I have here a working long range multorotor (a Hoverthings Flip FPV), with an ImmersionRC EzUHF receiver and EzUHF transmitter module for my Graupner MX12. The multirotor is using like the P2V a NAZA V2. For fun I replaced the receiver from the P2V with the EzUHF receiver. I also connected all the needed connections. A > CH2 E > CH3 T > CH1 R > CH4 U > CH5 X2 > CH6 X3 > Power from the main board. After powering up the transmitter and the P2V, the transmitter and receiver connected okay (bind) , but the P2V jumped into failsave mode with blinking constant flashing yellow. The startup CSC did also not work I've had a look with the DJI Phantom 2 Assistant, and it showed failsave mode (none of the sliders moved) Looking (with Naza-M v2 Assistant Software) at the working setup on the Flip FPV the "receiver type" is set to Traditional. With a working P2V it's set to D-Bus. Unfortunately I can not get a working USB connection with the Naza-M v2 Assistant Software v2.20 and the P2V NAZA V2 Anyone here who might know how to set the P2V's NAZA V2 receiver type into "Traditional" mode?
