"Hi Martin. I'm guessing you're running the two packs in parallel? If so why dont you just wait for the gyros to calibrate before you plug the 2nd battery in...?"
"Randy,
I loaded 3.1.5 on my APM1 quad and noticed that there are no sonar readings in the MP. I checked it in CLI and I do get a reading there. I have enabled the sonar and I've selected XL-EZ0 in the MP. Any ideas perhaps? Thanks,"
"Disabling the sonar only dropped it by 4kb - I need another 16kb to get it under 258kb. Someone else mentioned something about disabling unused flight modes perhaps; is that possible? PS: Can you point me towards the mailing list perhaps? Thanks"
"Randy,
Ok I've changed all instances of "relay.on()" and "relay.off()" to "relay.on(0)" and "relay.off(0)" in my UserCode file and it's compiling, but sadly it's coming in too big now at 278kb. Are there any other features I can choose to disable…"
"I add some custom code in order to use the relay to control my LEDs as a voltage indicator - hence I need to manually compile through Arduino each time..."
"Hi Randy,
Is the relay still supported on the APM1 boards? I've been following the developments but I haven't actively tried anything since 3.1-rc5 and now when I try to compile I get the attached errors. I've also attached my own little HOW TO…"
"Well another year has almost gone past and because I haven't worked on my ArduCopter quad for some time I thought I'd try the latest RC firmware but once again I'm getting various errors when trying to compile. Kevin do you perhaps know of any…"
"I have a sonar on my APM1 quad. I haven't flown it for a long while but I found that a sonar_gain of 0.6 works the best for me, however it's nowhere as good as in the previous versions. Have a look here - https://vimeo.com/81257936"
"Do you always do your test flying in the same spot as in the video? Have you ever tried it in a open field perhaps? GPS signals will bounce off buildings giving you a less accurate lock..."
