Very excited to inform you that after Drone ELF successful take-off last week, we got the project a step further: now the flight height is 4m. 

We have now completed the mechanical design, ensuring the normal flight of Drone ELF.

But there’re still obstacles lying ahead like flexible operation, drift-off problem, ultrasonic height position function(one key departure, one key hover), BLE wireless burning, etc. 

But as ElecFreaks making great efforts on it, we have full confidence to give birth to an amazing helicopter. Stay focused~
