From Firefly18 to Firefly30 — 18650 Li-ion FPV Experiment

Firefly18 on steroids — or maybe Firefly30? In this video, I move the Firefly18 electronics stack and camera onto a Crux3 frame and test how well a single 18650 Li-ion battery works on a micro FPV drone. This build focuses on efficiency and endurance, not raw power. Build components: Crux3 frame Happymodel EX1202.5 11500KV motors 3018 propellers 18650 Li-ion batteries (LiitoKala & Molicel P30B) What’s tested in this video: Indoor and outdoor FPV flights Flight time testing with 18650 Li-ion Low-voltage performance PID & Rates tuning for Li-ion efficiency Jello effect and how PID tuning eliminates it Results: ✔️ Firefly18 can fly with a 18650 Li-ion battery ✔️ Over 18.5 minutes of flight time ✔️ Molicel P30B delivers better current at low voltage than LiitoKala HG2 ✔️ PID & Rates tuning removes jello ⚠️ Frame, motors, and propellers must be upgraded for this setup link to Firefly18 O4 Drone - https://flywoo.net/products/firefly18... 📦 Links to all parts used in this build: GOKU 1s 12A AIO Plug&Play - https://flywoo.net/products/goku-f405...
