"Just saw this at Hobby King and started to think.. would this be helpful in supplying a stable power supply to the APM2?
just curious.. also could it hurt anything to plug this into the output rail just to see? the specs…"

I received my APM 2.0 a couple of months ago. On my maiden flight, I was having some trouble flying in stabilize mode. I switched back to manual, and the plane promptly went belly up and straight…Continue

Sorry for jumping in the middle with a different problem and setup:
A very dangerous bug:
From time to time during automatic takeoff, the plane (not multirotor) became unstable and the “ball” looks very chaotic wail the plane is not…"

Andre replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"@Brian
Did you fly with std settings with the Rtl and auto flights"
Brian Mahaney replied to Richard's discussion APM2 damaged in crash"i bent the pins on mine also (also a brown out problem). i carefully straightened them with needlenose pliers. i've had no problems since."
Anthony Dao replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"I ordered another one, but I think the MUX got damaged based on other discussions. I plan to rework the board, I will order a new MUX and mount it to see if that fixes the problem. I already reloaded the firmware via the ISP to the ATMEGA32U2, but…"
"The processor is rated 5.5vdc max. It has been stated anything over 6vdc will damage the board. 12vdc on a 6vdc max board should destroy it. Sorry. Nothing another $200 should't fix."
Anthony Dao replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"This is good news. APM2 is awesome and of course diydrones.com."
Brian Mahaney replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"UPDATE: I flew again this morning. I tested auto. I found that my problem last night was that auto was set to different switch setting than I thought. The plane hit all the waypoints beautifully. I'm a very happy…"
Brian Mahaney replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"I had a mostly successful flight this evening. after changing the esc, I did some testing on the bench. there were no problems so I decided to try some flight testing. Rtl worked flawlessly. Same with stabilize. That was my intended test for…"
Anthony Dao replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"I didn't solder all the pins on the GPS board to the APM. So that may have caused the problem.
Bad news now. While trying to diagnosis the problem I hooked a power supply with 12 v to output rail (I meant to set it to the recommend 5.3V +/-…"
Brian Mahaney replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"I switched the esc. this seems to have solved the problem. thank you.

"Sounds like a brownout. Move to a higher capacity BEC."
Anthony Dao replied to Brian Mahaney's discussion APM 2.0 lock-up causes crash?"I have the same issue. The lockup can happen in manual or stabilize mode. I can duplicate the problem by rocking the board back and forth when I'm testing on the workbench. It would freeze up and then a minute later or something it will return…"
Brian Mahaney posted a discussionAPM 2.0 lock-up causes crash?
I received my APM 2.0 a couple of months ago. On my maiden flight, I was having some trouble flying in stabilize mode. I switched back to manual, and the plane promptly went belly up and straight into the ground. I built a new airframe and began testing some things the other day. I found that, while in stabilize mode, the whole system will lock up for 2-3 seconds when I manually activate the control surfaces. Sometimes, when I put it back in manual mode, the left aileron will shoot…See More
Brian Mahaney replied to entropia666's discussion JP1 connection not present in my board"If it were me, I would probably solder some pins and put a jumper on myself. I'm reasonably comfortable soldering, but you may want to check with customer service first to see if they can help. It looks like a manufacturing error to…"
