Does anyone know where I can buy a version 1.1.1 receiver? It's the one with to antennas and I can't seem to find one any where online for sale! My transmitter won't work 2 to 3 feet away from Phantom and I used a new transmitter from another Phantom I bought so I ruled the transmitter out now I want to see and hope its just the receiver and not within the Naza! Also can I buy a different receiver like another Futaba receiver for it with out having to change out the transmitter and what modal or type would work??
