Wingsland M5 Test

First test flight of the Wingsland S6 after the repair (which I will go into in another post)

As you can see in video below, it has a lot of trouble holding height.

In fact I had to constantly raise the throttle up to get it back up and then after a while it

would start to drop again, hitting the floor once or twice.

On reviewing video from phone app recording I can see it was displaying correct height, so the baro was working fine, just software was not keeping its height.

The bottom sensors on this work much the same as the Wingsland S6 and that is they are not used when flying outdoors with gps lock, so kind of pointless having these sensors fitted as they are only used indoors and Wingsland advises against flying this and S6 indoors. Outside its flying purely with gps lock and trying to hold height with the barometer.

Winds were about 5-7mph and as always testing in back yard, a lot of turbulence.

Intresting to see if it holds height better higher up and away from all this turbulence.

Run time was about 10 mins 30 seconds, so pretty off the 17 mins they claim. (Although the cold weather certainly knocking it down a bit)

Video quality is only 720p on this and video is cut up into 5mins sections on sd card.

Once weather gets better , will head off and see how it performs at the beach.

One big pain with this is the motors DO NOT shut off if it hits anything like most quads.

This is really the second flight I made as the first one it landed and flipped over and carried on spnning its props and rocking about upside down and 2 of the props broke on concrete floor, and so had to wait for some props to come from china for this.

Wingsland X1

 

Just testing out the Wingsland X1.
Was only getting around 1/2 mins flight, but after squeezing back the weak brass connectors in battery so made better contact, on this test I got almost the 8mins it advertizes!
First Wingsland product I tested that has got near its supposed flight time.
Fun little thing and was designed just for that.
The camera is only 640 x 368 and only records direct to phone.
Being brushed motors , I darn say will burn out rather quick.
But flys well , as long as you do not fly in anything but dead calm wind.

The position flow camera not very good though struggles to get a lock, long grass not helping.

Wingsland S6 Indoor Mode vs Outdoor Mode

Thanks to a fellow friend and S6 owner, who originally let me on to this , and have mentioned some of this in a previous post.

On the old firmware and app versions , there used to be 2 modes. Indoor and Outdoor modes that you could select.

On the latest versions this option has been removed and you basically just have outdoor mode on all versions of the S6.

Indoor Mode

However you can still force the S6 into indoor mode.

This is done by starting the S6 indoors and making sure it is covered or deep in house, so it does not get any gps satellites.

You will know this as it gives a warning about no gps when you take off.

At take off in this mode , it does not climb as high as it does in outdoor mode.

Also the controlling of the S6 are almost at a crawl and hardly any movements are there in this slow mode.

One has to be careful as because of this , if its going hit wall or ceiling you wont be able to quickly adjust, so be careful if you do try this inside.

But in this indoor mode the S6 uses its bottom sonic sensors and position flow camera.

Also in indoor mode the height is limited to around 12 feet max.

This video is showing the S6 in indoor flight mode.

Outdoor Mode

In normal outdoor mode with gps lock, the bottom sensors are NOT used.

The S6 flys using gps and barometer only.

 

Conclusion

Probably very little reason for most to ever want to use indoor mode, it does wander a bit and the height lock is not very good using its sonar compared to other quadcopters. (This is probably why Wingsland pulled the indoor mode)

This testing was done, just to see if bottom sensors are still actually enabled at all and they are , but they are really deprecated features now and removed from app.

This also explains why when I have done tests with the bottom sonar board and position camera removed it flys exactly normal outdoors.

So in theory you could remove them, but as with including plastic bottom cover it all weighs just 8 grams. Not really going help much with flight time.

Also note, because of when S6 picks up GPS it goes into outdoor mode, its HIGHLY advisable NOT to fly this indoors.

The S6 picks up sats really easy indoors unless you are buried deep and then trying to fly indoors , but in actual outdoor mode the quad will try and gps lock its position and as I found out early on, end up in the wall 😉 Also the take off height is a lot higher and yet again as I found out, will hit the ceiling unless you have a really high ceiling!

I think some where I read even wingsland does not advise flying the s6 indoors and you can see why.

Zerotech Dobby Hover test

Indoor Dobby hover test.
Curious how well this hovers indoors compared to the Wingsland S6 in indoor mode.
No comparison really , the Dobby wipes the floor holding altitude and position.
A real shame Wingsland could not get the S6 to hover and hold height as well as the Dobby does.

And also a real shame, Zerotech never brought out a dedicated controller for it.
The drop and crash at end of video was caused by some temp plugs I hooked up to use a 2s lipo I had lying around and connections came loose.. opps
This Dobby is now grounded due to the ms5611 barometer totally failing, as it kept reading crazy altitude and would not arm and gave off a abnormal barometer error. This now happens all the time and so needs to be replaced.
Have one on order to see if it is the barometer itself or some other fault on Dobby.

Wingsland S6 test with Gemfan 3025

Test last summer with Gemfan 3025 props.

Issue here is the holes dont line up as they made for 5mm spacing and on wingsland its around 9mm. So for Test just pressed down on center shaft with a bit of locktight.

Bit of bouncing in this one , gets a bit confused and does this at times with stock props too.

Wingsland S6 test in gusty wind

Just going through some videos from last year and this was one from Sept 2018.

The S6 started having problems trying to hold in gusty wind.

Problems start around 2/3 mins into flight and the wind picks up.

To be fair this test was done in a back yard and therefore lots of turblence.

But it is a test I do on all my quads to get a idea of how they handle the conditions.

The S6 seems to be slow to react and them slow to brake from over corrections. I think a lot of this could be addressed by fine tuning the pid’s . But sadly be do not have any software from wingsland to adjust this.

To be also fair this test was done using stock props, but using a 2s Turnigy 1600mah standard lipo so was heavier and therefore would add to trying to recover in the wind.

Faulty Wingsland M5

Just got hold of a faulty Wingsland M5.

On power on all it does is this:-

In App shows battery 0% and also no reading from sensors at bottom.

So first thought was maybe something loose inside or some power issue?

So teardown time 😉

Once I got this apart did notice something on the connector from esc board to main board , on the bottom right 3 of the wires were stripped bare and possibly touching when together? I noticed this before I took plug out, so I know it was not my own doing.

Above is the M5 esc board

Above the sonic sensors and optical flow camera.

Above front of M5 with gps and barometer

Side view of M5 showing the flight controller board

Another side photo showing the IMU and camera

Rear view showing leds

Anyway, back to fault..

I have now checked all the mosfets in case they were to blame and all power rails seem to be fine.

Intresting I feel is the fact the app shows battery at 0% , but also the sensors have no value.

Camera works and records fine, so is there a problem with comms bewteen wifi and flight control data?

The R6 is connected and has solid blue light, but in app says disconnected, a clue there me thinks.

Anyway, off to fix those bare wires first as that could be related.

Faulty Zerotech Dobby

Just got hold of a broken Zerotech Dobby.

Quick test, it powers on okay but has a Barometer error which wont clear.

The error in the app is:-

Could be a firmware issue or just faulty Barometer, have to get it apart to have a look first.

So  Bit of a teardown needed 😉

Guess the baro must be under main board maybe near when the rear optical flow and sonar are , so main board needs to be unsoldered to raise the board.

Will update post, once I got it fully apart…….

Have to take the black sticky ccover off bottom to release the main board

But got to the bottom of the board then and its using a MS561101BA03

for the barometer, soldered to the front bottom of main board under a bit of foam.

Hard to see , but number on it is a MEAS 561101BA03

Might try reflowing it first , before replacing it.

Update 31/01/2019

After reflowing the barometer chip and putting the whole thing back together no change.

So either it is faulty or a resistor etc around it faulty or software issue.

But… It will work if…… If I start it up and leave it for 3-5 mins and the restart the drone and the altitude reads stable and I dont get the error.

So when cold it brings up the barometer abnormal error, and altitude jumping around all over the place. When warm it is settled.

Maybe in the summer it wont be such a issue, but if I decide to go further with this quad, I will probably replace the baro with a new one first.

Wingsland S6 Video indoor flight Tattu cells and stock props

Flight test below was done by forcing the Wingsland S6 into “indoor mode”

Please see other video on how to do this and cautions using it.

So again this was done using Tattu 1550mah LiHV 100C cells.

Was testing in same coniditions as last indoor test and this flight time was done on stock Wingsland S6 props was about 1 min shorter flight time.

Notice how on take off height jump not as high as when using Fairy props.

Also note the warning on using these props!
