I suppose in the coming years most drones, smaller sizes included, will get sensors to prevent collisions, be waterproof (at list weather proofed), and other security features, maybe to retrieve them after a fly away. I'd take that.
Also think real time Youtube and Facebook upload, that could sell more than most technical improvements ? I don't need it.
To my taste, I'd like the same bird, with small improvements. Most point already figure in previous posts :
1. Camera is fine, but I'd appreciate a slightly better IQ, at least in the periphery of the image. Maybe a larger sensor (same resolution) and better optics. Optical zoom, only if the end result is less IQ loss and more power !
2. Drone :
a. hand landing is not always straightforward, and you need to force it to the side to stop it
b. stronger micro SD holder, or slot, even with the same concept there are stronger versions
c. (legs and their fixation,and gimbal, all look weak, but some flexibility doesn't mean they really are..)
3. More robust controller design :
a. USB plug is a joke, if you lay the controller on a flat surface with an average phone mounted, most weight is applying a force on the plug ! that would be easy to correct
b. many smartphones just won't fit, too thick or buttons on the side, and the phone holder could be more secure (I don't know exactly how, but I'd bet someone could)
c. on/off switch (more complex if you keep the open/closed switch) and removable joysticks would be nice
d. the command to rise/lower the camera should be proportional, now it's just up/down no matter how far you move it. Pushing it fully should lower the camera faster than just pushing it slightly
That said, most of todays options are fine, controller feels right in the hand, and the screen above hands position is more natural than the opposite !
4. Software :
a. selection of all the video and photos options in Flight Plan app, too
b. save a position/altitude in flight (when hovering) to use later in FP
c. PC software to run Flight Plan, grids would be top ! but then you need to handle all the photos, stitch them together, etc., make it more expensive than Android Flight Plan, if needed !
Bigger battery would most likely mean a whole new design, and accusync is useless in Europe for a small drone (you are not allowed to go further than visual, so...).
