hi,Is it possible to connect my ezuhf diversity receiver to the apm 2.6 using only one servo cable(ppm i believe it is called). This will be great if it is do-able.Continue

@Marooned

Hmm. Do you mean using Mission Planner to upload the 2.7.3 firmware erases the existing radio calibration?

If that's the case, we should not have to redo the radio calibration since we uploaded both 2.7.3 and our custom program through the Arduino compiler and not Mission Planner.

Updating to 2.7.3 erased eeprom hence this radio calibration. Updating to earlier firmwares left eeprom so no calibration was needed. Anyway, I just wrote what helped me in similar situation. You can try (it takes no more than a minute) or wait for other hints.

@Marooned
The team moved from the 2.7.3 to our custom program without performing radio calibration and did not have any problems. But moving back, the 2.7.3 produced no response.
If shifting from one firmware to the next did not give any problem, shifting back to the first should not either.. Right? Pretty perplexed here.

Zachary: did you do radio calibration after uploading new firmware? I forgot about it and had the same effect as you described.

@Randy
THANKS. I was extremely worried that my programming could have created some problem with the power distribution and inadvertently fried the apm.

But now, we realized that our NEW program allows the apm to function properly (i.e. board powers up, ESCs arm, motors respond to throttle input). However, uploading the regular ArduCopter 2.7.3, the motors stay in calibration mode (consistent beeping), regardless of what we do. Do you know why?

As for ESC overheating, is it caused by malfunctioning power distribution?

Thanks.

@Zachary re frying board through errors in the arducopter program,

    I don't think that's possible.  For things like an ESC where you've got large voltages that are being controlled by the firmware it's possible but as for the arducopter software, it's just running a program that changes signal out to ESCs, xbees, etc so I can't imagine how that could happen.

Is it possible to fry your apm board through errors in the arducopter program?

How to add a flight mode of my own. .. ??

@Lucas re obstacle avoidance,

    Somebody asked that same question on the sonar wiki earlier today, i guess it's a popular thing that people want.  We don't support that at the moment and no specific plans to add it although it wouldn't be too difficult.  People would have to buy at least 4 more sonars though..$120-ish..not terrible i guess.

What are the features that can be realised for an Arducopter? 
Are there something like obstacles avoidance?
