Details

Meet the DollyFly25 V2—an agile 2.5-inch 4S CineWhoop platform built for smooth, protected close-proximity filming.

A practical layout keeps essentials accessible, with a dedicated GPS mount, a top Type‑C tuning port, and improved airflow for cooling.

The DJI O4 Air Unit Pro version is designed for high-quality recording and reliable HD transmission in a compact cinewhoop body.

A four-point damping suspension helps cut vibration and jello for steadier video, especially during fast direction changes.

Integrated COB light-strip support adds bright accent lighting for creative looks (LED strip requires self-installation).

Fast maintenance design lets the protective frame come off with six screws, making repairs and part swaps quicker.

A lightweight PNP build can stay under common sub-250g takeoff targets with an appropriate battery choice (battery not included).

The Redfox A3 45A 32-bit AIO paired with 1404 4500KV motors delivers a balanced 4S power setup for cinewhoop flights.
