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!
