"Cycle does not have to do with the board's loop frequency. I believe it has to do with the chemical process in the battery. I think a few more examples will help you apply the calculation to your build. Turnigy 4000mAh 3S 30C = maximum…"

"C rating is the discharge rate. This is the number of time the batteries average that you can safely use in one 'cycle'. For example, if you have this battery: Turnigy 4000mAh 3S 30C Lipo Pack It can handle 4000mAh * 30C draw.…"

"Yes, downloading logs over telemetry using xbee/3dr radios has been stated as being too big to do. On this thread there was a conversation with Chris Anderson and a developer about this very topic. I don't know about the reset after using CLI.…"

Derek Ernewein replied to Randy's discussion ArduCopter 2.9 / 2.9.1 released
"CLI only works over Xbee/3rd radio if you connect to cli within 20-30 seconds of powering on the board. This is for safety so that you cannot connect to CLI over Xbee/3DR radio while in flight."

"I think that you would also benefit from posting on rccanada.ca for more general RC and multi rotor users. There are not that many drone/UAV users there, but lots of aerial photography and video people. They would likely have great stories about how…"

Derek Ernewein replied to Dave Whittington's discussion Test my APM 2.5 by riding along in a friend's aircraft
"With ArduCopter the APM only stored logs in the dataflash after it is armed. Is this incorrect or is arming only specific to ArduCopter? I have never used ArduPlane, but I have a need for logging much like Dave Whittington but…"

"It could also be good to add a "Test Failsafe" button in Mission Planner that watches for this, and tells you if you did did the failsafe. Clearly test with props off, but at lease if Mission Planner can simplify it to a button, then tell…"

Derek Ernewein replied to Marooned's discussion Working with logs.
"I agree that it is very confusing with the current interface. Even after I follow the right steps it still sometime doesn't work. It just prints unreadable characters forever and never does anything useful."

Derek Ernewein replied to theclam's discussion Wow - Thank you GPS/Telemetry!!!
"I love the way this was written. However, do you know why the geofence didn't work? Why the altitude showed as -41'? We should be able to use this to make sure that it never happens to anyone ever again. Thanks again for your story!"

"Is there some way to log the input signals from the Rx? That would help find issues like this, or at least point out user error."

"Perhaps if you enable all logging as attach logs someone will help. It would also be best to start a new Forum Thread of your own with all of your specs and settings."
