"A cold start to full fix (inlcuding having the entire almanac) should take no more than 14 minutes. I doubt that it is a problem with insufficient power, but you could try this by powering them from a USB hub that has an external power supply.

Nicolas replied to Edgar Scott's discussion GPS too good to be true? in the group ArduCopter User Group"It takes roughly 12 minutes to download the almanac from the satellites, and a few seconds to download the ephemera from the satellites that are within sight. The almanac is usually valid for a few weeks.

Nicolas replied to Darrell Burkey's discussion Failsafe on Spektrum DX6i in the group ArduCopter User Group"I have a Spektrum DX7s with AR8000 receiver, so my knowledge applies to this pair - and should hopefully apply to yours.
Out of the box, my TX had a lower limit of around 1100 PWM - as confirmed in the APM Planner. One of the RX/TX failesafe…"

Nicolas replied to Marque Cornblatt's discussion Using an Extra Channel to Trigger a Servo on a Hexa in the group ArduCopter User Group"I have the same radio (and not much experience with it) and found that most of the additional switches aren't used by default, other than:
Chan 5: Gear - 2 way - top, left.
Chan 6: Flaps - 3 way - top, left
Chan 7: AUX Pot.
Why not use…"

"Wow. That quad really wanted to get out and see the world.
I know most of the settings are tempting, but the defaults are where you want to be for the features. I've never used failsafe in two years of standard flying and I doubt I will unless…"
Nicolas replied to Nicolas's discussion My first flight and first crash: Flight mode switching between stabilize and RTL."And I was nudging it with an high throttle, so it was doing exactly what I was asking it to do. Except, not what I was intending. Ah, the trials and tribulations. Thank you kind sir."
Nicolas replied to Nicolas's discussion My first flight and first crash: Flight mode switching between stabilize and RTL."I will do that, thank you. I believe the receiver can (AR8000)."
Nicolas replied to Nicolas's discussion My first flight and first crash: Flight mode switching between stabilize and RTL."The spinning was me, I was panicking at the height gain, and trying to disarm in-flight. The wobbling movement was me gaining some control, then trying to determine orientation. At just under half-a-kilometer, I couldn't tell which was forward…"
DeveloperOlivier ADLER replied to Nicolas's discussion My first flight and first crash: Flight mode switching between stabilize and RTL.
"
You don't need the throttle failsafe if you can program a failsafe on your receiver channel 5.
You can just program a failsafe on channel 5 to trig RTL mode, and disable throttle failsafe. This is simpler."
