RE: Dynam E-Razor 450
before you fly this heli it's very important that you fully understand what this flying machine can do. Do not flip the 3d switch unless you know how to fly 3d, which should be 2 to 3 years down the road for you.
If your ESC continued to beep non stop in a sequence, that means it entered programming mode. You must start the heli normally, left joystick down, speed trim down, turn on the radio, connect the battery to the ESC and wait 10 second with the heli sitting on a flat surface.
