7 Reasons to Choose the Explorer LR 4 V2
Why the Explorer LR 4 V2 Stands Out
The main V2 update is the redesigned DJI O4 Pro camera damping system. The rest of the platform carries forward the proven long-range design of the Explorer LR 4.
01 — V2 Camera Damping Upgrade
The V2 camera mount uses four custom damping balls around the DJI O4 Pro camera to better isolate vibration from the frame.
This helps reduce unwanted camera shake while maintaining the lightweight design that makes the Explorer LR 4 ideal for long-range cruising.
02 — DJI O4 Pro Video System
Built around the DJI O4 Pro Air Unit, the Explorer LR 4 V2 delivers a modern digital FPV experience with high-quality onboard recording and a clean HD video feed.
03 — Sub-250g Long-Range Setup
At approximately 179g without a battery, the Explorer LR 4 V2 can remain around 246g when paired with the recommended FLYWOO 4S 750mAh battery.
You get a capable 4-inch long-range platform without the weight of a traditional 5-inch setup.
04 — Built for Efficient Cruising
The Explorer LR platform is designed around efficiency rather than maximum raw power.
Its lightweight 4-inch configuration allows for smooth cruising and extended flight times, with up to approximately 28 minutes of cruising time depending on battery, flying conditions, payload, and flight style.
05 — GOKU F722 MINI 45A Stack
The GOKU F722 MINI 45A Stack provides a compact and reliable electronics platform designed specifically for lightweight FPV builds.
It gives the Explorer LR 4 the processing power and ESC capacity needed for stable long-range operation while keeping overall weight low.
06 — GPS for Long-Range Flying
The included GOKU GM10 Mini V3 GPS gives pilots GPS positioning support for long-range flights.
It is especially useful when configuring features such as GPS Rescue and when flying farther away from the takeoff point.
07 — Pre-installed FLYWOO Finder
A FLYWOO Finder comes pre-installed to make locating the drone easier after an unexpected landing or crash.
For a long-range platform that may be flown farther from the pilot, having an independent recovery tool adds an important extra layer of protection.
Designed for Micro Long Range
The Explorer LR 4 V2 is built for pilots who want a lightweight FPV drone focused on:
Instead of carrying a larger 5-inch long-range quad, the Explorer LR 4 gives you a compact platform that is easier to pack, lighter to fly, and optimized for efficient cruising.
