Overview:
The Sub250 DollyFly25 V2 is a compact 2.5-inch cinewhoop designed for smooth, controlled cinematic flying while maintaining enough power for outdoor use. Built on a revised, upgraded platform designed to fit the DJI O4 Pro with a ducted frame design and 4S power system. This Cinewhoop offers a balance of durability, stability and responsive performance suited to cinematic FPV flights.
The frame has been redesigned for improved strength and resistance to shield both the props and onboard electronics during flight. A four-point vibration-damping system is built into the camera mounting structure, helping to reduce jello effects and produce smoother footage directly from the drone.
All versions include a SUB250 M10 GPS module, enabling Betaflight Rescue Mode plus added positional awareness during flight. This makes the platform not only suitable for cinematic work but also provides greater confidence for the pilot when flying outdoors at a distance.
There are two main configurations available, allowing you to choose based on your existing FPV gear:
- O4 Pro GPS version: Supplied with the DJI O4 Air Unit Pro, offering high-definition digital video transmission and onboard recording up to 4K/120, ideal for capturing cinematic HD footage.
- WTFPV GPS version: Delivered without a video system, designed for pilots who want to install their own O4 Pro or VTX of their choice while keeping the same core platform and performance.
This Cinewhoop would make a great choice for pilots who want to record epic footage via the excellent DJI O4 Pro whilst exploring open landscapes- either diving through forests or swooping across dramatic landscapes, this drone fits the bill.
