Hello,
just received my first APM 2.5 today, i am having trouble getting the turnigy plush 30 amp speed controls to arm. I have gone through the manual esc calibration and tried to do the auto as well. Manual works but when i plug them back in to the amp2 they will not arm, just a steady beep every second. I have ready alot of other threads with this same problem and i have tried to power the board first and then plug in the battery and that did not work. I have tried moving my throttle endpoints and recalibrating the radio and nothing has helped, is there a solution for this or do i have to buy some new speed controls?

i probably tried it about 50 times and it never armed one of them. hopefully i will get my new dji opto esc's and dont have any problems.
ok i just plugged the apm2 into my dji 30amp opto speed controls and they arm just fine.
Thanks for the reply eddie, i plugged a servo into output 5 and it moves along with my throttle stick ( it is kind of notchy, and jumps to zero around 15% throttle ). I tried to do the auto calibration and the apm2 is outputting the signal correctly according to the servo but the speed controllers will not arm. I even tried powering the apm separately and arming the apm2 with the throttle stick before i plug in the battery and they still will not arm, but the servo shows the apm outputting signal. any ideas? thanks again fro the reply.
I'm using the Turnigy Plush 40A ESC and it worked fine. I had already calibrated it with my radio before I bought the APM2.0. I just plugged it all in calibrated my radio in the Mission Planner and never gave it a second thought. In case it matters, I removed JP1 and powered both input and output rails with two separate 5A BECs. Only the signal wire from the ESC is connected to the output rail.
A steady beep every second is what the ESC does when it's not receiving a signal from the receiver. Have you confirmed that a servo works correctly when plugged in along side the ESC?
