Breaking the Mold
Swap Your VTX in Seconds
Just 4 screws.
Why build twice? We engineered the top plate to house the entire digital VTX and antenna system, keeping the powertrain bolted to the bottom. No re-soldering.
In under 3 minutes, transplant your Digital VTX to the other frame. Go from a 3S cinematic cruiser to a 4S bando basher effortlessly.
Distinct Power. Infinite Ways to Rip.
Factory pre-tuned PIDs. Locked-in feel right out of the box. Zero prop wash.
Firefly 25MINI
The ultimate cinematic cruiser. The wider wheelbase and efficient 3S powertrain shatter the micro drone flight time barrier. Enjoy buttery smooth lines and rock-solid wind resistance.
Built For:
- Long-range freestyle (Up to 12 mins)
- Cinematic FPV & scenic dives
- Smooth indoor/outdoor cruising
Firefly 20PRO
Pure adrenaline. A tight, aggressive frame packing a brutal 4S punch. Hovers at just 22% throttle and screams up to 120km/h. Instant punch-outs for tight gaps and violent acrobatics.
Built For:
- Bando bashing & high-burst racing
- High-speed tracking & chasing
- Aggressive freestyle maneuvers
Purpose-Built Details. Pure FPV.
Crash-Resistant Frame
To fly hard, you need to crash hard. Both models feature a rigid 2.5mm high-strength carbon bottom plate. We’ve implemented a unibody front-arm structure to dramatically increase bend resistance. Stop worrying about snapped arms and focus on hitting those gaps.
High Speed. Jello-Free.
Our custom anti-vibration gimbal mount features a high-precision dampening structure that effectively filters out high-frequency frame vibrations. The lens is adjustable from 0° to 25°, perfectly accommodating flat cinematic cruising or pitched-forward racing. Perfectly paired with O4 PRO/O4 for buttery smooth HD footage.
