Fantastic result. Well done that man!

That's looking great Martin. Good luck with the maiden.

Often, cooling works better with LRF support.

Excellent challenge Martin, I love it.

I'd link to the many threads on this particular model from when it was a mass build subject its self, but that would be distracting and take up your time.

I'd also link to my thread on building a N Hawes Whizzza in hotel bedrooms while working away. But I won't. If I can do That, I'm sure you can do this.



Thread: FrSky Major Update for most TX and RX
16/01/2020 19:47:18

Thanks Andy48. I hadn't spotted that change in 2.3.

On upgrading a Rx with a Horus, I don't believe an X12 has an S.Port socket?

It can be done from the module pins but then you need to take into account that the supply voltage on the module pins might be higher than the Rx will handle. As usual there's a new number of ways of doing these things.

My easiest option is to use the module pins in my old Taranis to do Rx upgrades.

Thanks for the heads up Kev.

First of all, if I don't do this then my gear isn't going to stop working.

Second, it's very nice of them to tell us it needs doing, but have they instructed us how? Are files available for non FrOS users or do we have to go through the process of converting back to FrOS and then back to our favourite system again?

The cynic in me wonders whether this is an update just to stop cloned receivers working?

KC that's good news. Jon is right, a PATA one really would be too old to be worthwhile.

With a laptop, I'd think that there will be a small cover you can remove to get at the disk. So no need to take it all apart. Whether you go down the new install or the clone route, you'll always have the option to pop the old disk back in to restore it to exactly how it is now.

KC just before you order, are you able to inspect the original drive?

If old enough it could be a PATA drive. That's a parallel connection rather than SATA which is serial.

PATA will have a wide connector with many wires that takes up most of the width of the drive. SATA will be a much narrower cable with only a few wires.

Corné, I've updated this thread with up to date details of my unit. The rest of the thread might be of interest.

Thread: Power Safe for any receiver
10/01/2020 22:05:12

PS Here's a shot of the one installed in the Chippy.

One unexpected feature is that the Rx can be popped out easily without disturbing any of the wiring at all.

Wow - I didn't realise it had been close to a year since I updated this thread. I've been developing this unit, on and off for a while haven't I?

So - bringing things right up to date:-

To recap - this unit takes two separate Rx supplies (2 batteries, a UBEC and a battery or two UBECs) via decent connectors and combines them via two schottky diodes thus giving supply redundancy.
This supply is then applied using a wide PCB track, doubled up on either side of the PCB, directly to all the servo ports (not via the Rx tracks).
The supply also feeds the receiver (via two routes for redundancy) and the servo outputs are routed to the servo ports.
I've now included FrSky S.Port telemetry to the PCB but this can easily be omitted.

The big limitiation now are the diodes. Because of the volts drop across them and the servo current through them, these do dissipate some power. So they can get warm or even overheat if servo currents are too high.

I now fly this unit in a Segull Chipmunk. In this model an FrSky Neuron ESC provides a UBEC supply and a 2S LiFe provides a backup. I call this the backup supply becasue I've set the UBEC supply to a slightly higher voltage than the battery. Therefore the UBEC supplies all the power. The idea is that if this fails, the battery will take over. The radio is set up to warn me with voice alarms if either supply is lower than it should be.

It's quite amusing to disconnect the LiPo from the ESC, which obviously removes the UBEC supply, and hear "Warning - Systems are on backup power ".

A 3d Printed box makes for a neat installation and two LEDs show the status of each supply.

Afternoon (in the UK) Corné

I've made good progress with my dual battery solution.

I'm at work at present but will try to put up some pictures and explanation this evening.

It works very well as long as you understand it's limitations and don't expect it to replace all the features of a proper power box.

Bob you can change the names so you could have PortV and StbdV etc. That might help?

Hi Ian and welcome to the forum.

That all sounds really interesting. You'll find some like minded friends here, to be sure.

Thread: FrSky Neuron ESC
22/12/2019 19:02:47

Mike this is now the section I have in the script.

local sensorIdTx = 0x17 -- sensorid 18
local sensor = {sensorType = {selected = 13, list = {'Vario', 'FAS-40S', 'FLVSS', 'RPM', 'Fuel', 'Accel', 'GPS', 'Air speed', 'R Bus', 'Gas suit', 'X8R2ANA', 'Neuron', '-'}, dataId = { 0x100, 0x200, 0x300, 0x500, 0x600, 0x700, 0x800, 0xA00, 0xB00, 0xD00, 0xF103, 0xE50 }, elements = 12 },
sensorId = {selected = 29, elements = 28}}
local selection = {selected = 1, state = false, list = {'sensorType', 'sensorId'}, elements = 2}

selected = 13 is indeed now making the default selection "-".

The change of dataID for the Neuron has made no difference. This is still reading Neuron as 16 where the FrSky SBEC script reads it as 17. I don't think it's a big issue. Unfortunately I don't have another way to read it.

No reason at all Tim, that's what it's there for - to set to what you want it to be.

I have a model that has two supplies. each via a shottky diode. One supply is this UBEC, the other is a LiFe pack.

I set the UBEC to a voltage slightly higher than the voltage of the LiFe pack. This makes the UBEC my "main" or "preferred" supply and the battery is then the backup supply.

Thanks Mike.

I'll have to find some more time to try that, but I will.


22/12/2019 15:23:41

Oddly, FrSky SBEC.lua reports an ID that's one number lower than that reported by chgID.lua

22/12/2019 14:40:03

Of course, having done all the above I tried FrSky SBEC.lua from the latest SD card download.

That now also allows the setting of Physical ID on Neurons.
