Sub250 DollyFly25 Frame Kit

The Sub250 DollyFly25 is a 120 mm wheelbase cinewhoop frame kit engineered specifically for sub-250 g cinematic FPV builds and close-proximity filming. Combining injection-molded polycarbonate propeller guards with rigid carbon fiber plates, it delivers superior impact protection during tight indoor flight while keeping your total takeoff weight comfortably below the regulatory 250 g threshold.

Key features

• Injection-molded prop guards: High-impact polycarbonate ducts fully enclose 2.5-inch propellers, protecting both the drone and surrounding subjects during close-quarters cinematic shots.
• 20 mm camera mount: Designed around a 20 mm camera, including the DJI O3 Air Unit camera.
• Whoop-style electronics mounting: Takes 25.5x25.5 mm whoop/AIO flight controllers and VTX boards.
• Dedicated vibration isolation: Specialized camera dampeners isolate high-frequency motor resonance and reduce rolling-shutter jello in high-definition video recordings.
