DJI released the tuned propulsion system e300 and e600

[DJI Innovations]

The E series tuned propulsion system is the first power solution of its kind for the multirotor industry. It brings greater aerodynamic efficiency and higher thrust-weight ratio, while increasing reliability, stability and agility.

"Tuned propulsion system". So, propeller, motor and ESC.
I will get in my "multi-axle personnel transportation device", proceed to the "specialist rc items vendor" and exchange some "negotiable currency" for your "tuned propulsion system".

How much do I not want to be locked in to a specific prop, how much do I not want a motor with an integrated prop adapter, 20A ESC for 35xx sized motor, so its no thanks all around from me.

For what it is worth, the efficiency of a system design often is compromised most by the propeller which cannot be custom made for each AUW etc. Getting a motor - esc combo to match is much easier.

HA, DJI Mentioned "Reliability".. Sorry, had to say it.

Here is what I see, typical Chinese.... The lower KV motor has a specific clockwise or counter clockwise thread for the prop to tighten onto. One hit of something and the prop is ruined, so you will have to go back to DJI for new props, if you can find them. Propriety equipment is what DJI are trying to make, you will never get any other prop on the motors which I personally do not like. I will stick with my Graupners thank you, they work great for me and a lot of other people on here.

Having spent a lot of time creating optimum settings for my motors I know how much difference it can make. You can start getting into motor rewinding and learning how to use ESC32 Then you need an accurate test rig.....or you can buy something like this that is ready to use, or you can carry on taking pot luck and hope it runs smooth enough to be ultra stable and can stay in the air for a reasonably long time. Components like ESC's are made to accept a wide range of operating conditions.
Try running you car with the ignition over or under advanced.

DJI catches so much grief because they sell product like nobody else. This is a great example. For someone really into matching just the right motor to a frame for a given payload, picking their ESCs, matching the props, etc., this won't be the ideal solution unless the weight of the rig just happens to hit the sweet spot of one of these systems. But for a newcomer, this simplifies things and that is clearly where this market is headed. I'm new to this market myself, but I like the build process and technical stuff as much as the flying. Most people, I'm guessing, just want to fly with minimal hassle. DJI is headed toward end-to-end plug and play. They already have it with the Phantom. Just look how popular that has been. On top of that, the e600 looks like a really attractive option for a nice medium sized hex rig (say, for an rx100 or NEX).

PMSL.... legend.

So in essence, you're saying you will have to know what the craft and weight this system would have to match. Not quite tuned for everyones need is it? This and many other reasons is why they catch so much grief..... Rather then fix the problems they have, the just churn out more junk like this.

Well sure -- obviously you couldn't just slap an ESC/motor/prop setup on anything and expect it to fly well. The "tuned" description refers to the combination of ESC/motor/prop, and until we see how it performs there is no reason to trash it. There is this persistent meme of bashing DJI and it's just boring to listen to over and over again. When someone actually owns something that fails it is interesting. Knee-jerk complaining is content-free.

I generally think this is a good idea, (Note: Idea) how the implementation is we will have to see. From the spec on the website they are suitable for small to medium lifters

E300 300g/axis recommended load, 600g/axis max, so 1.2kg on a quad and 1.8kg on a hexa
E600 600g/axis recommended load, 1600g/axis max, so 2.4kg on a quad and 3.6kg on a hexa

I am surprised by the low amp esc that are offered.

It would be interesting to see how real thrust & current draw compares to other systems, I hope that we could start to see other manufactures offering a similar arrangement of products. For sure some shops could put kits together but this does not mean that they are "Tuned". e-calc is good to see what your setup should provide but a lot of motors are not supported so it is still hit and miss.

What would be great is to start to see a standardised test to measure these types of configurations, with this it should also help to drive the industry to create better performance systems.

Anybody care to state what they think should be a standardised test?

An obvious start would be something like net thrust per watt at, say, 60% throttle (net thrust being net of combined weight of prop/motor/esc.). A "tuned" combination should maximize thrust for a given combined weight. Beyond that, there are less tangible things like minimized vibration, just for example.

Does anyone notice how the new E600 motor bears a uncanny resemblance to the new Tiger Motors U series. It is identical and that is good because the new U series motors are supposed to be awesome.

Yeah, I noticed that. If they're from the same factory but re-badged, that's good news.

They will make motors to any spec. that you want in any color with your name on it. I doubt that DJI make em themselves or the ESC's. But they will have done exhaustive testing to create that spec.

Give it a couple of weeks and they will all be selling (so called) matched components.

The name of the game is volume. The mass majority of people building stuff at home do not have a clue what they are doing so they buy just about anything that looks like it is expensively suitable. The people who actually have the skill and equipment to analyze what they are putting together have been doing proper selective assy. for ages and testing it on rigs. before it even gets fitted to a frame. The idea that the prop. alone will dial in to make an efficient system is totally based on Guesswork. Some of the comments above prove that the market is driven by trends based on forum delusions ignoring the fact that most of them eventually drop out of the sky.

As they say in the real world of design engineering "When facts are few Bull**** abounds"

It is not for nothing that certain craft like the Phantom Vision and some bespoke designs have shown endurance that others cant come close to.

I swopped out a set of standard Phantom motors to test a set of Kopterworx upgrades and guess what it had more power, which it does not need, and the endurance went down by 10 %. DJI are not exactly novices at this game. There is good and bad in everything in life and due to the price and volume I would have to say that you will find the odd motor that is a little out of balance but I have seen this on some so called premium spec. motors.
