Im sorry but auto land just sounds like a bad idea lol.
Im sure in concept it sounds good but I personally would rather be in control during a landing.
with practice both a hand catch and a ground land are fairly easy.
In all situations never use CSC to turn off your drone.
Yes they do.
There was someone on here that posted the RPM(s) with the props on and with the props off and they sped up quite considerably with no props on.
I will see if I can find that post again.
A couple things wrong with your response DeeX.
You are in control during an auto land. You can move the P3 around with the right sick (mode 2) and can slow, halt and even climb during an auto land searching for a suitable spot to set it down. The left "throttle" stick switches to 3/4 to hover, 50% to descend. Above 3/4 stick, the P3 will climb.
2nd about the motors over revving without propellers attached. They don't. What does happen when running the motors without props is the motors can overheat rather quickly without the cooling air provided by the props.
Hope this clears things up a bit.
