Sub250 OasisFly35 DC WTFPV GPS — 175mm Freestyle Quad (Bring Your Own O4 Pro)

WTFPV stands for "Where's The FPV camera?" — because there isn't one in the box, and that's entirely the point. The Sub250 OasisFly35 DC WTFPV is the same 175mm, sub-250g freestyle weapon as its O4 Pro sibling, minus the air unit you were going to buy separately anyway. Bolt in your own DJI O4 Pro, O3 or analog setup — Sub250's frame takes all three — and you've got a RedFox A3 45A AIO (F7) flight controller, 1804 3450KV motors and SUB-M10 GPS ready to go. Available in PNP or ELRS, for whichever radio religion you subscribe to.

Why You Want It

Because your cinewhoop is "plenty fast" in the same way your diet starts Monday. The OasisFly35 DC gives you proper 3.5-inch snap, a dead-cat frame that keeps props out of your footage, and GPS rescue for the moments your ambition outlives your orientation. At 162g bare (around 213g with a 4S 530mAh), the CAA paperwork stays in the drawer where it belongs. And since you're supplying the air unit, you're not paying twice for one you already own — see, we're practically saving you money. (We still profit when you buy it. Crazy, right?)

Specifications

• Wheelbase: 175mm (3.5-inch props, zero cinewhoop energy)
• Frame Plates: 3.5mm arms / 1.5mm bottom / 2.5mm mid / 2.0mm top (carbon, obviously)
• Motor Mounting: 9×9mm / 12×12mm patterns
• Motors: 1804 3450KV (the fun kind of overkill)
• Flight Controller: RedFox A3 45A AIO — STM32F722, ICM42688-P IMU, BLHeli_32 ESCs
• VTX: None — that's the "WTF" part. Fits DJI O4 Pro, O3 or analog
• Receiver: ELRS 2.4GHz or PNP (your receiver, your problem)
• GPS: SUB-M10 (rescue mode that actually rescues)
• Propellers: HQ 3.5×3.5×3
• Recommended Battery: 4S 530mAh (not included — batteries don't grow on quads)
• Power Connector: XT30
• Weight: 162g bare / ~213g takeoff with 4S 530mAh (sub-250g, sub-drama)
• FC Firmware: Betaflight 4.5.2 (SUB250REDFOXF722AIO target)

Compatibility

The DC frame is officially compatible with DJI O4 Pro, DJI O3 and analog VTX setups — switch freely as your goggles collection dictates. This WTFPV version ships without an air unit, so you'll fit your own and then do the usual Betaflight dance (VTX table, ports, the sacred CLI ritual). Ships with Betaflight 4.5.2 on the Sub250 RedFox F722 AIO target, plays nicely with ExpressLRS v3+.

What's in the Box*

• 1× OasisFly35 DC WTFPV frame with electronics installed
• 1× set HQ 3.5×3.5×3 props (ready to slice air and ego)
• 1× GPS module pre-mounted
• 1× XT30 pigtail (pre-tinned because we care)
• Sticker pack (brand loyalty is half the fun)

Disclaimer

*Accessory contents may vary depending on our supply chain's mood swings, but your OasisFly35 will always ship fully functional. One thing it will never ship with: a camera or air unit. That's the whole WTFPV deal — bring your own O4 Pro, O3 or analog gear, plus a 4S battery, or enjoy the world's most expensive paperweight.

Still Here?

Either you're cross-checking wheelbases against your spare O4 Pro (respect) or procrastinating on soldering. Either way, that air unit on your shelf deserves better than a drawer. Add to cart — your future self will call it a "sensible investment."
