After switching the SpeedyBee 2.5 over from 3S to 4S packs, the drone came alive with a whole new level of responsiveness. The extra voltage instantly sharpened throttle authority, giving snappier punch-outs and much more confident recovery from dives. During freestyle moves, the quad felt tighter and more locked-in, with quicker transitions, smoother power delivery, and enough overhead to pull out of aggressive maneuvers without bogging. Even with the added speed, the frame and tune handled the power well, making the whole flight feel more energetic, controlled, and fun.
