"You need to do one or the other but not both.  Strange that you get different results with each approach.. but try calibrating individually to see what happens. Good Luck."

"So when you calibrate the ESCs directly from the receiver they work fine? If so just plug them into the APM and dont try and calibrate any more  (assuming you have not tried that already)"

"Here is the config file it uses the following switches on the left side of the TX.  Please check the Mission Planner config and configure the flight modes to your liking.  You will then need to edit the flight conditions in the TX if you…"

"I will download my A9 configuration and send it to you later.  It has flight conditions built in so you can see the flight mode you are in on the transmitter.  I use 4 switches to get 6 modes.. 1 is setup to start a mission, 1 is RTL, the…"

"Impressive.  Big improvements for many of the areas I was interested in.  Looking forward to seeing this in MP in the near term."

"Thanks for the info. I am in fact hooked up to Channel 7 and 8, however I do not know how to be certain whether there is a performance benefit other than to eyeball it against the standard gimbal channels. I've started to take a look at the…"

"KevinB,     The best place to follow the progress of the next release is on the previous release's discussion thread.  So in this case, the discussion on the 2.9 release is going on on the 2.8.1 release thread which is…"

"I gave myself a crash course in Arduino this evening, and compiled an AC2.9rc1 hex file (605kB). I uncommented the APM2 hardware line in APM_Config.h, and left the source otherwise untouched. Can I simply flash the file to my APM2.5 with the latest…"

"Walther: once it's thoroughly tested by the dev team, it will be released to the public via the Mission Planner, as usual. Probably in the next couple weeks. "

"You can't. If you are a developer and would like to TEST, get it from http://code.google.com/p/arducopter/downloads/list and upload via Arduino, etc."

"New version ArduCopter-2.9-rc1. Where can i get this files compiled ready for upload to my APM 2.5 board? "

"Randy, what is INS? Also does Alt Hold also use the GPS for maintaining position/altitude if the GPS is blue when start?"

"i think there are too many released for apm 2.5....the team should wait before to release a new version and try to fix all bugs  it s the reason why arducopter is not very famous like multiwii..in the begining of the project lots of people had…"

"Here is a video that shows where the Naza baro is located (not my video): http://www.youtube.com/watch?feature=player_embedded&v=02i78oxL_EE#!"

"The chip on the bottom left of the upper image looks very much like a 3-axis compass.  Could be the same one we use on the APM2.. Looks like they've got an ARM processor on the top right, right near the white blob...so a separate processor…"

" Here's some photos from inside the NAZA GPS unit - it's interesting that the tops of the ICs (chips) have been "etched" to hide any markings... "
