DarwinFPV FoldApe4 is a small 4" drone suitable for a quiet cruise over the landscape. As the name implies, the FoldApe4 has folding arms and fits virtually in your pocket. The frame is designed to run on 3S batteries. Due to its light weight, the drone is quiet and has a long flight time (about 30min with Liion battery).
The drone uses 1504 size motors (similar to what you find on DJI drones). The drone also includes a GPS module, which allows you to see the distance and direction to the launch site as well as the speed in the OSD. It also supports automatic return. Flight control is handled by an AIO board with F411 processor and 15A BlHeli_S ESCs. The board also includes an integrated ELRS receiver.
Recommended batteries are 3S 1000-1300mAh Lipo or 3S 18650 Liion.
