JJRC X21 is added to the long list of DJI MINI 2 alternatives. It has a compact size with folding arms and a wheelbase of 200mm. Its 1503 type brushless motors are equipped with 5″ folding propellers that provide level 5 wind resistance.
The selling point of the JJRC X21 is the 360° Laser Obstacle Avoidance System. Thanks to the OAS module it can avoid collisions with buildings, trees, or other obstacles. Furthermore, it has GPS and Optical Flow positions that allow stable flight in both indoor and outdoor environments.
According to the advertised specs, the 2S/2800mAh battery allows about 20 minutes of flight time. By comparison, the DJI MINI 2 is powered by a 2s/2250mAh pack and has up to 31 minutes of battery life.
Its 4K main camera is installed on a 3-axis gimbal and features 5Ghz WIFI real-time image transmission. The angle of the camera can be remotely adjusted.
Thanks to the fail-safe return to home (RTH) function, in case of remote controller signal loss or low flight battery voltage, the drone will return autonomously to the take-off point.

The JJRC X21 DISCERN is offered with and without the Laser OAS module. While the JJRC X21 Pro with OAS is priced for $139.99 at Banggood, the basic edition without OAS is only $114.99. You can opt for one or two flight batteries.
