I rarely allow my
MM2 to reach a low battery level where the drone decides to land itself.
Before starting a flight, I generally check the failsafe procedure for loss of signal or low battery on the
MM2.
Yesterday I faced a low battery warning, "Low battery. Return to home promptly".
I was within 35 meters at 3.0 meters height and 20% battery. So no need to panic.
Next warning is "Low battery. Aircraft will return to home after countdown."
Once the 10 second countdown is over, "Low battery. Returning to home". (still had 18%)
So the
MM2 landed, no stress as all my flying was close and at low altitude.
One reason I got the
MM2 was due to the fact that large cities usually have controlled class "C" airspace, and anything over 250g needs permission to fly.
So the
MM2 gets a lot of use and the
M2Z doesn't go up very often.
Which led me to fire up the
M2Z once I cleared Class C airspace.
If others who own the
MM2 as well as larger drones such as the
M2Z, and find that they don't use the
M2Z very often, it's a good idea to make a thorough review of all flight parameters before sending the
M2Z up after a few weeks of not flying it.
This is especially important if an update to the firmware has taken place, as it may automatically reset some key parameters. such as RTH settings.
The
MM2 and the
M2Z have different menus for an event such as a loss of signal.
The
MM2 allows the pilot to RTH, hover or land.
I looked on the
M2Z and could not find a similar option.
Maybe I missed something, since I was looking for a menu where I could instruct the drone to RTH in case of loss of signal.
Is there a similar menu to make sure that lost signal defaults to automatic RTH?
I have read page 15 of the
M2Z user manual and it seems as though the RTH will give the option to automatically RTH along its original flight path.
There is Smart RTH (Pilot taps "home" button)
There is Low Battery RTH (automatic RTH initiated by a/c when battery reaches set point)
There is Failsafe RTH (automatic RTH on loss of signal).
What is Emergency RTH and how it is different from Failsafe RTH?
(this term is only found in the tables on page 16-17).
