Welcome to WattFlyer
Do you get response from any of the flight control inputs or is only the motors?
If you are getting nothing, take a look through the canopy front right side ( as you are looking from the tail) and see if you see a light flashing. If it is flashing, the receiver has not bound to your transmitter and you need to repeat the bind process.
Is your throttle stick set to zero when you put the battery in the heli? The speed control will not initialize unless the throttle is set to zero
