I just recently came from Quito Ecuador. Flew from Cali Colombia to Transfered in Esmeralda and Went to Quito Ecuador. I did not have any problems with Customs. I took out the propellors and hid the drone in my luggage. Did not get searched. Its legal to bring it. But they have this weird rule. If the drone is more than 500 dollars it must be taxed(there are no good drones below 500). Just put it in your check in luggage and odds are high it will not get searched. I posted my pictures on my instagram: Estebond_ambriz
