"Hey dmac, i know how it feels, being raining here too. About the PIDs, as i can see from your design, it looks like you should be safe with the default values, fly with the defaults, and remember, watch how it flies, i even find it useful to record…"

"its for + configuration, but the principle is the same for X, in X if you pitch the copter down, both front motors should start spinning, or if you move the pitch stick forward, the 2 back motors should spin, in general, the motors that are below…"

sam d replied to Max Xam's discussion yaw problem
"I guess its because of the compass, but im not 100% sure, someone else can confirm it. As far as i know, the quad is not able to know its direction accurately without the compass (gyros are not good enough because of…"

sam d replied to F5PQL's discussion Setup + vs Setup X
"also, X frame has less width while navigating forward than + setup. If you fly in narrow places, you may call that advantage.

sam d replied to Michael Brown's discussion ArduCopter with Mission Planner problems
"In the IMU test, it should definitely not change that much when not moving the quad (at least while not moving the quad/APM), but it is normal behavior when moving the quad/APM shield.
At least, thats my case, just after leveling (i did a…"

sam d replied to valentin colon's discussion PID tune
"looking at  the mission planner screenshot in http://code.google.com/p/arducopter/wiki/AC2_Tweaks
 GPS position hold related PIDs would be:
     * Loiter Lat PID  (for latitude)
     * Loiter Long PID (for longitude)
 Altitude hold related PIDs…"

Hi, is it safe to plug in the lipo battery while i have my APM connected through USB to the computer? The reason i want to make this is to stop unpluging BESC power from the apm and connecting it to the receiver (and disconnect radio power lines to…
