Drones are continuing to take off as Christmas gifts.
This holiday season, shoppers will buy nearly 1.6 million drones, up 31 percent from last year, according to the Consumer Technology Association.
But on Christmas morning, remember this warning: If they weigh more than 0.55 pounds, the high-flying gadgets have to be registered with the Federal Aviation Administration.
A registrant must attach a drone ID number, linked to the owner's name and address, and pay a $5 fee.
