Hi All,
I have several multicopters with Wookong and Nazam which have been great but am now looking for more flexibility with AC.
I have built a new frame, installed an APM2 with Digi XTend modems and have established communications and followed the guide closely. I have calibrated escapes and IMU. Failsafe is set. Checked the throttle drops below 975 on radio loss and checked and re-checked motor directions. I have strapped the quad down and taken it up to full power with no problems.
Question 1;
The guide says;
In this tab, you can tell APM what optional sensors you have connected. (Remember that if you're flying with a GPS, you MUST use a magnetometer, too). Just click the check box for any sensor you're using.
I only have the APM2 with the gps daughter board. Does this mean that I need an aditional magnetometer? or do I use the one on the board? Do I click that I have a compass?
Question 2.
I have researched the forums extensively and tried to pick up all the bugs that have caused crashes (there appear to be a lot of them) and have made any recommended changes (including soldering the gps board pins). Is there a "Crash List" somewhere of all the bugs that have caused crashes and the appropriate remedies?
Any help would be appreciated. Really looking forward to my first flight.
Thanks.

For Q1.
Yes, use the on board mag. You will need to click that check box saying that you have one. Also, you will need to calibrate it for you location. Use this site http://www.ngdc.noaa.gov/geomag-web/#declination and enter your info in the left. Then use the right side to get your Declination. NOTE: make sure that you enter a "-" in front of your value if you are in the "east".
You can still use a external mag should you want to... just follow the wiki on how to do that.
Q2.
I don't think that there is a "log" as such for crashes. All said and done if you follow the wiki on setup and TAKE YOUR TIME, you shouldn't crash.
When you go out for your first flights stay in Stable mode until you are good with it. Then go to either Loiter or Alt Hold. make sure the PID's are good for your setup. From what I have been told these two modes set everything else up. So if your not good with these don't try something else (ie RTL, Way points, etc).
Good Luck!
