After 2 weeks of building, reading and testing, I took my quad out for its first flight today. I hated every minute of it. I had flight modes set set to Stabilize on all three positions on the…Continue
"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.
"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.
The Mediatek GPS has an…"
"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…"
"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…"
"Damn, what a hell of a ride, thank god the problem has been sorted out for you!!! Hopefully the repairs are not too expensive.
BTW: I programmed my Frsky RX to give the following command to APM on signal loss: Flightmode: RTL, Ail/Ele/Yaw Sticks…"
"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…"
"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…"
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."
