Abstract

A hovering remote-control flying craft having a molded frame assembly includes a plurality of arms extending from a center body with an electric motor and corresponding propeller on each arm. In various embodiments, the motor and propeller are mounted downward-facing at a distal portion of each arm with a motor cover over the motor. The center body can be formed of a two-piece molded structure that sandwiches a circuit board to provide structural support for the frame. The circuit board can include a plurality of tabs that facilitate mounting of wire connectors, and can also provide antennas and emitters for both IR and RF communications. In some embodiments, a removable safety ring protects the propellers from lateral contact.

2. The craft of claim 1, wherein the circuit board assembly is positioned and secured in the center body to provide structural support for the top member and the arms of the molded frame assembly.

3. The craft of claim 1, wherein the circuit board assembly includes a printed board having a plurality of tabs that extend outwardly from a central surface structure adapted to support circuit board assembly components, including a gyroscope, an accelerometer, a magnetometer, a microcontroller, and a radio.

4. The craft of claim 3, wherein the plurality of tabs include a tab having a power connector for the rechargeable battery, a tab having a radio frequency antenna for the radio, and a tab having both an infrared emitter and an infrared receiver.

5. The craft of claim 1, further comprising at least one multi-color LED operably connected to the circuit board assembly and configured to display a selectable color in response to frequency signals from the handheld remote control.

6. The craft of claim 1, further comprising a removable safety ring mountable to and extending from the distal portion of the arms and configured to protect the propellers from lateral contact.

7. The craft of claim 1, wherein each of the motor assemblies include a motor cover that is configured to secure the motor to the arm by a snap fit.

8. The craft of claim 1, wherein the arms are formed of an injectable molded plastic having a durometer greater than 70 Shore D and the legs are formed of an injectable molded plastic having a durometer less than 60 Shore D.

9. The craft of claim 1, wherein the center body is formed of a two-piece structure that sandwiches the circuit board assembly to provide structural support for the molded frame assembly.

10. The craft of claim 1, further comprising a removable safety ring that protects the propellers from lateral contact and includes an outer ring supported by a plurality of Y-arms that are each adapted to correspond to and interface with a corresponding one of the at least three arms.

11. The craft of claim 1, wherein at least one of the at least three motor assemblies includes a second propeller operably mounted upwardly-facing, in addition to the at least one propeller operably mounted downwardly-facing.

12. A hovering flying craft system comprising:

a hovering flying craft including;

a frame assembly including a center body having at least three arms extending outwardly from the center body;
