I second what Steve said. Start using DroneLogBook. The app is good but logging to the website via your browser works a lot better. It will take you a few flights until you get into the swing of things.
I'm currently charging up some batteries and entering in the charge data as I write this.
Don't make a heap of flights then start using it and have to update your backlog of flights this is painful but was a good way for me to really learn how, what & when I should be using DroneLogBook.
Now I log every battery charge, every flight, every time I can't get a GPS lock quickly, every time I lose GPS lock mid flight and I could keep going on.....All this data will really help you start to paint a picture of exactly how your are using Solo.
If you do pursue this hobby and get your commercial licence you will have to do this anyway as part of your reporting for FAA, CAA, CASA etc. So it's good practice to do it anyway.
In regards to the motor replacement the 150hrs stated in the manual seems far to long for these motors. Do some digging around here and you find that motors have been failing as early as 10hrs flight time. The jury is still out as to when they really should be replaced or do they just require the bearings to be replaced. Or as
@RolandS888 and others have now done swap out the stock motors for T-Motors for added reliability.
One day we might actually get the real data out of 3DR as to what average lifespan has been with the stock motors but don't hold your breath.
