What this quad is
The Z25 Pro Analog is BOOMFPV（炸机大叔）'s ducted FPV quad. This page covers the analog camera and analog VTX setup, and walks through the frame layout, the parts used, and routine maintenance.
This page covers the Z25 Pro Analog version. The color photos show how the quad looks; confirm the version and packing list when you order.
The core setup
Power: four 1505 3810KV brushless motors with Gemfan D63 propellers.
Flight controller: FLOW AIO45. The manufacturer's data lists an AT32F435 MCU, an ICM-42688P gyro, built-in ELRS 2.4G, Bluetooth configuration, and analog OSD. The mounting pattern is 25.5 × 25.5mm (M2). These figures are for the flight-controller board, not the whole aircraft.
Camera: CADDX Ratel 2 analog camera. The manufacturer's specs include a 1/1.8 inch sensor, 1200TVL, Super WDR, PAL / NTSC and 4:3 / 16:9 switching, and a 19 × 19mm camera body.
VTX: Z600 600mW analog VTX. Per provided data, the maximum is 600mW, with four levels at 25 / 100 / 200 / 600mW, 48CH, SmartAudio, and button configuration. The front and rear antenna layout is shown in the photos.
Frame and materials
The aircraft uses a carbon-plate frame, surrounding ducts, 7075 aluminum standoffs, Taiwan Fangsheng screws, an AMASS power connector, solid capacitors, and TPU printed parts. The battery strap, camera mount, and protective parts are shown in the photos.
The front ELRS antenna is for radio reception; the rear lollipop antenna is for the VTX. They are placed apart. Separate placement does not mean there will be no interference in every environment. Confirm bind, antenna installation, and link status before you fly.
What this page can confirm is on the aircraft
What this page can confirm is on the build: the ducts and carbon-plate frame, four 1505 3810KV brushless motors, Gemfan D63 propellers, a FLOW AIO45 flight controller, a CADDX Ratel 2 camera, a Z600 analog VTX, a front ELRS antenna, a rear VTX antenna, and the connections and hardware shown in the photos.
This is a description of the aircraft, not a list of extra included accessories. Whether a battery, radio, FPV goggles, charger, spares, or tools are included is determined by the packing list confirmed when you order.
Who it's for
A first FPV quad for new pilots. It is meant to be stable, easy to fly, crash-tolerant, and straightforward to repair. The ducts give new pilots more confidence while they practice.
Check these before you fly
The 3–6S LiPo range shown in the photos is the FLOW AIO45 flight-controller rating. It is not, by itself, the battery range for this aircraft. This quad uses a 4S battery (XT30 connector). 650–850mAh is recommended. See the “Choosing a battery” image above.
Check the screws, propellers, antennas, and power connections. Remove the props before you configure or service the quad. Confirm motor direction, failsafe, and arming settings. Set the VTX frequency and power to match local rules and where you fly, install the antenna, and keep the VTX able to shed heat. The ducts do not make the aircraft safe to touch in flight, and they do not make it crash-proof.
