Has DJI allowed greater tilt angle for RTH?

I can't follow that. It is getting late I guess. I respect your opinion in any case but I'm not sure what that is ;-) Fly well.

Edit: I think I hear you. But you are saying its about the mechanism of the hobby not the enjoyment, is that right? i don't agree with that. I am well prepared and havent lost one yet. I just think that these can be better. My father mastered Rc helis in his 80's and that was no easy feat. But I know he would be much more delighted to fly one of these drones if he were still alive....even though they are much improved ;-)

I understand. It's a good opinion though. I just think how some people see it is like drinking and driving which ends up some people being done with life and driving on the wrong side of the road leading to a demise. I see things too far but it's just nice to correct and expose certain vulnerabilities whenever possible. I assume you know what conditions are possible to fly like some business owners who never go bankrupt but there will be those who will try to be an entrepreneur lacking certain key things and them losing everything and more. It's something so simple as adding more tilt angle and nothing else but I like to extrapolate the very small insignificant seeds as far as I can to exercise my own ability of being knowledgable.

Flying super fast on a DIY quadcopter at 100mph is more of a release than flying the Mini. If you want more of a release with a DJI drone get a better one. Saying "poor" isn't entirely poor. It's just not allocating the resources because of some sort of emotional boundary which prevents other issues from growing in the mind. Being truly poor is not being able to afford the very basics.

It's a very dangerous hobby. If it wasn't, then the FAA wouldn't even care. Nobody would. Knitting is not dangerous. I feel the same way about motorcycle riding at times saying how it's "not dangerous". I ride w/ shorts on in the summer.

I used to compete in competive archery at a college level using very sharp broadheads. That was mildly dangerous. This is not IMO. Get real, if you don't deliberately buzz folks, it's not problem. Cue vets to argue as they do.

It's just showing the new people who aren't as knowledgable as something that is dangerous as not dangerous. We can say it's not dangerous as it's easy for us but we shouldn't give a bad impression into thinking it's nothing.

I'm not saying don't do say 150mph, I'm saying you can as long as you have everything else checked and done right or at least enough. There were times when I was ready to go but right before I was going to go fast I lost control by getting shaken up w/o totaling. I was ready to ride very fast in the wet. but did a quick almost high-side in 3rd gear on the R6. From that moment, I save going very fast when it's dry. : ) Not everybody made it in the motorcycle hobby. Should we just smile and forget about everybody else?

I have to admit I've seen threads taking off on a tangent, but this one is setting a new record... I have trouble understanding what's being discussed, at this point...

I think it makes sense to increase the RTH max tilt for reasons I have explained, but I think people are reading WAY too much into it, in all directions (in favor or against it). It's a small tweak to get the MM to RTH in marginally stronger winds: agree, disagree... but that's it, that's all.

Counter arguments are not logical.
Mavic Mini can already increase it's tilt angle, thus speed as proven by Mavic Mini having Sports mode.

One possible counter argument was Mavic Mini did not have processing power to do obstacle avoidance at it's maximum speed (aka Sports mode), but specs for Mavic Mini removed counter argument.

No one has come up with a legitimate reason why DJI can not make a minor firmware change allowing Mavic Mini to RTH at increased tilt angle (aka Sports mode) to battle head winds.

It has been explained many times but some folks choose not to listen.

To be fair, all that was “explained” was why some people don’t want DJI to. There was no technical argument provided why DJI couldn’t do that.

Just out of curiosity, an honest question: for the sake of argument, suppose tomorrow we get a new firmware and fly app. And lo and behold, we get a new option named “switch to S mode in RTH if strong wind detected”. Are you honestly saying you will leave that option off?

We often talk about "speed" when it comes to RTH, but to be precise my ask is about tilt.

It seems there are two parameters related to RTH in the firmware, max tilt angle and max speed. The former controls the airspeed, the latter limits the ground speed (as that's the only speed DJI drones can measure, via GPS). I don't want the MM to have a higher ground speed during Failsafe RTH, the current 8m/s (assuming that's really the limit) is perfectly fine. I'm simply asking for the MM to have a slightly higher airspeed (= higher max tilt) so it can make better progress against headwinds.

There is no one here that doesn’t want dji to change anything, if dji feel the need to change for the better then that’s great for everyone.
But the problem with this ridiculous proposal is there is absolute no proof that any more drones would be saved by increasing the speed of Mavic mini to the highest speed of any dji drone in Rth mode.
And you certainly haven’t proved it would.
All increasing speed of Rth will do is allow users to use mini in higher winds than any other dji drone thus creating exactly the same scenario, that new users and those who can’t be bothered will stretch the limits again.
I have seen less than 5 mini drones lost to the wind because of lost signal in winds to high, yes 5, I know of many more Mavic pros lost to the wind because of loss of signal and wind to strong, I know of Mavic air which has increased pitch in high wind, which automatically turns off OA to increase pitch and speed, also lost to winds to strong.

I believe one of the reasons dji would not allow for this is simply you would now have a drone in Rth now in sport mode no longer under control of the user and secondly stretching the boundaries will safe diddly squat, and I think much better to educate the 5 who lost their drones instead of trying to appease the mistakes they made and lead them into some ridiculous falsehoods.

It’s not just a coincidence that all of those who lost their drones through loosing signal were new users.
Your making an argument for a minute amount of people, it’s pointless it’s not going to happen and it’s a really a nonsensical idea, with almost no benefits for anyone .

I don't know what are the RTH parameters for the other DJI drones: they might have the same RTH max speed of the MM, but they might be allowed much greater tilt angles, thus being able to fight much stronger headwinds. As I explained above, I don't really care about the max speed, I simply want more tilt.
Speaking of which, the MM seems to be limited to 20 degrees, but I was not able to confirm that. I tried to, looking at a flyaway log someone posted here, but while the tilt angle was primarily around 20 during RTH, at times it was higher and lower (for extended periods of time) for no apparent reason.

Geebax

I would imagine that historically DJI have limited the speed of the aircraft in RTH in order to conserve battery power, which is a sound decision, probably on the basis that is is better to return slowly rather than not at all. But if the headwind is too strong, then it is a moot point, because it still may not make it home even if the speed is increased. The trouble with trhe Mini is that it has such poor performance against the wind that either way it is probably going to run out of battery power before it gets home. So why not increase the speed to Sport mode so it runs out of battery and drops into the water (that most Mini flyers seem keen to fly over) or falls out of the sky randomly, which the Mini is equallly capable of.

Ice_2k

Dirty Bird Posted at 3-20 13:32
As I have said repeatedly, I don't see DJI complicating things with a variable-stage RTH protocol for the Mini. RTH is going to be at a single set speed, just like it is with all the other models. I can see increasing the Mini's RTH speed to 22 mph so it matches the other birds. I don't see, nor support, it being bumped up to 100% maximum possible speed.

That was not the question

I would be almost certain that tilt angles for Mavic mini where engineered by pretty good dji engineers and I’m certain they didn’t just throw mini together without any thought of how it would fly in environments they recommend.

What your looking for will not save any drone from being lost, we know this because from large to small drones , some have been lost to the wind, but by far the majority where lost by beginners and I would say that this is close to 100% for mini users.

I believe that a simple thread that explains the safe use of mini would save a lot more drones than what is being discussed here ad nauseam .

Neither speed nor tilt will save any mini and I’m thinking it’s more likely it will cause more to be lost, one thing we know for certain is if you fly in the right conditions in the right environment then you’re not likely to lose your drone, you will have much better footage/photo less stressful flights particularly for new users.

As I said in above post the amount of drones loosing signal and just happen to be in wind to strong and getting lost is extremely few.
In all other circumstances of Rth you have full control of pitch tilt and speed .

The mini is a good little drone with some great features for photography, I believe it’s for new users but these new users need to respect its limits, ( they won’t change) and if they do they have something that’s easy to manage takes really good footage and is a good stepping stone to other drones.
I believe your argument is futile and would be better spent advising others best practice and how to enjoy what they’ve got.

I see yourself, ice, Who say you don’t need this and Ant who frankly doesn’t give a sh#t and Hedgetrimmer who doesn’t even own a mini, making all the noise about this, but no one here who has actually made the argument they lost the drone because at certain tilt or speed of 22mph as opposed to 18mph would have saved their drone is a bit ironic .

Real problem might be Mini's descending without input, now that's a worthwhile thread!!!!!!

The only reason why I added a couple posts today was to highlight the difference between max tilt and max speed, and to clarify I was talking about the former. I thought it was important, especially if we are comparing the MM to other DJI drones.

I don't question that most MM got lost in the wind by beginners because of mistakes they made, due to lack of knowledge. If you have control, simply pushing on the right stick during RTH will achieve what we're asking, and it could make the difference between losing the AC or bringing it back home. But that's exactly the point: if a skilled pilot can do it, why not doing it automatically, and prevent those beginners from losing a drone?

120ccpm

Dirty Bird Posted at 3-20 13:48
The issue is, even at the same maximum angle of attack, the Mini has less mass & is limited by smaller motors, props, lower voltage, & less available thrust than all the other models. No matter what is changed the Mini is simply less capable to cope with strong wind.

No question that the MM is less capable of other drones, not much because of its mass (if anything, less weight is a positive thing, no?) but because of its limited thrust. But we also know it's capable of more than 20 degrees (assuming this is really its max tilt angle).

Because you pushing you have control, auto = no control from user, I expect this is one reason, and on balance it’s probably not worth risking anything if there is absolutely no need to, bearing in mind that the drone is equipped to fly in the environment designed for it and will work well in this environment.

I think if any changes come they might be as a result of drones descending of their own volition, and I think this should be a more discerning issue to debate .

Not much to debate, there... from what I read it seems to be a serious problem, which DJI should acknowledge and solve quickly. I have not experienced that on my MM, hopefully they are not all affected.

Dirty Bird Posted at 3-20 16:01
Less mass is a positive in that it takes less thrust/power to stay airborne, but a negative for getting pushed around by the wind. I believe the Mini's max tilt is 30° in Sport mode, 20° in P-mode.

Yes, 20 in P-Mode and 30 in S-Mode. I was talking about the RTH max tilt, which seems to be 20, but I cannot confirm for sure. On the ACs you were able to hack into, was the RTH max tilt a separate parameter from P-Mode max tilt, or are the two linked?

For RTH, Mavic Mini's Max tilt and Max motor RPMs should be set to same as it is for Sport mode.
Whether on RTH, Mavic Mini's Max speed (GPS) should also be set to same as it is for Sport mode, is debatable.

Some would argue by going slower it saves battery power.  However, by going slower, the drone has to use more power to keep drone in air for longer flight time back.

It doesn't work that way. Any battery can supply a lower current for a longer time as opposed to high current for a shorter time. If you increase the current drain significantly, the battery terminal voltage can fall quite dramatically, and that can and will trigger a shutdown of the aircraft. It is worse with the Mini because it only has 7.6 volts to start with, but if the terminal voltage of the packs drops much below 3.6 volt, the onboard electronics, specifically the main processor, will reset, resulting in a loss of aircraft.

Mavic Mini having less mass would not be of issue for it coping with strong wind.  Main effect of Mavic Mini having less mass is it would respond quicker to chagnes in wind speed.  More mass would have dampening effect.

Nobody is saying Mavic Mini can cope with strong winds like Mavic Pro or Mavic 2.  But Mavic Mini on RTH could cope with stronger winds than it currently can, if DJI made some firmware changes.

One firmware change being Mavic Mini switching out of Sport mode to Normal mode on Auto initiated RTH.  Instead, having Mavic Mini switching from Normal mode to Sport mode on Auto initiated RTH.  Allowing Mavic Mini to use Max tilt and Max motor rpms it does when in Sport mode.

Drone batteries are designed for moderate to high output.

Nope, it applies more or less the same to most common types of battery, such as Nickel-Cadmium, NiMH, LiPO and Lion. Apart from that, the rise in internal reasistance of a cell, causing a sudden drop in terminal voltage is common to just about all batteries.

The MM can already fly in S-Mode, and I have not seen any reports of sudden shutdowns or resets, so we can assume it's a "safe" mode, which the MM power system can sustain.

A tilt angle of 20 degrees is probably more efficient than 30, but if you're in a situation where 20 doesn't make you move forward and 30 does, I'd take 30. No guarantee it will have enough battery left to go home, but at least it tried.

It's understood we're talking about a narrow window (winds between 8m/s and 12m/s), but it's such a simple tweak in the firmware, that I really don't see any downsides. And if it turns out that 30 is too much for whatever reason, make it 28, or 25. It's always better than 20.

Evan an Inspire 2 doesn't go 65 mph. What makes you think the Mini can? If one did manage to hit 65 mph, it was in the process of crashing or falling from the sky.

Inspire 2 goes 65mph. Inspire 1 has been recorded to hit 90mph+ w/ the wind by at least 2 users.

There was a video someone put up but now he deleted it. The telemetry was showing 65mph+.

AntDX316

Dirty Bird Posted at 3-21 01:35
The max speed of an Inspire 2 is 58 mph. When originally announced the max was listed as 67 mph, but it was reduced to 58 mph for production units to maintain camera stability. The Inspire 1 is only 50 mph. Either way, the Mini does not do 65 mph, or 50 mph, unless caught up in a gale or crashing. Could you please try to stay somewhere near the confines of reality?

This is why it's just easier to just stick to an M2 or a Spark.  All the issues of trying to make something work w/ workarounds and hacks is bad.  Also trying to explain what has been seen that has been deleted is also bad.

https://forum.dji.com/thread-182323-1-1.html

I've hard arguments when people didn't believe certain things that had people upset at me but once I showed them a video, they all talked amongst themselves.  I'm not going to say what it was but was something bad and serious at Liveleak.

I've also had arguments with people in a motorcycle sportbikes group but once I showed them videos to compare, no one bothered to respond after.  Mind you, there was a response from someone new nearly every 30 seconds.  It was about how the MotoGP engine style crossplane I4/V4 or w/e sounded like a well-refined lawnmower and the I4 sounds like F1.  I went to MotoAmerica event in real-life and the bikes that sounded like F1 were more amazing imo.

Why did I join DJI in late March 2019?  Because I wanted to film me like a 3D mirror.  I eventually grew into presentations which I have yet to complete.  If you cannot produce things people could see, people may never believe you.  The degree of confidence at which someone trusts something is directly related to how good the presentation has been engineered into their mind. I don't work like that or at least try to.  I see results, then look backwards.  It can be a great guide by the universe to not know certain things but we are coming to the point where it could be impossible to hide anything.

Hey ANT, check this out: https://mavicpilots.com/threads/ ... -assistant-2.77216/ As long as you are tech savy enough to follow, you can set your rth speed and w/e else on the mini. People have already dumped all the params that the mini has to offer, so if you want that 40mph mini or greater rth speed have at it.

I spent the better part of yesterday restoring all the function of the DJI Assistant 2 from 1.12 to the mini's version 2.10 and stumbled upon that thread where people cut the line in short and just wanted dev tools for the mini vs the full suite but w/e. I've yet to write any new settings to the mini but I'm able to read and send commands, when I feel a bit more comfortable I'll try adjusting my RTH speed to 10m/s and some other things and report back.

This tool exists and no firmware or hacking has taken place, in reality DJI left out the files for the ground station and developer tools in the newer assistant and just packing the old files with the new doesn't fully fix the problem. I'm in the process of updating old files with the new/correct syntax and other changes DJI has made so that Full functionality will be restored to DJI Assistant.

Dirty Bird Posted at 3-21 04:34
You have drifted off into things irrelevant to this conversation. The Mavic Mini performs RTH at 17.9 mph. It is not capable of, nor is it designed to, fly at 65 mph in any normal flight mode. While the Inspire 1 can fly at 50 mph, & the Inspire 2 at 58 mph, both RTH at only 22 mph, well below their maximum potential speed. The same applies for every DJI model. All can be lost if contact is lost while operating in winds beyond the design limit.

The simple solution is DON'T FLY THE MINI IN CONDITIONS EXCEEDING ITS DESIGN LIMITS! If you insist on doing so fly into the wind, or perpendicular to the wind, so the aircraft has a chance to get back should contact be lost. If you ignore these simple suggestions then the only person to blame should your Mini be lost is yourself.

I'm just saying, it can be done if the developers allow.  It's a software modification that is required, not a hardware.

If you have a tailwind taking it, they go faster than their maximum speed.  The maximum speed is when there is no wind or at least w/ the stuff I've seen.  The Mini might be different.  There are many ways on how come it sucks at RTH under certain conditions.  All we can say is, those with the Mini are on their own.  58, 40, 20, w/e.  I just think its hardware capable of making it at least when the tilt angle can be set greater to start.

We just need to realize something.  They don't allow a 50mph+ RTH because it can cause damage if the altitude is say 20 feet and it darts back w/o seeing what is in front w/ no OA.  It's capped at 20mph so it doesn't cause too much damage so the government doesn't get involved.  Like banning bump stocks on guns.

Hey ANT, check this out: https://mavicpilots.com/threads/ ... -assistant-2.77216/ As long as you are tech savy enough to follow, you can set your rth speed and w/e else on the mini. People have already dumped all the params that the mini has to offer, so if you want that 40mph mini or greater rth speed have at it.

The thread link doesn't work.  You can change the parameters w/ 1.1.2 (or w/e the version is (on my other PC) w/ the Mini after modding it in some way?

That's what I did to my other drones.  I do not have the Mini.

These are some crazy workarounds.  Just get a Mavic Air and jkson mod and variable mod and move on.

DJI released a tool for experienced pilots to modify the params of their drones, it's not for the avg consumer because you can damage your drone and it won't be covered by warranty. This isn't really a work around, more of DJI changed formats and it broke a lot of the old stuff and they never updated it. So by Jerry rigging the old software or updating it like I'm in the process of it's DJI's own tools to modify there drones.

I would be almost certain that tilt angles for Mavic mini where engineered by pretty good dji engineers and I’m certain they didn’t just throw mini together without any thought of how it would fly in environments they recommend.

What your looking for will not save any drone from being lost, we know this because from large to small drones , some have been lost to the wind, but by far the majority where lost by beginners and I would say that this is close to 100% for mini users.

No one complained but considering it is a very small and easy change of a number in the firmware and the potential to provide a bit more insurance to users. I think it is worthwhile.

But given DJI had a track record of not making failsafe RTH the max capable speed. They probably had a reason to design it this way and it might make the proposed change not worth it for them. No matter what DJI does later, I think users should fly smart and not operate with a bad link to the drone. They can always push the drone into max speed (46.8kph) to fight the wind as long as the connection is there.

For RTH, Mavic Mini's Max tilt and Max motor RPMs should be set to same as it is for Sport mode.
Whether on RTH, Mavic Mini's Max speed (GPS) should also be set to same as it is for Sport mode, is debatable.

For any vehicle (except for those in vacuum generally speaking), there is a max fuel efficiency speed. It is probably P mode max speed 28.8kph for mini. I am just guessing. Following my logic, S mode does get you home faster but at the cost of worse fuel efficiency. I suspect it is why DJI has made failsafe RTH speed not the max speed for drones including the mini for the efficiency reason. But from a "what people should do" point of view, I think DJI will not do anything because to lose your drone a gust while having no connection sounds highly like pilot error.

I do like DJI to increase the failsafe rth speed so the users who do the right thing but are unlucky enough to lose connection and get caught in an unpredictable gust can still be saved by this easy quality of life change from DJI. We do not have to have it if we choose our flights sensibly. It is just a very easy insurance for very unlikely scenario. Certainly not worse 100+ replies in a single post...

Less mass is a positive in that it takes less thrust/power to stay airborne, but a negative for getting pushed around by the wind. I believe the Mini's max tilt is 30° in Sport mode, 20° in P-mode.

Probably 25deg for p mode. I say it because when gimbal hits the +20 deg limit, max acceleration to full P mode speed forward (means reaching max down pitch) drags the gimbal down to -5 deg. The range from 20 to -5 is 25.

I think the fact you keep harping on about something that almost certainly won’t save any drones leads me to think this is more about trying to save some face rather than saving anyone’s drones.

They’re much better ways of helping others and yourself to keep your drone flying and out of harms way, I’d suggest taking on board some of that information.
