A:Answer The Spark shoots in a maximum of 1080p, along with a 2-axis gimbal. It has obstacle avoidance in the front, and the Mavic Mini is a replacement. The Mavic Mini has enhanced wifi, like the spark. However, it is better, and has evolved to fix problems that happened with the spark. The Mavic Mini has a 3-axis gimbal, can shoot videos in 2.7k, and shoot photos in 12MP. The only downside to the Mavic Mini is that it has no obstacle avoidance in the front. I recommend getting the fly more package, with a roll cage, if it is your first time with a drone, or if you want to protect/get maximum protection out of your investment.
