“I've owned every generation of the Fly6. This is by far the best. It has the two features I needed the most: long battery life (7hrs) and most importantly, video review. I once had to call law enforcement but was frustrated that I couldn't share the video when they arrived. The new app solves that problem. Other great features include the high res screen showing status, including batter level - very nice; and a solid hinged door instead of the rubber cover, to protect the memory card and charging port. It's a little heavier than the Gen 3, by approx 2.6oz or 76grams, and a little bulkier. But I prefer the sculptured shape of the Pro. The extra weight doesn't bother me. When weight counts in a race, I don't carry it. All other times, I do. A few extra grams don't matter. A little pricey but worth it for a little piece of mind.”
