"Just tried powering the APM from one of the ESC's and there is no problem with the APM when doing it that way.  Seems that it was the Power Module that took the hit."

"You should try powering your APM via one of the BEC off one of ESC. You will power through the output pins. Remember to replace JP1 jumper."

"@Steve, You gotta remember the old saying "Measure twice, cut once". I did the same thing during the testing of my Maja drone when I bypassed the normal battery cables and incorrectly hooked a spare battery directly into the CC Phoenix ICE…"

"Yes I had the +5v from the PDB connected to the APM 2.5 as well as having the PM connected and all works fine. "

"I just setup my Quad using the PM and i did not put the JP1 jumper in i left all the other connections in place as they were and the Quad performs fine.  It real should say if using the PM do not use the JP1 jumper. I also tried it without…"

"I just had the same type problem and i re-calibrated the radio using the mission planner and all is working fine now."

"I have one on my desk, but having trouble with the boot loader due to my PC having Win7x64, which, unfortunately is a known issue... will have to dig up an old system from the archives. Keep us posted on your progress"

"I have one of these going into a new custom build presently... as it's an advanced research platform it's got a lot of other bits to go into it before flight tests... but I'll report back in Jan/Feb as to our experiences with this FMU…"

"Thanks to everyone for the help i have the Quad up and running ! I ended up finding Mission Planner 1.2.15 that i had a copy of and used it to load the Quad and the Parameter file to the Quad. So right now i have a Quad that can be flown i plan to…"

"Here is an older version some members are running, and it is the only one I can find on short notice that I know will fit on your board. I don't have much experience with the older boards, and loading the firmware file I'm afraid. The…"

"there is also this thread which should help///"

"You can still load an older version of the code and it will work great, you just won't be able to get any of the more recent updates. IF that doesnt matter to you then Im we can rundown a copy of the firmware that will fit on that board that…"

"So ... the bad news. The 1280-based APM was depreciated a very long time ago. Years, you might say. However, some kind developers have, for much of that time, hacked apart the code to reduce it down so it fits into the 1280. I believe that has…"

"My Quad frame is a replacement for my old original ArduCopter frame i decided to upgrade it to a newer version of the frame. I have flown the old one many times but wanted something that was a bit newer. My autopilot is the original APM 1 with the…"

"One more tip: be very gentle with your USB connector. They are easy to break away from the board. If that happens, there are solutions, just ask me, but better to avoid it."

"Short answer is, even if it is already built, start here: http://code.google.com/p/arducopter/wiki/ArduCopter2Quick Read everything, if the step is already done, look over the work and pretend that you are doing it. Only once you understand it,…"
