hi, i have just received the APM 2.5 board and have been playing around with it, it looks like a very nice board.
I have one issue however that i am rather stuck on. The APM board will not arm with my ESCs plugged in. The ESCs are beeping rapidly. I have tried calibrating the ESCs manually using the receiver with no luck. I have also done multiple radio calibrations.
Any ideas on this is issue would be great, i found a few posts around but they didnt really solve the issue.
Also, another quick question, which telemetry received will work with my laptop so i can use the flight planner and be connected to the USB board while im flying
Thanks guys!

I have now managed to get the board to arm fine. However the best i can do is only get one motor working. And its extremely touchy on the throttle and laggy (maybe settings here not sure).
The other 3 ESCs just beep rapidly, i have had it so all 4 ESCs are giving me slow beeps, maybe like 1 a second. When arming the board, no motors will go.
Tried re flashing the f/w, re calibrating the radio and re calibrating the board itself, with no luck.
Any more ideas,
Thanks for the help!!
When you say the APM will not arm, do you mean that the board won't arm (fast blinking LEDs, then solid), or that APM does arm, but the armed board isn't driving the escs right?
