Matthew Gray replied to Franco Nogarin's discussion Help with Tuning AC2
"Please help with PID's. Someone has got to explain more simple and thorough how to adjust these parameters. The wikipedia info is just confusing. My problem is my hexa oscillates like crazy. My stabilize kD values are all at 0. Should I go negative…"

Matthew Gray replied to Gordon's discussion Hexa plus configuration
"Yes I did the same thing. hexa+ and it seemed to work. I changed to hexa in x mode and the motors are working now. The PID's are out of wack though. On stock PID's I almost crashed because of so much oscillation."

I have gone through setup and set my frame to hexa+When I arm the motors only 4 motors spin. The front and back motors do not spin. Also, when I tilt the copter I was expecting the motors to attempt to level the copter which they did not do. Help…

Matthew Gray replied to Gordon's discussion Hexa plus configuration
"I'm doing the same thing. I'm assuming it's the same as ardupirates with motor 6-7 in front.

Right now It's not working correctly for me. I setup the frame as HEXA+ but when I arm the…"

Matthew Gray replied to Nigel's discussion Latest beta not working at all? (as at 9th May 2011)
"I can't get it to work either. Initially The code appeared to load and I had some cli function, but I could never make it totally through the setup.  I tried to relay the code and now nothing works."

Is there a guide on how to use the arducopter configurator? Just some simple definitions would help really. What is kp rate? What does it affect? When I change the PID settings, how does that affect the copter?

Matthew Gray replied to Matthew Gray's discussion Ardupirates Hexacopter Questions
"Also, in the configurator it said to move my aux 1 and 2 end points to 50%. I just figured out that when i did this I could not disengage the yellow led on the imu board. I moved the end points back to 100% and now i can get the yellow light to go…"

I'm building a hexacopter with ArdupiratesNG code downloaded from Tortoise SVN. My equipment is a Ardupilot Mega 1280, ArduPilot Mega IMU Shield/OilPan Rev-H V1.0, RCtimer motors and ESC's, Futaba 2.4 Ghz 7channel radio. Problems: It appears as…

Matthew Gray replied to Owen Booth's discussion I can't even arm the motors!
"Im also having this problem. When I put the slider switch on the apm board towards the front it doesn't connect. When i put it towards the back it will connect but nothing else will work. Does this happen to you too?"
