Simply put.....amazing! My Yuneec Q500 4K performed as advertised. I followed the pre-flight inspection and compass calibration procedures and some additional experienced user YouTube video session advice. Flawless. I did have to purchase another battery before my flight because the one supplied in my kit did not charge (red steady error light on charger). Discovered how to inspect the battery and found mine exhibits the symptoms of a defective battery. I have written for a replacement since its still under warranty. I am very pleased by the performance and ease of use. This drone rocks!!!
