Sub250 OasisFly35 - 4S ELRS with GPS

Sub250 OasisFly35 is a 3.5″ freestyle drone with analog video transmission. The drone is configured as Deadcat, where the front arms are moved further back, and the edges of the props are not visible in the FPV image. The drone is equipped with a GPS module, which supports automatic return to the takeoff point. The image also displays the distance and direction to the takeoff point. The electronics are protected by plastic side plates from grass and other debris. The FPV camera is mounted in aluminum side plates via rubber grommets that reduce vibration transmission to the image. The arms are cut from 3.5mm thick carbon for greater durability.

The propulsion is provided by 1804 3450KV motors combined with HQProp 3.5x3.5x3 props and a 4S battery. Flight control is managed by the AIO board Redfox A3 with a F722 processor, ICM42688P gyro, barometer for height measurement, and 16MB memory for blackbox. Integrated ESCs with BLHeli_32 firmware can handle up to 45A. Video transmission is provided by an analog camera Caddx H1 and a video transmitter Sub250 Send T1600 with a power of up to 1600mW. The drone is equipped with an external ELRS receiver operating at 2.4GHz.

The recommended battery is a 4S 500–650mAh with an XT30 connector.
