Hello. I am new to this forum but i have found a lot of great information so far. I have installed Open Solo 4 but the Solo has 2 blue lights on one side and a red and green on the other. Everything on the controller is good to go and when I hold fly all i get is 2 beeps from the Solo. I have tried multiple times and still the same thing. I am installing thru Solex. Can anyone help with this.
