I fly commercially Part 107 the cost of the annual policy through Travers Aviation is $663.00 p/year it includes.
$ 1,000,000.00 in Liability / Property Damage
$ 5,000.00 Medical ( should you nick someone with a prop )
Replacement Cost for my P3P including camera ( which is considered payload )
I can swap out the drone at anytime ( takes 24 hours ) but you can only have 1 drone under the policy at any given time, therefore opted for the Mavic thru State Farm
$1,200.00 to replace the drone $ 63.00 p/year ( End up with an extra controller should a loss occur )
