Starting February 19th, 2016 the FAA is going to require all drones between 0.55 pounds and 55 pounds be registered to operate in the US. The registration process can be done online starting December 21, 2015. For the first 30 days the registration fee will be waived, but after that it will cost $5 to register your drone for operation. Civil penalties for improper drone operation include a fine of up to $27,500 and criminal penalties will exist with up to three years in jail and fines of up to $250,000. You must be 13 years of age to register via the online site.
Just a heads up for our US customers.
