Ok so I just did my first build but I can't get nano rx and micro tx to bind when I power up the Rx blinks slow green like it should then I press the yellow flashing light on the tx they both blink green and then the tx goes blue when I press the blue button to update the Rx starts blinking red... Any ever had this issue before I'm wandering if I need to flash both with the latest firmware(I have not) any help would be great you guys always have something helpful to say
