Thank you 3DR customer support for the timely and professional job of repairing my APM 2.  It turns out that I had a bad diode on the board D1 and was able to send it back, get it repaired and returned, all in just over 2 weeks. They even sent me an…

Hi all,I'm reposting this discussion hoping to get a response.  I uploaded 2.5.5 after erasing eeprom on APM2, and when I went to the radio calibration screen, the Yaw "bar" value was at 1640 (off center to the right) without any inputs from my TX.…

Hi all,I've successfully loaded and launched the flight simulator in Mission Planner.  Now, how do I use it with my TX?  Do I need to plug my APM board through usb into the computer and turn on my TX.  Do I need to arm the motors?  Is there a start…

James Dinh replied to Patrick Dudley's discussion Searching for decent motor mounts
"The motor mounts that come with the RC Timer motors are a bit soft, but if you mount them in this way here it should be fine. You can't see it on the video, but I put neoprene rubber washers from Home Depot here between the frame and the X-mount.…"

Hi everyone,I have a 4S 5000mAh battery on my hexacopter.  What is the lowest safe voltage per cell before I risk losing power to my motors.  I want to know in order to set the value on my battery low voltage alarm.  Also is there a way to program…

"Hi Vernon,
I have APM 2.  Everything worked great, flying great.  Then, I had a crash.  My fault, not the board.  I crashed into a tree.  Now, the board lights up fine when I plug it in via USB to my computer.  All the LED lights show normal…"

James Dinh replied to James Dinh's discussion Please help! Board does not turn on.
"If no one can suggest a good fix for the problem above, I might have a solution that may work:
Since the board can be powered by the USB port, I can use this 5000mAh battery with USB port here and connect this to the board via USB.  Since USB is 5V…"

James Dinh replied to James Dinh's discussion In Theory, some say my Hexacopter can't get it up!
"Thanks,
So far I've clocked it at about 25 minutes (hovering only) drawing only 3500mAh of each battery.  I think I can safely stretch it to 30 minutes if not longer.  But actual flying with additional throttle and pitch and roll will be less.  I…"

"Sounds great!  I suggest isolating the boom from the main frame with some sort of anti-vibe bushing or grommet, especially if you are going to be doing any kind of aerial photography. I have isolation rubber grommets on mine, and have noticed…"

"If your quad is pitching back or forward during take off, it could be that your leveling is not accurate.  Use a level that has a bubble for accuracy, and check.  Make any adjustments to your quad to permanently adjust for the new level.  Then redo…"
