GEPRC Vapor-D5 Guide: WTFPV vs Analog vs O3 vs O4 Pro
The GEPRC Vapor-D5 is one 5-inch freestyle platform sold in four video versions — WTFPV (no video system, bring your own), Analog (MATEN 5.8G 1.6W VTX + Caddx H1 camera), DJI O3 and DJI O4 Pro — and the shortest answer is: pick WTFPV if you already own a video stack, Analog for classic 5.8G reliability, O3 for proven digital HD on a budget, and O4 Pro for the newest sensor and the longest rated flight time (14–19 min vs 13–17 min on the others). All four share the same core: GEP-F722-HD V2 flight controller (STM32F722, ICM42688-P gyro), TAKER H60_BLS 60A 4-in-1 ESC, SPEEDX2 2207E 1960KV motors, GEMFAN 5136 props and a DC frame that keeps propellers out of the camera view. This guide compares the four versions line by line so you can match one to your goggles and budget.
What exactly changes between the four Vapor-D5 versions?
GEPRC kept the drivetrain identical across the family and changed only what carries video — plus the small weight and battery consequences that follow. Here is the full picture from the product pages.
| Spec | WTFPV | Analog | DJI O3 | DJI O4 Pro |
|---|---|---|---|---|
| VTX | — | MATEN 5.8G 1.6W | O3 Air Unit | O4 Air Unit Pro |
| Camera | — | Caddx H1 | O3 Camera | O4 Pro Camera |
| Antenna | — | Momoda2 5.8G RHCP | O3 original | O4 Pro original |
| Weight (PNP) | 397g±5g | 428g±5g | 435g±5g | 428g±5g |
| Battery (rec.) | 6S 1550–2200mAh | 6S 1550–2200mAh | 6S 1550–2200mAh | 6S 1300–1800mAh |
| Flight time | 13–17 min | 13–17 min | 13–17 min | 14–19 min |
| Wheelbase | 238.43mm | 238.43mm | 238.43mm | 230mm |
Four rows tell the story: the Analog version adds just 31g over the bare WTFPV build (428g vs 397g), the O3 is the heaviest at 435g, and the O4 Pro swaps to a slightly shorter 230mm O4-specific frame while recommending smaller batteries — its 14–19 minute rating beats every other version despite the added HD gear.
Which version fits which pilot?
WTFPV: you already own a video system
The WTFPV ships with VTX, camera and antenna listed as “/” — deliberately empty, because this version targets pilots moving an existing HD or analog stack between builds. At 397g±5g it is the lightest, and it accepts any system that fits a 5-inch DC frame. If your goggles and air unit are already sorted, this is the cleanest entry.
Analog: the 1.6W long-range-minded choice
The Analog version pairs the MATEN 5.8G 1.6W VTX with a Caddx H1 camera and a Momoda2 RHCP antenna — a complete 5.8G chain at only 31g over the bare frame. Our MATEN VTX guide covers what 1.6W of output means for range and penetration in practice. For pilots who fly in groups on 5.8G or want the cheapest goggles entry, this remains the most cost-efficient version.
DJI O3 and O4 Pro: the digital path
The O3 version carries the proven O3 Air Unit; the O4 Pro version steps up to the O4 Air Unit Pro with its larger CMOS sensor — the product page highlights improved image detail and light sensitivity, plus new aluminum lens components and shock-absorbing silicone to cut vibrations. That sensor upgrade is also why GEPRC tuned the O4 Pro around a dedicated 230mm frame and narrower 1300–1800mAh battery window: less pack weight balances the heavier video payload, and the rated 14–19 minutes makes it the endurance pick. For another O4 Pro 5-inch with a Wide-X/DC choice, see our MARK5 O4 Pro guide.
What stays identical across all four?
The flight electronics are the same everywhere: GEP-F722-HD V2 FC (STM32F722 MCU, ICM42688-P gyro on SPI, barometer), Betaflight OSD via AT7456E, and the TAKER H60_BLS 60A 4-in-1 ESC on 6S. Motors are SPEEDX2 2207E 1960KV spinning GEMFAN 5136 props, power arrives over XT60, and every version accepts PNP, GEPRC ELRS24 or TBS Nano RX receivers plus an optional GEP-M10 GPS. The DC structure keeps propellers out of the camera frame, CNC aluminum side panels and a front lens guard protect the camera, arms are 5.0mm carbon, and every kit includes a GoPro mount, two spare 5136 props, two M20×250mm battery straps and both 1.5mm/2.0mm screwdrivers.
How does it fly and for how long?
The product pages rate flight time at 13–17 minutes (14–19 on O4 Pro) on recommended 6S packs — freestyle-session territory, not long-range. If range is your actual goal, the same 5mm-arm durability philosophy scales up in the MOZ7 V2 long-range guide; and if you want a compact cinewhoop instead of a 5-inch freestyle rig, our Cinelog30 V3 O4 Pro guide covers that class. For the D5 itself, the 1960KV motor spec and 5136 props are tuned for controlled, camera-friendly power rather than outright speed.
Frequently Asked Questions
Which Vapor-D5 version is lightest?
The WTFPV at 397g±5g — it carries no video system. The Analog and O4 Pro weigh 428g±5g each, and the O3 is heaviest at 435g±5g.
Do all four versions use the same flight controller?
Yes — the GEP-F722-HD V2 (STM32F722, ICM42688-P gyro, Betaflight OSD with AT7456E) and the TAKER H60_BLS 60A 4-in-1 ESC are shared across the family, along with SPEEDX2 2207E 1960KV motors and GEMFAN 5136 props.
What battery should I use with the O4 Pro version?
GEPRC recommends 6S 1300–1800mAh for the O4 Pro — a narrower window than the 1550–2200mAh used by the other three versions, balancing the heavier video payload while still delivering the longest rated flight time (14–19 min).
Can I add my own GPS to the Vapor-D5?
Yes — every version lists the GEP-M10 GPS as an optional accessory; it is not included by default.
Does the DC structure really hide the propellers?
That is its purpose — the DC design evolved from the Wide X layout specifically so the camera does not capture propellers in view, improving video quality; CNC side panels and the front lip add camera protection.
Which Vapor-D5 should you buy?
Match the version to the video system you want to live with: WTFPV if your stack is already chosen, Analog for the complete 1.6W 5.8G chain at 428g, DJI O3 for proven digital HD, and DJI O4 Pro if the newest sensor and 14–19 minute flight times justify the narrower battery window. The platform underneath — F722-HD V2, 60A ESC, 2207E 1960KV — is identical, so no version is a compromise on flight hardware. Unsure which matches your goggles?
