Just because the size is small does not mean that it is lacking power. This tiny beast is capable of running on 3s motors and most recently it was used in Shanghai to race against some of the top pilots in the world all while they were using 250mm sized quads. It also has been a proven winner of micro class at race track while our team pilot Kakei Leung got the 1st place at Hongkong Mini Class Drone Race.This frame is equipped with the very well accepted Gemfan BN2035 propellers and uses the flycolor S-Tower which incorporates betaflight OSD, F3 flight controller, and 4 in one ESCs. The Dragonfly MC1105 7500kv motors have been getting rave reviews and are also used on this frame. We dont stop there though, with this build you can say goodbye to those nasty little 2 dollar board cameras . Weve made this one standard to use the Run Cam micro swift which is much more expensive than the cheap cameras but the picture quality is well worth the extra details.
