Horus & FRSky OS Difficulties

[Andy J]

Finding the set of a petrol engine model with 8 servos a bit of a pain as seldom play with all the functions of the Horus and its software.

 

Conventional channels for el, rudder and aileron are fine but need to add a kill switch to channel 7 with and a second enabling switch.

 

The logic being that a momentary switch can kill engine and a second fixed position switch can enable of disable the engine.

 

Input channels are defined as Aux1 being a momentary switch SWH and Aux2 as SWF. Output channels are defined as Chan 7 Aux1 and Chan 10 Aux2

 

Unclear to me if this is a logic mix of channels 7 & 10 or do I combine channels 7 and 10 in some way using the Ex mixer function.

Hi Andy

 

I have an ignition kill switch on a momentary switch using an 'engine kill' gizmo, and a throttle enable/disable on a two position switch ? Is that what you need ?

[Frank Skilbeck]

Not familiar with the Horus, but wouldn't a logic switch be useful here, set up so it's an OR command with either switch activating channel 7.

Yes.

[Andy J]

Frank, suspect you are correct but found the logic switch menu selections far too complex for a infrequent user of that particular function.

 

Will have a look on the FRsky site to see if they list any examples of software settings to get specific functionality but suspect there will be none.

 

Horus would be a nice system if only they could improve the User interface.

[GrumpyGnome]

OK,

 

This is what I have:

 

Channel 8 (the kill gizmo, assigned in Inputs to switch H (momentary switch)

100% Mix on channel 8 assigned to switch H

Channel 8 output set to 100%

Special function assigned to Switch F (up) with function of Override CH3 (my throttle channel) to a value that gives minimum tickover (trial and error needed here)

 

Switch H kils ignition; switch F 'up' locks throttle at idle so throttle stick has no effect. Switch F 'down' enables throttle stick.

 

 

 

[GrumpyGnome]

I also have voice alerts for any change of the switches above - Special Functions, Play Track, tracks recorded in Audacity (my wife even nags me at the field!)

FrOS was pretty much stillborn, and has not been improved for a long time. It won't won't ever be updated now, because FrSky have ETHOS and that can be applied to any X10 or X12. Whislt changing OS might not be what you want to hear, at least you have a pathway without buying a new TX, and ETHOS is getting very good reviews. Full details on RCGroups.

 

 

[Andy J]

Matty, certainly looks like what I want so will have a further read on RCGroups.

 

GG just about to have a play using your suggested config.  Certainly need some voice alerts but will have a LED indicating when the motor is alive. Like your idea of locking out the throttle as paid the price once when a 450 heli blades bit my leg. Shame as it was my birthday and a trip to the hospital was not what I wanted.

Having little luck using your settings GG.

 

First of all you cant assign a switch to a channel in Inputs that is done in Outputs is it not.

How do you override Ch3 in the SF mode? I thought the SF mode was to play warnings.

Lastly how did you combine switch H & F?

[GrumpyGnome]

OK, a bit more info. Bear in mind I use OpenTX so there may be slight differences (I guess you could jump to OpenTX to get full functionality).

 

In Inputs - I have channel 8 assigned to my kill device with 100% input, Switch H, named 'Kill'

In Mixes - I have 100 mix on 'Kill'

In Outputs - I have Channel 8 'Kill' with default values 

In Special Functions:

- SF1 is a voice alert for the plane name

- SF2 reads SF(up arrow), 'Override CH3' (my throttle channel), 17 (value that gives lowest idle), tick box selected (i.e. it's 'live')

[Andy J]

Well got a bit further towards obtaining the correct function by using the Throttle cut function in conjunction with Sw F on Aux 2,  Ch 7. Throttle and Ch 7 is now inhibited until SwF is set. Just need to add the momentary switch SWH which is currently assigned to Ch 10 but how I do this?

 

Also had a little play with the ETHOS PC sim.  Looks like what I had on my Spektrum DX7 but had some difficulty driving the simulator until I found what key did what on the PC keyboard.

 

Has anyone downloaded ETHOS to a X10S and can confirm it is better than the old FRSky OS in terms of simplicity of the User Interface as tempted to give it a go.

Hi all, I have a similar problem with the FrSky OS - Open TX is black magic to me at the moment - being forced to move from JR I thought the Horus x10s would be a good move, don't get me wrong I love the radio but do not find the system as intuitive as I would like.  Basic model setup is fine along with rate/expo, rates, fail safe etc, where I get confused is assigning switches to a channel to achieve a certain function, example I would like to use a 3 position switch for the following pos1 function off  pos2 ignition on engine at low idle for starting and landing, pos3 ignition on high idle for flight, would have been relatively simple on my old TX but I just cant figure it out on the Horus, just getting old and lazy maybe.

I would be interested to hear if the Ethos system is any simpler/intuitive really hate to keep changing radios/systems just because..

 

Tony..

[ken anderson.]

hello Tony, open TX is a bit/lot different to use...have a look on Google, there are some how to do videos which are helpful....

Really sorry Tony, but Frsky OS is a dead end now - almost no-one is using it, and it has been abandoed by Frsky in favour of ETHOS. If your set is capable of it I would update to ETHOS as the general view seems to be it is easier to use than both Frsky OS and OpenTX (at least if you are coming froma canned mixer style radio like JR). If it's not capable of Ethos then go to OpenTX - you may not find it easier initially but at least there is far, far more help available online. 

[Andy J]

Tony, this link may be a good place to start when learning all about the operating system. Certainly I struggled for a couple of weeks. Also you need to put the OpenTx simulator on your PC as you may find that interface is slightly easier to use and it allows you to see the outputs in regard to stick and switch inputs.

Tony the X10S will need to have two new cards installed to be compatible with Ethos. These are available from T9Hobbies at a reasonable price but you would need specialist soldering skills to be able to fit them.  Did wonder if T9 did offer an upgrade service but never talked to them regarding this.

well if you have a horus  why not try the new ethos operating system it's core seams to be based on open tx but with a user menu driven interface  , got positive feedback so far.

 

See here   i am looking to swap to it from opentx on my x12s.  i have just going to look at the basic simulator today and see.

 

I have all ready upgraded to the new 'ISRM Upgrade RF Board'  which is just a plug in job with a bit of unscrewing first.

 

I have not upgraded the 'para' board as I don't need the blue tooth features it gives (like wireless flashing of archer RX's etc). this upgrade needs a hot air solder gun.   all works well and i'm happy

Thank you all for your replys, yes I do understand FrOs is no longer supported and I do have a Taranis with Open TX but I do still struggle with it at times mainly because I only a dozen or so models  and I wish to fly them not mess around with programming a radio so my re programming sessions are few and far between.  I have considered upgrading to Ethos but have to wonder if all the bugs are out of it yet? like I said I want to fly not mess around with upgrading on a regular basis.  Sorry if I seem short tempered but our club rules have changed and instead of a simple switch to turn the igniyion on it is now a requirment that the ignition can be killed from the transmitter, I have an opto isolated switch running directly from the Rx - I run two 2600mha batteries to the rx one either end of the bus bar - but I cannot get the radio to program a channel to a switch to use as an on-off switch for that opto isolater alone.  Tried the throttle cut but to no avail, I may have to resort to my Taranis for this model as I know just about anything can be accomplished using Open TX.. I may yet move to Ethos.

For those offering places to send my radio for work I should perhaps point out that I live on the west coast of Canada and Aloft hobbies in northern California is the authorized dealer/distributor for FrSky in my part of the world and very fast and efficient with service and advice when needed.

 

Thanks again for all your help it really is appreciated and yes I'm an ex pat and yes after 45 years there are still some things I miss but every time I visit my village of birth a little more of it has vanished.

 

Stay safe stay well all of you, I will figure it out eventually..

 

Tony.

Have you tried the FrOS manual on the Frsky site? It looks pretty comprehensive…

This is the main FrOS thread on RCGroups, it might have the info you need…
