A:AnswerYes to both questions. One controller can control up to 6 drones at the same time. Also you can have several (we had 5) flying around the same room at a time, each controlled by a different controller. It is also very easy to switch which controller is controlling which drone.
A:AnswerVery easy to assemble. The transmitter requires 4 AA batteries. You will need a small phillips screwdriver to remove the door on the transmitter where the batteries go. After you charge the drone rechargeable battery with the included charge cable, it is easy to attach and slide into the drone. That's it. Happy flying!
