Ben Cairns replied to Edgar Scott's discussion Does the APM really have to be in the very center of quad? in ArduCopter User Group
"may affect the roll/yaw as the rotations will be slightly greater one way, so it may "bounce" on those axis, but pitch should be unaffected"

Ben Cairns replied to Pascal06's discussion Little Flip in ArduCopter User Group
"I haven't looked at the tlogs yet, but from the video it looks as though one of the motors is dipping.
I had this a couple of times with my quad;
I use an f450 frame with NTM 2816 (1200kV) motors, controlled by Turnigy TY-P1 25a ESCs
The Motors all…"

Ben Cairns replied to Austin Laws's discussion APM2.5 Firmware version 3.0.1 PID tuning in ArduCopter User Group
"Looks unlikely to be Barometer.
With you saying loiter is poor is suggest running a compassmot setup. You will need a power module to get this 100% though. They're a great investment if you haven't already got one. Oh and balance the props"

Ben Cairns replied to Austin Laws's discussion APM2.5 firmware version 3.0.1 Quadcopter in ArduCopter User Group
"Auto trim:
Hold the rudder to the usual arming position, but not for the normal 4 seconds, you need to hold it for about (I think) 20-30 seconds. You will notice the A/B/C lights will start to flash in a different sequence. Take off, and give stick…"

Ben Cairns replied to Darren Woodhouse's discussion Arducopter 2.6 on TBS Discovery in ArduCopter User Group
"Hi, 
The other frame option (I think its called V - Sorry not in MP now so can't be sure) is more suited to any frame that is not either a '+', 'x' or Hex/Oct.
It was designed with these frames in mind, and has a slightly different tuning to allow…"

Ben Cairns replied to Daniel Estes's discussion APM Mode Values in ArduCopter User Group
"I try and get mine to be at the halfway point between the values. I know my Rx will drift a little (usually +/-3-5) so I NEVER go anywhere near the end points of the PWM modes. too Risky!I don't want my craft going into an Auto if its battery is…"

Ben Cairns replied to Loren Zimmer's discussion My first setup...looking for critiques on layout in ArduCopter User Group
"Compassmot is a way of programing the apm to compensate for magnetic interference from the wiring,  motors, escs etc. It measures the interference and then can use this to ensure it knows which way is North. If you fly eith gps you week find this…"

Ben Cairns replied to Loren Zimmer's discussion My first setup...looking for critiques on layout in ArduCopter User Group
"Looks good, You could get the ESC's futher away from the APM, and look at removing the red lead from all but one esc (Saves on paralleling the ESC's. This can be bad for the APM.
Remember to run a compassmot if you're using FW V3+"
