I just bought a P2 controller from JIYI and have installed it. Everything working but it will not arm. I am using a 9x trunigy with a 9x receiver. Any suggestions on how to troubleshoot or how to get it to arm.
Never used the P2, but go to your receiver test and check that you are bound, no channels need to be reversed, and make sure you turn the radio BEFORE the transmitter. If this does not fix it I'll help you look into it a little deeper.
You will have to let us know how well that one performs. I have had my eye on it, but have not made the jump just yet. I bet its either something is reversed, or the sticks need to be calibrated like George stated.
