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.
• Broad camera compatibility: Includes vibration-damped silicone mounting hardware designed to fit 14 mm nano, 19 mm micro, and 20 mm HD cameras, including direct compatibility with the DJI O3 Air Unit without propellers entering the field of view.
• Versatile electronics mounting: Accommodates both 25.5x25.5 mm whoop/AIO flight controllers and 20x20 mm micro stacks using standard M2 hardware.
• Dedicated vibration isolation: Specialized camera dampeners isolate high-frequency motor resonance and reduce rolling-shutter jello in high-definition video recordings.

For optimal sub-250 g flight performance and flight times, pair the DollyFly25 frame with 1404 or 1504 brushless motors (9x9 mm mounting pattern), a 20A to 35A AIO flight controller, and 2.5-inch 3-blade or 5-blade propellers such as the Gemfan D63.
