Hi,
From watching your introduction I noticed Blynk has drone(quadcopter) control feature. I would like use that feature. Any suggestion? Where should I start?
Is any technical specifications or details available yet? 
@DBear
Joystick widget is in progress currently. So I believe you’ll be able to do that soon. We are currently providing internet communication only, which I think might limit drone’s capabilities. But you can still build an architecture like:
Smartphone - internet - arduino - radio - drone

Yes, it does. Just install local server, and you are good to go.
@DBear
You also asked me about an interface via email. Could you tell us what would you like to see?
@Pavel,
UI design, its’ look of joysticks and buttons, their positions whether more button could be added etc. From sending button/joystick data, how does it send? What will be format?
Currently our quadcopter receives joystick inputs via UDP, left and right joystick positions will be send in sequencial 4 packets. In simple char figure:
| Smartphone | --> (WiFI AP) <–> (Our drone)
You can add widgets in the app and arrange them in any way. This is one of the Blynk powers 
We use TCP/IP for connection. The average size of 1 packet is ~14bytes.
You can take a look on our libraries and server code here: https://github.com/blynkkk

Indeed, we could do UDP, when finish other high priority tasks like all widgets =). And anyway it will still require server.
Regarding message size it is indeed ~10 bytes + TCP/IP header itself 40 bytes, so ~50 bytes in total for average hardware command.

Hey guys, did you manage to pull this off?
Im trying to find a way to connect smartphone to AP(esp8266) to control GPIO without using internet/router… I guess you guys are trying the same thing?

Hey guys, Anybody here was able to fly his quadcopter through Blynk. I am working on it and would like to know how that works.
