Wingsland S6 battery tests

Being that this quad has very short flight times, I used my first one to test out some different batteries.

I made up a lead to go from inside the quad to some outside connectors.

Using a Turnigy 2s 1600Mah normal 4.2 per cell pack I got about 7 mins.

Could just about fit this in the battery compartment , although was a very tight fit.

 

Next test was getting hold of some LiHV cells.

The way I done this was to get a 4s 1400 LiHV pack and split the cells.

One has to be REALLY CAREFULL doing this!!

So if you try this and it goes wrong you have been warned ! Dont do it unless you know what you are doing.

 

New cells slightly heavier above

Original cells above

 

New cells soldered into original case….

 

Flight times were on my first flight I got 6 mins 50 secs and second flight was 7 mins 7 secs before auto low voltage landing.

So one can get a tad more flight time with upgraded cells.

Not tried normal flight yet, and would expect this to be better.

 

Voltages at end were 3.67 per cell.

Charge put back in was 1270mah @ 1amp 1:24:29 secs

So using almost 90% of battery in those 7+ mins.

After second run of these cells I put charge put back in of 1105 mah @1 amp 1:12:22 secs

 

I am beginning to think the only way to get this up anywhere near 10 mins is probably finding better props and or better efficiency motors.

As fitting a bigger battery going to be problematical.

Unless something changes on cell density in the future and allows about the same size cells…

2nd Banggood Wingsland S6

Well, being that my first Wingsland S6 had issues with camera where it would only show a blank screen on app, I ordered another S6 from Banggood.

Although ironically after downgrading the camera firmware on my first S6 after putting it back together after the tear down I done , it now works about 8 times out of ten.

So maybe was a connection or the older firmware that has improved it.

So the one on the right is the new one and the camera works on that every time!

The battery with the new one also came with higher resistance on the cells that I would normally expect, but a tad lower than the first battery.

Anyways, with a hover test. Was about the same almost 6 mins with new battery and with first battery I also got about almost 6 mins.

So it definitely seems normal hover flight time on a battery will be between 5-6 mins and would expect a bit more when flying around normally.

Will test this when I get a chance.

Would still like to try this out with the proper R6 controller, but still cant find these for sale anywhere.

So yup, I was just unlucky with the first one Banggood sent me and the second one works fine.

Although a interesting thing was on the first one there was NO led light hardware inside the quad.

But on the second one I can clearly see this one has the led hardware inside.

Bit irrelevant as thats another feature now removed from the app. I dare say flight time was bad enough without trying to run a led light too ๐Ÿ˜‰

Next post will be some battery tests ๐Ÿ˜‰

Wingsland S6 Tear Down and thoughts

Seeing as my Wingsland S6 had a camera which did not work most of the time, I decided to strip it down to see if anything loose.

Maybe these photos will also help others and show whats inside.

There is a lot of technology in these, the quad is packed with hardware.

Also interestingly, the board that drives the motors is DJI hardware!

So that kind of tells me that it should be able to react quick enough to say change of wind etc.

And also coupled with the Barometer covered and enclosed well, it really should be able to hold its height much better than it does!

This is also a photo I posted on the Facebook Wingsland Owners group of the barometer pointed out and its in a plastic shell with holes in the top and a small piece of foam under it.

So this really should hold its height much better than it does.

But I do wonder if it actually holds it height much better higher up and I assume it was originally designed to use the sonar and downward facing position camera for indoors and also under about 10-15 feet outside.

But as the sonar and the position camera are disabled in either the firmware or app now, maybe that is also why its poor (especially in the wind) at low attitude hold.

Again I feel this really well built little quad been really let down by the lack of app and firmware development.

If they could have updated the firmware, I feel reviews would have been much more positive for Wingsland.

 

Anyway, a few more photos of the teardown for anyone curious.

For the above which is the Arm CPU and video processing chip etc, I added some thermal compound to maybe help.

Other assorted pics

I added a small bit ofย  foam over the barometer, even though it already looked done well enough. and surely made no difference at all to the altitude hold.

There is also another pcb under the battery which I forgot to get pics of.

Its the wifi pcb.

But I think its clear to see this was a lot of hardware inside, but sadly due to the lack of development in the firmware/app has caused most of the issues in my view.

Also with the low flight time of about 5-6 mins and no where near the claimed upto 10 mins.

However I did see someone post a photo of flight time they got on the Facebook Wingsland owners group that got about 9mins before it landed , which is very impressive and maybe with the right conditions one could also get near that on a good day.

But most reviews seem to say its around 5-6 mins normally.

So to recap, for the price these now are is it worth it?

Depends on what you want from it.

The stabilization of the video is poor and probably better not to use it and use one of the other app video settings and then run it through some pc/mac software to stabilize the video.

The camera itself on this is good and in a calm day one can get some nice shots and maybe especially if you after some good quality still shorts, but you need very calm conditions for this to be of use when taking just stills.

With no wind, it holds position and height really well

What really helps with this is the Wingsland R6 Controller, but sadly there does not seem to be anywhere with any left!

I wonder if any more are even being made as it seems out of stock at all the usual places and no eta of when coming back.

Coupled with the low price you can now buy these on places like Banggood, I do wonder if they are just selling off all stock of the Quad and controllers and once its all gone that its.

Worth checking back at bangood if you still decide to get one as they do deals now and then and drop the price even more ๐Ÿ™‚

Even though I got a unit that had a pretty much non working camera , I do like this enough for what I wanted it for that I do have another on the way from Banggood.

Fingers crossed this next one works okay and will use this original one for battery mods and testing out different props etc.

So for me personally I think its still a great looking quad , awesome packing and presentation and fine if you have specific needs where this will fit in.

For a quick fly up take some snaps and video on a dead calm day, this might be worth it to you.

But bear in mind it’s low flight time and there’s a good chance there will be no more updates in firmware or app software, unless anyone at Wingsland is still working on something.

I also paired this up with a bluetooth controller , which although not as good as the proper R6 controller, kind of does ok for now.

You cant seem to use a wifi repeater on this like other quads out there though.

Seems the app will only connect direct to the S6 and wont go through a repeater, but I guess with such a short flight time this is not too much of a issue not being able to increase the range.

If Wingsland are not updating this quad anymore,ย  I wish they would release the FTP / SSH passwords, so some of us could connect to it and maybe adjust some of the internal settings to address some of the issues.

I have checked out the flight firmware and its encrypted so no way in via that route either ๐Ÿ˜‰

Wingsland S6 Dobby props

Well for my next test with props, I tried some Dobby ones.

Had to fix a small piece to dobby prop holes as they were too big for the S6 posts.

I used very small tube from a pen! which fitted just about right and still left them loose enough to move.

But trying to fly with these props did not work that well.

The dobby props must be a smaller pitch angle than the S6 props and it only just about got off the ground.

I think the Dobby uses the same KV rated 4300KV that the Wingsland uses.

The dobby weighs a lot less than the Wingsland and so I assume the props dont need such a high pitch angle as the original S6 ones.

So need to find some other props to try.

Wingsland S6 Camera issues

Well done a few flights with my S6 now.

First offย  even though this is the S6 V2 Advanced edition, DO NOT TRY AND FLY THESE INSIDE!

First 4/5 flights I tried indoors , the quad took off and flew straight up into the ceiling!

Chipped all the props and put scratches on the top of the quad.

Even on this version , the sonar and position flow is not working (presumed disabled in the firmware)

Tried it outside and it shots up around 10 feet from take off and then drops down a bit and settles. (That explains why it hit the ceiling in my house)

On my model the camera does not work most of the time, I just get a blank screen, although it will still take off and fly but wont record anything , as it does not sense the camera.

I tried loads of different SD Cards and formatted them from within the Wingsland app and still it only works about 1 time out of 10.

So I defiantly have a faulty unit.

Just not worth the hassle to send it back to China and so I will end up just taking it apart and seeing it it has a iffy connection etc.

Flight time was really poor.

Seems to be between 5 to 6 mins max before it autolands.

It’s using 1100 mah from battery for those flights.

Checked by using a balance charger and I made up balance charge lead so I could see what the voltage and mah put back in was.

End voltage after a flight seems to be around 3.74 volts per cell , so I am guessing this lands at 3.6 volts a cell.

I need to connect something up to see just what is the critical landing voltage, but seems they are being too cautious on low battery voltage unless its a really low C lipo and its landing at around 3.3 per cell under load?

I also tried some bigger props , DJI Spark props.

Did not fly too well due to being too big, but they just about fitted and was curious what they would do to the flight time.

Was a tad longer as it turned out, but have some better props on the way to test , as I think with better props and modding the battery maybe I can push this to a more reasonable 12 mins flight time at least.

Photo of S6 with DJI Spark props:-)

Anyway, had a wind free slot in weather yesterday and it flew really well and camera actually worked for a change!

It took off to about 10+ feet and I left it with no inputs until auto landing.

It hardly moved and really held position well.

So in no wind , this flys well apart from the low flight time.

I think Wingsland should have made a extended battery for this.

I guess because battery fits inside quad the changes of ever seeing that , even from third party are very slim.

If they could have worked on the firmware to make it more reliable and got the sonar and position flow working and given it a flight time of about 12 mins , they would have had a far more successful Quad!

Most of the reviews on these are terrible and I feel a lot of the issues could have been fixed by more firmware upgrades.

But although the app was updated recently, I doubt we will see any firmware upgrades.

It looks really cool and the packing and presentation is excellent.

Real shame and it seems they are no longer sold now with stores just selling off what stock they have.
