Product Description

The GEPRC MARK5 O4 Pro DC is the specialized "DeadCat" version of the legendary Mark5. It takes the most popular freestyle frame of the last few years and optimizes it specifically for the DJI O4 Pro system, ensuring a clean, high-definition cinematic experience without the traditional "freestyle" frame compromises.

DeadCat (DC) Geometry: The "DC" in the name stands for DeadCat. By widening the front arms, GEPRC has ensured that your 4K video remains completely free of propellers, even at the widest 155° FOV settings of the O4 Pro.
Shock-Absorbing Camera Mount: The camera is housed in a CNC-machined aluminum alloy side plate that features independent vibration damping. This "soft-mount" system isolates the O4 Pro sensor from high-frequency motor vibrations, resulting in rock-solid footage and better Gyroflow data.
Enhanced Cooling System: The frame includes a dedicated airflow channel for the O4 Air Unit. This prevents the VTX from overheating during long waits on the flight line or during aggressive flights in hot climates, ensuring peak transmission power at all times.
The MARK5 Heritage: It retains the signature structural strength that made the Mark5 a legend. With 5mm arms and a multi-plate bracing system, it is designed to survive heavy "bando" crashes while keeping the delicate digital electronics safe inside the carbon "cage."

The Pilot's Reality Check:

Weight vs. Agility: Like most DeadCat frames, the Mark5 O4 Pro DC is slightly heavier than its "True-X" racing siblings. It feels extremely stable and "on rails" for cinematic shots, but might feel a tiny bit less "snappy" in technical racing gates.
Firmware Note: Ensure you are running the latest GEPRC custom CLI if you plan on updating Betaflight, as the motor mapping for DeadCat frames is specific to ensure the drone levels correctly.

🤔 Frequently Asked Questions

What’s the difference between this and the "Wide X" version of the Mark5?
The "DC" (DeadCat) version has its front arms swept back so the propellers stay completely out of your camera’s view. The "Wide X" version has a more symmetrical feel, which is better for "pure" freestyle balance (like backflips and spins), but you will see the props in your 4K footage. For cinematic work, the DC is the "asjalik" choice.
Can I tune this drone without plugging it into a computer?
Yes, and it’s a lifesaver in the field. This drone uses the TAKER F722 BT stack, which has built-in Bluetooth. You can use the SpeedyBee app on your phone to change your PID tunes, rates, or VTX settings right at the flying spot without needing a laptop or a USB cable.
Is the O4 camera protected? It looks like it sticks out a bit.
The Mark5 is famous for its 7075 aluminum alloy camera cage. Unlike most drones that use carbon fiber plates to hold the camera, this aluminum "exoskeleton" is incredibly tough. It also features a new silicone damping system specifically for the O4 Pro camera to prevent high-frequency vibrations from ruining your video.
How does the weight affect flight performance compared to the Vapor-D5?
The Mark5 is a bit of a "heavyweight" (around 433g without a battery). It has more inertia, which is actually a good thing for cinematic flights—it "carries its weight" through the air, making your movements look smoother and more deliberate. However, if you want snappy, lightning-fast racing maneuvers, you might feel that extra weight compared to a stripped-down racer.
I see there's a "WTFPV" version—what does that mean?
"WTFPV" (With-Out FPV) means the drone is sold as a "Bind-and-Fly" but without the DJI O4 Air Unit pre-installed. It has all the motors, the stack, and the frame, but you have to provide your own O4 unit. If you want it ready to fly out of the box, make sure you select the full O4 Pro version.
