Likewise with 3 TX's and their modules and over a dozen receivers, all done OTA, the only issues I've seen on the FrSky facebook group and RC groups have been down to user error, most if not all resolved with doing a wired update.

The X20S doesn't have the twin protocol in it so will never bind to a twin receiver, it has TD Access and ACCST V2, if you want to use a twin receiver you are going to have to put a Twin module in the back.

Either use the NiCad setting to start of the charge then after a few minutes revert to LiPo charging OR connect two of the same LiPo's together with the good LiPo at storage charge only) through the balance leads (using a parallel charge board to do this), after a couple of minutes reconnect to the charger and charge normally. This works best for me with small batteries, large batteries might not be fully recoverable so test thoroughly.

Well I've always said if you can't charge all the batteries you want for a days flying all in one go you'll soon get fed up with electric flight which means that I need to charge twelve large packs plus small four receiver packs. The ones that I have use two of the small fans that most chargers use so pretty much no difference between these and other similar chargers, besides which it's academic because I would never hear them over the two servo power supply's!

I've got five of the HOTA F6 Quad Channel Chargers, a couple of which are over three years old, best chargers I've ever had with so many useful features, can't speak for the others.

I've made literally dozens of these over the years. Very high output, up to 87 amps, I use two of these to power two quad chargers each so in effect eight chargers for each power supply with each charger charging a 5 cell 5,000 mah pack so eight batteries per power supply being charged. If you go down the route of converting a servo supply make sure you know how to turn the 12 supply on, for instance with these ones you short together the three pins in the photo. However beware, high power they are and very compact too, but the one thing they definitely aren't is quiet! You also need to use at least 12 awg wire from the supply to the charger and that assumes you have two + and two - connections of you'll get too much heat in the wires. The good news however is that these are in effect electrical waste with virtually no demand for them, the last lot I bought were advertised on e bay at £30.00 each plus postage at cost and they had 12 of them, I offered to take all 12 for £100 and they pay the postage, and they accepted the offer.

You can do multiple things, for example voltage against current in excel Or all data in something like the free programme Flow csv viewer

Valid data is definitely there, this is your csv file opened in excel, so exactly what are you trying to achieve?

I'm wondering what the difference is between the two files that are both .csv files but that appear to be from the one flight, one is called ._00001187 the other just 00001187, if you care to attach the files here we might be able to help a bit better (no guarantee of that though)😁

Go to File, then import, there are a couple of csv options there, try both?

A .osd file is an open document spreadsheet, click the arrow next to it and if available change it to all files, then the csv file should appear so click that and see if that works.

In your last photo showing dataExplorer open go to the file option on the top left and open the file you want to look at from there.

If you're still having trouble then if you post the .FLD file here I'll have a look at the file structure and see if there is an alternative way to do this, it's got to be a pretty simple prcocess.

I do, a few hundred cycles, on the basis that electronic items, if they are going to fail, normally do so when quite new, if they pass then they should have a long life, known as the bathtub curve.

I'm not a Futaba user but I can tell you that you won't be able to open those files in any programme because they are a Futaba specific file type so you need to use Futaba software to use them. Specifically you need to use the Futaba telemetry log converter software and instal it then you can convert the files to a .csv file and view in a spreadsheet such as excel. However it appears that this is Windows only and IOS isn't supported so you might not be able to use it, however the Futaba instructions are attached. Hope that helps to explain it.
