Apologize if this has been asked before but my top speed for my spark is 14 mph. Using the controller I have beginner mode and obstacle avoidance off. Also have sport mode on. The specs indicate that in a no wind situation it can reach 31 mph. I'm nowhere close. I have also recalibrated the stick controls.
According to my flight logs, I've had mine up to 23.8 mph at some point without actually trying to go fast. I've never tried to see how fast it could go.
