"Chris, many thanks, thats all i needed to know !!!    Gil"

"It's plug and play. This is all in the manual."

"right, so if i purchase the one you mentioned, does it need to be configured (code) or it is just plug & play on the APM2 and set it up within the planner ?  thanks"

"APM 2 doesn't require a sonar/ultrasonic sensor at all. It has a state-of-the-art pressure sensor that can handle altitude hold fine by itself. The only reason to use a sonar sensor is if you want high-precision autolanding. In that case, we…"

"Hi Chris, can you confirm this sensor to be the most suitable for use with APM2 board with multicopter configuration ? I need to order one but still don´t know wich one to choose !    thanks in advance.    "

"Would it be possible to get the DXF files for this mount uploaded to your svn directory so that we may cut this out???   Thanks"

"Would you mind passing along your gain values for everything,,,,,I am seeing an okay performance, its stable but not like some other videos..."

"I have one in a SkyWalker, which is similar to the 168 but foam instead of fiberglass. I see no issue with installing one in a 168. In fact I'll probably do so if the 168 ever comes back in stock...."

"Dean, well trust me.. it works. All 4 are in use. Also if you want to move LED's away from OUT4-7 to their "correct" location you need to modify ArduUser.h file   /* AM PIN Definitions *//* Will be moved in future to AN extension…"

"Well, sort of. The only thing I see in the code turns on OUT7 when the motors are armed. //#define IsAM        // Do we have motormount LED's. AM = Atraction Mode if (motorArmed == 1) {   #ifdef…"

"Just looked latest code and it seems that there are OUT4-7 already defined as default output ports. So just activate #define IsAM from ArducopterNG.pde and you will have working LED output."

"I would agree..I have the same issue with yaw kicking in and trying to correct immediately on the ground right after arming, and again in the other direction when disarming...I am coding the same issue..."

"Oh ok I was wondering the same thing.  I spent an evening looking at every photo I could find of the frame thinking my arms were defective.  I haven't checked the assembly manual recently but last time I checked (few weeks ago) the…"

"I think Jani took those out by popular request because nobody was using them and they weakened the arms at those points."
