Both machines performed beautifully and I was impressed by the workmanship . . as well as a ton of subtle new features . . like single gimbal stabilizer. . . or joysticks that stow away for packing in small spaces. They are both VERY well engineered in "form and fit" everything tight and smooth. . .even better than the original Mav and that was definitely a step above the competition already. They have a very solid FEEL. I was surprised at the extra "air Time" . . kept waiting for the battery low warning even though I'd been flying more than 20min already still have 10 min left. Great for getting home. I may not understand tripod mode switch on the side but it seemed to do nothing. I expected it to fly very slow and smooth but seemed to have no effect. SPORT mode is quite a racer.
I tested the Collision Avoidance (front back and side) very accurate . . if it is going to miss you it will not stop and you need to be aware of that so as not to scare yourself or others. Made a couple of direct passes it myself and it stopped when low enough to hit my head but just 6inches above and it kept on coming . . whizzed by happily . . . I ducked!
I did not mess with the aperature yet . . need to learn more about that still. . . but The Optical Zoom and "one finger gimbal pan" was really nice and smooth too.
All in all a very successful and impressive first flight.
