The VIFLY Beacon is a tiny, self-powered buzzer that provides a loud audible alarm and flashing LED for drone recovery, with a long-lasting integrated battery and easy adhesive mounting.

Master Airscrew SUPER STEALTH propellers for the DJI Mini 3 Pro/4 Pro deliver up to 37% noise reduction and a modest 2% flight-time boost (about one extra minute). Constructed from glass-fiber composite with a glossy finish, they are US-made but limited to newer Mini models and lack a screwdriver.
