I about to make the servo cables between my RX & APM 2.5. The wiki 'Connecting your RC motors' shows that I must connect the cable's negative pin to the out side of the APM board.
The JR manual doesn't have a RX pin-out diagram.
My question is.... wha

If anyone could help me with:

I have been setting up my configuration of my APM2.5 with 3DR Radio Telemetry link.
I've noticed what seems to be quite a serious problem. I am powering my plane using my Lab PSU which limits current. If the motor kicks in and triggers a current li

I´m with the new APM2.5, firmware V-2.7.3. When I open CLI, it displays what appears on the attached image (CLI). The "hieroglyph" appears endless until I hit enter 3 times. Also says, "No dataflash inserted".
In addition, when I try to ch

My question is (for anyone more familiar with optical flow technology than I am), can I expect this sensor to be significantly better than the current Arducopter optical flow? And can I expe

Not sure if this is an AR8000 receiver issue or a Skektrum DX8 issue or just me messing up on the wiring from my APM 2.5.
I've had this same issue with my quad and now I see it on my hex.
I followed Mr. Hansen's post on setting up a Spektrum DX8

I like to keep my tlog files short while I am doing multiple tests with APM 2.5 on the ground hooked to my laptop - therefore, I "Disconnect" (hit the far right button on MP - the APM is still powered by the USB cable) to end that tlog file. Then whe
