"I will need to do some research into how to obtain the logs. But I will definitely try my best. Would like to know what went wrong. 
We are building a frame that is 1150mm from motor to motor, measured diagonally. We hope to get some good stability,…"

"Hi. I know its been a while, but like you said, deadlines get you going.
I have gotten the copter functioning by remote, completely, land function and all. The autopilot worked once, and then the next time I tried a flight, I armed and it took off…"

"Hate to revive this thread, but I need some help. The 3DR Tech help said (like what was mentioned before on here) that the Power Module couldnt handle the 6S battery we were using. Well we bought an AttoPilot 180A to eliminate that problem. i wired…"

"We do have all of the motors turning correctly. First thing we did when we started. Only one was wrong, so switched the wires.

Thanks,

"Also, why do I have to run the initial setup wizard every time I charge up the Arducopter? Its like it doesnt recognize my radio and I have to rerun the wizard. "

"Two of the props are CW two are CCW. They are mounted diagonal, i.e. one CW is back-left, the other is front-right. 
We have no power distribution board. Just the 3DR power module, and the battery that is running 5 cells. 
What is it that yall were…"

"The ESCs, props, and motors are all the exact same. I have no pictures of props, but they are 12 inch carbon fiber, the ESCs are Hobbywing Platinum Pro 40A, and the motors are Navigator Series T-Motors. I dont know anything more about the motors…"

"Yes it does do it. I went ahead and started calibrating things after I read some other information on the Wiki. When I put the throttle on and tilt the copter, you can actually hear the motors on the side going down reving up. Id say thats a good…"

Hi. My EAST program is working on building an ArduCopter as our big project this year. We have the frame up, but now are starting to run into issues. I have all the battery connections hooked up well, the ESCs all connected properly, and the Futaba…

Christopher Stephens replied to Christopher Stephens's discussion Help with charging ArduCopter...
"Well, I kinda thought that. Our ArduCopter battery seemed to charge though. Im not sure why, but I think it could have something to do with the fact that the battery is 6 cell. Wouldnt the charger charge and balance each cell one by one and balance…"

"Ok another question: I modded a computer power supply to use as an input for the charger. It is cranking out 12.5 volts. This works for the charger, but will a 22.2 volt battery charge off of only a 12 volt power?"
