Automatic shutdown of the propellers

[EnricoBrun]

I'm looking for but I can not find anything to wrinkle ... there is no way to keep the propellers at the minimum speed instead of automatically turning them off at each landing? Thx

 

[old man mavic]

why would you want that feature they stop for safety and you can start them by using the sticks without the UAV taking off

 

[CanadaDrone]

Not as far as I know - I can't think of a reason you would want that and most of the reasons have to do with safety. You can always start them again into an idle state seconds later if you like.

If you've come in for a landing and want to fly again, you should be using a fresh battery anyway - never start a new flight without a 100% battery that has been freshly charged.

 

[Kilrah]

Why would you want that?

If you disable Landing Protection you can kinda get it... until integral wind-up starts throwing the thing around because aircraft with constant height control like this one are not meant for it.

 

[EnricoBrun]

I was pleased to know if it was possible not to turn off the propellers and then start again "touch and go" maybe when you show friends take off landing ... without having to restart the engines ... all here

 

[old man mavic]

no worries EnricoBrun it just seemed a strange request i guess the only thing to do is get a small drone with no gps or alltitude hold then you could do touch and goes possibly

you can do that with a phantom

I was interested in your reply Not because of thesubject matter but by the fact that you said one should never start Flying with a partly used battery. I thought it was wrong to just use say 10%/ 15% of the battery and then recharge it. I thought it was better to run the battery down to about 40% ( at this level I think RC will show the battery as being down to 10%) . I know That lithium ion batteries don’t have the same memory problem as the nickel cadmium batteries But I thought it was better for the battery to run them down. Obviously I wouldn’t use batteries below 40% charge.
DJI recommends That the batteries should be discharged regularly!

And Inspire series

You might need to upgrade to Hot Dog

You should always begin your flights with freshly charged (100%) batteries - this ensures voltage is correct and that it interfaces with the drone properly. It's just best practice and gives you a cushion in case you run into unforeseen conditions as well.

For long term storage, you will want to leave them around 40-60% (they discharge automatically to this level if you put them away at 100%). A charge cycle every 3 months is also best practice if they are in long term storage.

Lithium batteries don't have a memory, so you can charge them from 80% to 100% if you're going to use it right away and you won't be doing any harm.

Lithium batteries don't like heat, they don't like sitting at 100% for a long time, and they don't like sitting a a very low percentage for a long time. Frequent charges are totally fine expecially if you use it right away and it's not sitting at 100% for the maximum duration before they auto-discharge to 60%. It's also best if you wait a few minutes for a used battery to cool down before popping it right on the charger, as they come off the drone very hot, especially if you're flying in hot areas.

In an ideal world, like with your smartphone for example, keeping the battery between roughly 30% and 70% at all times wold be the best thing to do, but it's not practical.

I end all my flights at 30%, so it's usually in the mid-high 20% range when I land. Once the batteries cool down I charge them up again either to 100% if I'm going to use them, or to about 60% if I'm going to store them.

 

[DanMan32]

If you haven't powered off the AC, then there shouldn't be a problem landing at say 50%, then taking off again. App, AC and battery firmware should be using same charge reference as when it was powered up and launched at around 100%.

Since we're off topic, I am curious about the battery keeping track of how many times its been charged. If I only run it down to 40% and recharge it, it's not really been used as much as the number of re-charges would imply. Does the battery have a certain number programmed into it before it decides you need a new one?

I am curious myself about landing without shutting down the props completely and then taking off again. I'm sure I could think of a few reason why I would like to do this but the first that comes to mind is that if I land somewhere besides the "Home" point and then take off again it saves that spot as the new "Home" point. I'd rather it kept the original

In fact it would be nice that with an option selectable by the pilot that, when the drone touches the ground instead of turning off the engines put them at idle speed and then with the throttle then return to take off!

You can re-set the home point anytime you want if the device you're flying with has GPS.

I'm not sure I understand how to re-set the home point to the original home point once I have landed somewhere else. Please elaborate!

You can set the home point to wherever you (and the remote) are, the function is called "Dynamic Home Point". I don't think you can change it back to a previously recorded home point, but presumably you would always want the home point to be where you are standing.

All you have to do is use RTH button once the aircraft starts to come back stop the RTH and you can now land without stopping the props but please be aware that it will now come down fast and hit the ground if your not careful because landing protection gets disabled after you hit RTH

I don't believe you understood the original question.

What we would like to be able to do is fly out and land at mulitple locations and then when we hit the RTH the AC return to the original launch spot or at least give us the option to select which of the last X number of landing locations we'd like to RTH to.
