sing the specially-designed pen with conductive silver ink in this drone kit, up to 3 students work together to draw circuits on the plastic or cardboard arms. They can also design their own drone arms using the included extra cardboard. Simply assemble the completed arms, then snap the hub and motors into place. Control the drone from up to 150 away via a Wi-Fi connection with an Android or iOS device. The hub also includes a camera to take pictures or record video during flight. A rechargeable battery provides up to 3 minutes of flight time. If the drone crashes, students can simply rebuild it and fly again! Recommended for Elementary and up.
