I'm quite happy with the phantom as a machine. Not had any dramas besides a bad battery. Obviously a stronger gimbal and camera. I'm sure others can think of improvements . I find the app the biggest let down. The forums here show I'm not alone complaining about signal loss or app freezing. A simple connection for goggles would be great. We all know what a pain sun glare can be. Smooth camera tilt from the app is a must as it is way to jerky. S1 and S2 switches display and notification would be nice. I wish when switching to fail safe the app didn't read 'signal lost' it should read 'fail safe engaged' or similar. I also think that a voice speaker wouldn't be a bad idea for beginners and the lights can be hard to see in bright sun. I'm sure it would cost less than $1. A simple "home lock set" voice would be nice. I'm thinking a friendly female voice. I would call her Aerial. Heck, even my robot vacuum cleaner talks and it can't fly away or chop peoples heads off. I can think of more but would like to hear from others.
