Mavic Air water damage

Got hold of a Mavic Air that had suffered a crash into a lake. Lucky enough this was fresh water and not a crash into sea water!!

Goes without saying the esc board was toast and so needed a new one.

Next job was to throughly clean all the ribbon connectors which always corrode when they enter the water. (But not as bad as what salt damage does)

But still took a while to clean up all the connectors with switch cleaner and very fine sand paper.

But the camera and obstacle sensors and gps were working all fine.

One of the antenna connectors on the main board was damaged and the outer ground connector sleeve has ripped off the board and still needs to be replaced.

On getting it all back together it powers up.. But……

I have to power it on and then power it off and do this at least 2 or 3 times until the remote connects. It must be sensing something wrong as it throws up solid red led. I assume it might? ether be sensing the signal strength to the antenna leg is not 100% what it expects due to damaged connector and split in the wire which I had to repair.

Or the main board has damage that was caused by water damage thats messing with the wifi, although on a test I done it seems fine the strength of signal once it connects.

This is where access to the logs would be handy, but alas this is not like the older models that one could jailbreak and read the internal logs. One can read the logs off the android phone, but that are not much help with the error.

So all in all this was more sucessful that most water damage quads I tried to repair, mainly due to it being fresh water damage and not salt water and also the esc board is separate and not too expensive to replace.

The main board for this way beyond economical though.

On to a test flight next…….

Wingsland s6 zerotech 1104 motors

As we all stuck inside , I thought I would try a idea I had before and that is to mount zerotech dobby motors on the wingsland s6.

Result ??? = Total fail!

When I hit take off it climbed about 2 inches and would not go any higher, the Dobby 1104 4300kv motors no where near powerful enough to lift the weight of a s6.

Still thats another test crossed off the list.

Wingsland S6 3D printed Battery mod!

I recently was contacted by a guy called Chris and he told me of someone who had designed a 3d printed battery case and holder for a wingsland s6 battery.

I am going to link this at top of my website as I think this is a major help to anyone with a S6 and disapointed with the normal 5/6 mins flight time and wants longer and also cheaper batteries as S6 batteries are way over priced for dumb cells.

Also with this mod, you dont need to rip open your S6, but you will need a donor s6 battery for the mod as you will need the battery pcb and solder a connector as shown in photos below.

Heres 2 pics of the Battery mod and the holder for the battery that can fit underneath and hence one can use diferent and bigger batts.

These photos are not mine, they are Stefano’s (The designer) photos and his property and copyright.

If anyone else intrested in sending Stefano a donation for his 3d stl files so you can print out the above mods , contact me via the “contact us” tab on top of my website and I will pass on Stefano’s details.

Once again a very big Thanks to Cris for contacting me and letting me know about this great mod and also to Stefano for 3d designing it.

Flyaway Wingsland S6

Just got hold of another s6 that someone was getting shot of and think I might be able to see why!

My first test flight of this tried to head off to the moon!

Just very lucky I had tethered with string for a first flight test.

After only 1/2 mins it just shot up to the heavens and the R6 remote would not control it, and lucky I grabbed the end of the string and stopped it and it crashed into my roof and battery flew out and busted the props.

Thats my first ever (almost) flyaway I have had with any quadcopter.

For sure without being tethered god knows how high it would have gone.

Lucky enough I had phone screen recording on and went back through the phone video and could see exactly where it all went wrong!

Split second before it fly up on its own all normal and coming to end of battery.

And then a second later notice what the reading of height and vertical speed has jumped too!

So I assume that craft thought I better throttle up and off it went.

Now why did readings go so wonky????

This dont really use sonar when in outdoor mode and so I am thinking maybe the barometer??

Edit: Thinking about it as the height and v/s speed went mad, me thinking it is prob like other drones and bases that info on gps too. So could be some iffy gps data confused it.

But to check all these things a full strip down now required and also something else I noticed is the fan is not spinning , although dont think that had any effect on this issue as its still cold out this time of the year.

Crash investigation to contuine and will post what I find, as it may help others why come across this issue.

Happy flying 🙂
