Whirlwind Quadcopter will not bind.
I just purchased this new in a sealed box. I installed new batteries in the transmitter. The display shows a full battery on it. I charged and tried both batteries for the quadcopter. No matter how or in what sequence I turn on the transmitter and attach the battery, the quadcopter will not bind to the radio. I followed the instructions exactly and also varied the procedures used on my other quadcopters, (I own around 35 quadcopters), I can not get it to bind. The LED on the board repeats the same sequence of blinking twice then off then blinks twice again. I'm open to suggestions before I request an exchange or refund. Thanks.
