Safety
Propellers must NEVER be installed on the drone while you are building or setting it up.
I general rule is that when building or with a battery connected you should never have propellers attached.
A good guideline is:
If propellers are attached - DO NOT connect a battery.
If the battery is attache, DO NOT install the propellers
