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.

3S Power / 2.5″ Props

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

4S Power / 2″ Props

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.

While the Firefly 25MINI excels in long-range efficiency (up to 12 minutes flight time), the Firefly 20PRO is a bando-basher capable of speeds exceeding 120km/h. Equipped with a custom anti-vibration gimbal adjustable from 0° to 25°, it ensures jello-free, high-speed footage that was previously impossible for micro-class drones.
