If we are talking about flying time, then battery life is to be taken into account. And in that case, the DJI brand is the top name, with products having the flying time of 31minutes, 30minutes, and 27minutes. You can explore this brand on our shopping platform, Shops.ae. Another brand Yuneec has a product with 25minutes of flying time. Likewise, there are more technical features you need to dig into before purchasing, like an obstacle advanced system. All we want to say is do not get lured by just seeing the flying time but instead scrutinise the whole product before finalising.
