|Go to the Links tab on the OpenTx website and you will find a link to my docs near the bottom.|
|Im on holiday right now. D8 mode is available so long as you uncheck the EU box in Companion before installing. As far a going from FrOS yes you do need a backup copy in case they ever update the transmitting module firmware but it does not have to be the most recent version. Not easy on my mobile to give a link to my docs.|

|Thread: Safety plug|
...... but the salient point is that you CAN extend battery leads up to at least 8" or 20cm with no adverse consequences, which should be enough for most of us. So often on here you are given the impression that battery leads must not be extended at all.
I think this is a very valid point. Having safety plugs on all my models means that I now have a fixed routine so that I only insert the safety plug when actually on the flying field in a position to take off, and always remove it as soon before the plane is moved from the flying field. Thus it has become almost automatic, and the only time I really have to think about this is when I am testing a model in the workshop. Indeed the safety plug clips on to the transmitter strap hook as a double check.
Sorry but your argument makes little sense.
I'll stick with the old wives tale theory. It may have been accurate years ago, but if it is still true then why is there nothing in the instructions of any of my ESCs about the issue? Its is also interesting that all references to the problem seem to go back to the guy Geoff included the reference to 10 years ago.
Also can you explain why I've never had an ESC failure in 10 years? Most of my ESCs are Hobbywing ESCs of one sort or another and all have survived long leads over an extended period of time.
One ESC manufacturer, I seem to remember, did comment on long battery leads - Castle Creations. However if you follow some of the links from Geoff's reference you will find the following comment by them:
12" between where the wires solder on the ESC, and where they solder on the battery tabs on the pack. Anything over that and you want to add capacitors. Rule of thumb is for every ~4" over that you should add one extra cap that's the same voltage and capacitance rating that is on the controller.
Now we have a definitive measurement, which makes a whole world of difference. Clearly you can have up to 12 inches from the battery to the ESC, not as has been commented ANY extension! (Indeed the poster in Geoff's reference gets this wrong.) It is perhaps interesting to note that there is nothing in the current Castle Creations ESC instructions about long battery leads.

The article is now 10 years old, and probably based on earlier information and ESCs almost certainly will have changed since then. Also 10 years ago battery technology was mostly NiCad.
If voltage spikes higher than the battery voltage can kill the ESC over time, is this the actual battery voltage, or as I am inclined to think, the maximum battery voltage of the ESC? Surely then these voltage spikes will also destroy any extra capacitors you put in circuit, which being electrolytic will have a low voltage.
Finally, the lithium battery itself acts as a capacitor surely?
Is this another one of those issues which through time has become an old wives tale?

All I can say is it must be a very, very long run, because I've never had a problem with ESCs failing and some have been used regularly for the last 10 years with extended battery leads!
Er no. Its running a 5S 5000 battery, and a 1200w motor just to get the noseweight right, though due to the prop size you are correct and it is running around 600-700w. It will fly for over 30 minutes on this setup! Almost all my models have lengthened battery leads, in more recent times these have been needed for the in-line current sensor to be fitted. So far I have never had an ESC fail.
I'll stick a claim form in the post.
I have some very long battery leads in my Puppeteer, it hasn't done any harm so far despite all the doom mongers. The safety plug is actually the steering yoke in the cockpit. Not a very good photo I'm afraid, but you can get the idea.
|Thread: FrSky X10 - Taranis replacement?|
Tis a small world. I did not take the ICL job (they were on rocky ground then). Instead I went to work with Farnell Instruments (the components people today, then they also had a manufacturing division) as a development/production engineer building power supplies and electronic instrumentation. I did build some special power supplies for ICL though. I stayed there a few years before going into something more rewarding, and eventually back into computers.
Nah! No excuse. I was offered a job commissioning mainframes with ICL, and my first and only IT course (as a participant) was on mainframes with punch cards.
Bob and I both used different themes. Anyway the Companion screen is customisable so you can move menus about.
Bob, beat you to it! I suspect he has tried to find it without loading a model file first. Then you don't see the option to edit radio settings.
Geoff. If you find the USB difficult, simply take the SD card out of the Horus, and plug it directly into your computer, then you can access everything there through OpenTX in the same way you could using the USB lead.
Load the Companion and your models then simply follow the instructions/screenshots on section 4 page 2 of the documentation:
Section 4 of my documentation.
Whatever settings were on FrOS will have no effect on OpenTX.
I( suspect you do not have the volume turned up in settings:
Check both speaker volume and Wav volume.
Also you can use S2 pot as a volume control in Global Functions instead of MAX.
All these sort of things are covered in the OpenTX documentation referred to above. It covers flashing all the tx, and flashing receivers from the tx.
Yes X10 with internal, and X12 with internal. On the X12S you can have both internal and external on together, on the X10 you can have either the two internal or single external but not both on together. (OpenTX indicates otherwise at the moment, this is incorrect.)
Can't make your link work, but the instructions for installing OpenTX are in my documentation. It is essentially the same as the one I think you are linking to. It depends whether you like videos or prefer written instructions.

Chair legs, table legs, workbench legs. Yes, we've plenty!
|Thread: FrSky X10 - Taranis replacement?|
BTW, on a range check the X10 seems somewhat better than the X12 with the internal aerial. Checking the actual flight logs (on the same plane) it would appear considerably better. Anyone want to buy a used 12S?
