Flight Performance & Flight Time
Like any other DJI drone, the Spark's flight performance is one of the best in its class. Its 120mm 2-blade foldable propellers and brushless motors provide excellent propulsion for its 300g weight (without prop guards). With the Spark, DJI has aimed to get the best propulsion-to-weight ratio possible and its propellers, when aligned parallel to the fuselage are just 2mm from touching each other. In other words, DJI has put the largest possible motor and propeller combination on the Spark and the biggest possible battery it can.
The result is a drone that flies very well even in windy conditions. And when assisted by GPS and its Vision Positioning System (VPS), the Spark is very easy to fly and stable. The Spark's forward-facing sensors allow it to avoid flying into obstacles (when not flown too fast). Although the feature works fine most of the time, it does struggle in detecting fine obstacles such as power lines and thin tree branches.
