How can i control quadcopter with blynk and nodemcu esp8266?

“blynk-cloud.com” is the old blynk server. The new blynk server is"blynk.cloud". Also, there’s no need to specify a server, just add the #define BLYNK_TEMPLATE_ID "TMPLxxxxxx" #define BLYNK_DEVICE_NAME "Device" #define BLYNK_AUTH_TOKEN "YourAuthToken" At the top of your sketch and use Blynk.begin(auth, ssid, pass); Instead.
