Overview
DarwinFPV BabyApe II FPV Drone RTF is a ready-to-fly analog FPV kit designed to help beginners get started without needing to match parts separately. The kit combines the BabyApe II 4S analog FPV drone, RadioMaster TX12 Mark II transmitter, VR009 5.8G 40CH 3-inch FPV goggles/monitor, 4S 850mAh batteries, and a balance charger.
Compared with the first-generation Baby Ape, BabyApe II uses a new power system and more reliable manufacturing technology. With a 4S 850mAh battery, hovering time is up to 13 minutes, furthest distance is 1.5 km, and top speed is 92 km/h.
