Hi Martyn,
Thank you for writing us back and good to hear that you already received your aircraft,
With regards on your concern, here is the analysis from the repair team, "fly162
t=144.0s h=21.6m the power off in the air so the drone fell down.
conclusion: power off. free of charge" so with this there are no other issue except for a power off from the aircraft.
Thank you for trusting DJI and have a nice day!
Best regards,
So is it fair for me to think I can still use the battery as it was aircraft error and not battery.? Battery was not asked to be sent tin for testing .
