Sub250 DollyFly25 V2 HD 2.5" FPV Drone

You’re here to buy the Sub250 DollyFly25 V2 HD, and yes—we’re here to sell it, because sub-250g rigs with grown-up specs are catnip. This 2.5" ripper from pairs a stiff 2mm carbon frame with a Redfox F722 AIO and punchy 1404 motors. No VTX or camera included—by design—so you can run HD how you like and keep the build clean.

Please note this version does not inlcude any DJI O4 FPV system, so you will need to add your own

Why You Want It

This is a purpose-built platform for pilots who want agility without the fragility tax. The STM32F722 brain and ICM42688-P gyro deliver tight control, while 45A AIO headroom laughs at current spikes. At 148g (PNP), it’s light, fast, and honest—no marketing magic smoke, just solid engineering. Will it fly itself? No. Will it reward good thumbs? Very yes.
