Sub250 released the latest Nanofly20. We created a 2-inch drone with a wheelbase of 88 mm and named it Nanofly20. you can experience the fun of it at home. Nanofly20 is equipped with the latest 1002 21000kv motor, which feels light and moves with your heart. Highly integrated FC, we have integrated all electronic products except the camera on one FC.

We will launch three versions of the Analog, HDZero, and Avatar. And we firmly believe that the small wheelbase FPV drone not only brings the characteristics of indoor flight but also a new kind of fun to freestyle in the courtyard. Nanofly20 will replace the 5-inch FPV drone in your hand and become your new choice for freestyle.
