Quick Answer
The GEPRC Cinebot35 O4 Pro is a 3.5-inch ducted cinewhoop weighing 391g without battery, powered by SPEEDX2 2105.5 2450KV motors on a 60A AM32 ESC with a TAKER H743 flight controller. It carries a full DJI O4 Pro Air Unit for 4K recording, includes GPS with rescue mode, and hits 140 to 150 km/h. It is the most powerful cinewhoop we stock, built for outdoor cinematic flying with GoPro-class payload capacity.
The Most Powerful Cinewhoop in Our Workshop
The Cinebot35 O4 Pro is a different animal from anything else in our cinewhoop range. At 391g dry with a 167mm wheelbase, it sits between a Cinelog35 and a full 5-inch freestyle quad.
The powertrain is the headline: SPEEDX2 2105.5 motors at 2450KV on HQ ducted props, fed by an H60 60A ESC running AM32 firmware. On a 6S 1100mAh pack the all-up weight is 583g, and it still punches out harder than some 5-inch builds we have tested. Oscar Liang measured 140 to 150 km/h top speed, remarkable for a ducted quad.
GEPRC ships two PID profiles: Profile 1 for cinematic, Profile 2 for aggressive freestyle. The stock tune is genuinely good, with minimal prop wash for a ducted frame.
O4 Pro, GPS, and a Modular Camera Cage
The Cinebot35 ships with the DJI O4 Pro Air Unit pre-installed, giving you native 4K recording at 100fps without needing to strap on a GoPro. For pilots who do want an external camera, a GoPro mount is included in the box. The modular camera cage is shared with the Cinebot25 V2, so you can swap the O4 Pro unit between quads.
GPS is a GEP-M10Q module with satellite lock in about 80 seconds and roughly 25 satellites tracked. GPS Rescue mode is pre-configured, meaning if you lose signal the quad flies home. For a BNF that customers charge and fly the same day, this matters more than most realise.
Cinebot35 vs Cinelog35: Ducts Make the Difference
Both are 3.5-inch GEPRC cinewhoops, and customers ask which to buy every week. The Cinelog35 V3 uses prop guards at roughly 300g dry. It is quieter and better suited to tight indoor spaces. The Cinebot35 uses full ducts generating more lift and stability, but the trade-off is noise. Oscar Liang called it possibly louder than his 5-inch freestyle quad. The Cinebot35 is an outdoor rig.
If your work is indoor real estate tours, get the Cinelog35. If you need to carry a GoPro for 8 to 10 minutes of smooth outdoor footage with wind resistance, the Cinebot35 is the better tool.
What You Need to Fly It
The Cinebot35 O4 Pro comes as BNF with an ELRS receiver, or PNP for your own. You will need DJI Goggles 3 or Goggles N3, a radio like the RadioMaster Pocket Crush, and a 6S 1100 to 1550mAh XT60 battery from our cinewhoop collection. At 583g all-up, this is well above the UK 250g threshold. You need an Operator ID from the CAA. See our UK drone laws guide for details.
Our Take
For outdoor cinematic FPV where you need ducted safety and GoPro payload capacity, the Cinebot35 O4 Pro is the most capable cinewhoop GEPRC has built. It is not subtle, it is not quiet, and it is not cheap. But the stock tune, the 60A AM32 power system, and the pre-configured GPS rescue make it the most complete BNF cinewhoop we have flown in this class.

FAQ
Q: Is the Cinebot35 suitable for indoor flying?
No. The ducted props generate significant thrust and noise. Oscar Liang rated it louder than his 5-inch freestyle quad. It is designed for outdoor cinematic work.
Q: What battery does the Cinebot35 O4 Pro use?
A 6S 1100 to 1550mAh LiPo with XT60 connector. A 1100mAh pack gives 5 to 6 minutes of mixed flying. Step up to 1550mAh for 8 to 10 minutes of gentle cruising, with the trade-off of roughly 76g extra weight.
Q: Does it come with GPS?
Yes. A GEP-M10Q GPS module is included with GPS Rescue mode pre-configured in Betaflight. Satellite lock takes about 80 seconds with roughly 25 satellites tracked.
Q: Can it carry a GoPro?
Yes. A GoPro mount is included. With a GoPro Hero 11 and 6S 1550mAh battery, all-up weight is 814g. Flight time drops to 4 to 5 minutes.
Q: What is the difference between the Cinebot35 and Cinelog35?
The Cinebot35 uses full prop ducts (more lift, more noise, better stability) and weighs 391g dry. The Cinelog35 uses prop guards (lighter at roughly 300g, quieter). The Cinebot35 is the outdoor payload hauler. The Cinelog35 is the close-quarters tool.
