I was trying to add Youtube streamer. Finally I lost 2 days for system installation and configuration same way as it was done before.
A new, fresh RPI installation looks much better for me and works very well with Pixhawk. 
Seems, a new 16GB memory card will be useful for me for a long time.
