All,I have an APM2.5+ w/ enclosure (allows vertical adaptors) that i would like to sell. I found out recently that my 3.3V regulator was blown and I do not want to attempt to open it up and fix this. This was purchased directly from 3drobotics in…

"Crady,
  Clearly what I thought was the correct way to install the props was backwards.  I thought the "R" was for counter-clockwise side.  I swapped the props and am getting thrust!!  Thank you SO much.  Time to continue testing."

"Just ran a test:

50% throttle current draw (1505 PWM): 9;06V @ 37A
100% throttle current draw (1891 PWM): 8.3V @ 52A - 60A

I see FAILSAFE on my HUD.   All my Failsafe is disabled.

"Max - Sorry to hear about your issue with the brand new APM. I got my APM2.5 a year or so ago directly from 3DR Robotics. I didnt have a Bad Gyro Health issue until updating to 3.1.2. I think that the blown regulator did not cause any problems for…"

"Thanks guys.. I will try and power my RX independently of the APM, ESCs, and Motors and see if I get similar results or if I am able to get results closer to the Wiki.  Thanks!"

"I was able to find this article about a blown 3.3V regulator. Although it provides some ways that the regulator can burn out, I didnt think that I did any of those.

"Update: Learned that the ATMEGA32U2 may be a special PPM encoder Chip.  I will use A0 to A3 (pin 97 to94) as my inputs from my Radio RX outputs instead.  Still not seeing what I would expect for PulseIn command.  All power is applied correctly.…"
