As some of us are building the Shannon Lifeboats using the FrSky X9D or X9E transmitters, I thought that we could exchanges programming tips, examples etc in this thread.
-
I purchase my X9e from Hobbyking, but had to get the X8R receivers by searching the net. They need to be the 'EU LBT' type, but they can be reflashed, according to youtube.

It's a mode 1, but can be changed in the program, and centering spring is available from banggood. Or swap the gimbles over.

More programming info please as I am struggling with getting my X9E sorted out for even basic control. For my new rescue boat, (twin jet drives but no bow thruster). Any help will be greatly appreciated.
Cheers Chris M

Only had mine for 24hrs, but this might help.

No matter what else you do, download the latest version of OpenTx .... https://www.open-tx.org/downloads (https://www.open-tx.org/downloads)
OpenTx includes Companion, a must have if you are going to program your own model, it includes a simulator and it is so much easier than programming on the transmitter itself.
Youtube is your friend with lots of video help.
If you are brave you can download my demo of a system for a Shannon from Dropbox...... https://www.dropbox.com/s/73529imvbcn14xj/Shannon%20Demo%20file%20set.zip?dl=0 (https://www.dropbox.com/s/73529imvbcn14xj/Shannon%20Demo%20file%20set.zip?dl=0) and https://www.dropbox.com/s/x8cs9qald0wh1ck/How%20to%20successfully%20install%20a%20model%20from%20OpenTx%20Companion%20to%20your%20transmitter.pdf?dl=0 (https://www.dropbox.com/s/x8cs9qald0wh1ck/How%20to%20successfully%20install%20a%20model%20from%20OpenTx%20Companion%20to%20your%20transmitter.pdf?dl=0) Click the download link next to the sign in button

To save me a headache,
Twin motor boat.
Has anyone set up a transmitter to slow the inboard motor when turning?
-
Do you want:-a) the power reduction to be proportional to the rudder movement
b) a fixed power reduction once the rudder has moved by greater than "x"
c) the motor to stop once the rudder has moved by greater than "x"
-
The first one would suffice please.
-
Go on, pick the hard one %%
I may be gone some time.
-
not exactly what you want, but close, and extremely simple.
this will actually increase the outboard engine, and decrease the inboard engine. to do exactly as you want (only decrease inboard engine) will require throttle curves... if you want that, i can put that in an additional post.
this assumes you are starting with a blank model with no mixes.
go to your mixes page
add a mix to channel 1, use AIL for source, set weight to 100%
add a mix to channel 3, use THR for source, set weight to 100%
add a mix to channel 4, use THR for source, set weight to 100%
to channel 3 add an additional mix which uses AIL as its source with +30 for its weight
to channel 4 add an additional mix which uses AIL as its source with -30 for its weight
if the throttle drop/add doesn't give enough kick, or gives too much kick, adjust the weights on the additional mixes for channel 3 and 4
if you want to have a separate throttle steering from the rudder steering, use different source for additional mixes on channels 3 and 4. i will use RUD as my source on 3 and 4, and AIL for my source on steering, so that i get engine steering on the left stick, and rudder steering on the right stick.
-
If the model has Jet Drives ( Shannon etc) then both motors at the same speed provides a tighter turn than slowing the inner motor down.
Ok, try this "curves " option for proportional control.When rudder is within 25% of centre then thrust for both motors is controlled by " Thr "output. Outside that band, thrust is proportional to Rud for the motor on the inner side of turn, while the outer motor remains under Thr control.
Inputs
I1:Port Motor Thr Weight (+100%)
I2: Rudder Ail Weight (+100%)
I4:Stbd Motor Thr Weight (+100%) This puts both motors on the same Input - change Thr to use another Input
Curve CV1 3 point linear curve 0, 100, 0 output is proportional.
Logical Switches L01 a<x V1= I2:Rud V2 = -25 When rudder movement exceeds -25% then L01 is set
L02 a>x V1=I2:Rud V2 = +25 When rudder movement exceeds +25% then L02 is set
Mixes
CH1 I1 Thr Weight (+100%) :=I2 I2:Rud Weight (+100%) Switch (L01) Curve (CV1) When L01 is SET then replace Thr with Rud using CV 1
CH4 I1 Thr Weight (+100%) :=I2 I2:Rud Weight (+100%) Switch (L02) Curve (CV1) When L02 is SET then replace Thr with Rud using CV 1
Adjust Outputs as necessary
Comments please.

Thanks for taking the time to put this together.
Mix is for a Taymar lifeboat.
I'll put it in 'tx companion' and see what happens.

@kinmel
motor reduction should only work in forward, set lo3 for forward flag, lo4 reverse flag?
if throttle in centre, and rudder moved, then motors start up
-
logical switches.
Lo1 a<x I1:rudd -25 Lo4
Lo2 a>x I1:rudd 25 Lo4
Lo3 a<x I3:Thro -25............reverse
Lo4 a>x I3:thro 25 ............forward
no effect on motors if throttle under the 25 offset.
rename attached file to .otx
-
We are both learning together, it really is challenging to get all the parameters sorted.
Thanks for the update
-
@Old Fart
Lo1 a<x I1:rudd -25 Lo4 Should this read Lo3 not Lo4?
Lo2 a>x I1:rudd 25 Lo4
Lo3 a<x I3:Thro -25............reverse
Lo4 a>x I3:thro 25 ............forward
-
Lo4 is motors in forward mode.
Lo3 is motors in reverse.
-
Lo4 is motors in forward mode.
Lo3 is motors in reverse.
It is not working for me.
Where do you use Lo3 and Lo4 in the mixes?
Can we swap email addresses via PM and then we can send the model files, rather than text to insert?
-
pm sent.
change .txt to .otx I think thats the extension.
use Lo4 in the logical switch setup.
-
Your version runs correctly in the Sim, so that is another module in the library.
ThanksAlan
-
Add the SF switch to kill the drives. it's labelled 'FkIt'
-
You will get an even faster turn if instead of just stopping the inner motor, you reverse the motor at full rudder.
Try changing CV1 to -75,55,100,55,75.
-
I was thinking the same thing, thanks.

above reverses only one side.
-75,55,100,55,-75.

yes it does ! missed out the minus sign when posting, it's in the Sim.
Sorry <:(
-
Trying to get my head around this.
X9E
Using TGY_CVT01 voltage sensors.
If 'read voltage' < 4.00V then radio speaks 'Port Stopped'.
-
Is the input voltage dropping below 4v ? If so the unit automatically switches off and the Port will stop.
Voltage Range: 0~100V DCAccuracy: +/- 0.1V
Input Voltage: 4.0~6.5V
-
Not what I'm requiring.
5v for RX's and Servos is from a separate battery source.
Red leads from ESC's are disconnected.
ESC's have a single push button for on / off.
Flick switch on X9E to start ESC, further flick switch to stop ESC.
By monitoring the red lead will show if ESC is on or off.
Hope that makes sense.

Found sensors in my junk box, to read motor rpm and temperatures, using the Smart Bus
-
RPM, Current, lipo and gps sensors all working to the smart port.
sbus to pwm module works, but not using it at present.
Problem I've got is reading sensors into the sbus and showing on the x9e.
Been searching sbus & x9e but only get the sbus to pwm module.
Do I need to enable sbus inputs in a menu?
-
sensors do not go into the sbus, they can only go into the s(mart)-port
-
That's a shame, the I6x TX/RX setup uses the sbus for sensors.

Flysky != FrSky
but seriously, telemetry/sensors are the "wild west". all the different manufacturers use different telemetry protocols, some have more than one (FrSky D series is different from X/L/R series), and they all use different methods to get the data back to the receiver. to the point where you will not be able to use a different manufacturer's sensors. Castle Creations make Speed controls that work with Spektrum OR Futaba, but to do so, you need an adapter (unique to the brand of transmitter) that costs as much as the speed control. One of the reasons i went with FrSky is because their sensor lineup is very large, and inexpensive. it also doesn't hurt that their protocol has been reverse engineered, and one can create unique/new/different sensors using an arduino.
from what i have just read, the sensors for the 6 channel flysky receiver will not work with the 10 channel receiver !?!?!

@kinmel,
Presume using mixes > 16 due to only being able to select one switch.
I originaly moved the mixes to ch28-32 to release ch17-27.
Now I'm looking at removing these mixes.
Using Logical switches.
CH2:Pbucket
L02 AND SFdown SDup
L03 AND SFdown SDmid
L04 And SFdown SDdown
then putting in Mix2
thoughts?
-
I used the virtual channels for mixes because that way it was easier to understand what was happening when mixing 3 switches with 6 inputs to manage 8 outputs and 9 curves. All while knowing nothing.
Since then we have started using logical switches and it does streamline the process, so it is worth making the changes.
I have not done much with Open TX lately, now trying to master 3d printing. Once the weather improves and the Shannon is back on the water, I will start tuning the boat's handling.
-
Only took me 2 years and 3 3D printers to get a suitable printer, good luck....

Does anyone know where I can get this part for a x9e?
It latches the retractable legs in place.

The Ebay link looks promising, ordered a pack.
Thanks Andy.

Update: That last link did the job. Fitted in no problem.

Great Dave I ordered too :-))

I upgraded mine to the metal arms and since then one has released itself spontaneously. Hoping this will fix that.

Is it possible to alter the servo travel speed on the Taranis X9E ?
John

Yes, it is OpenTx firmware.
Open the "Mixes" tab and select the channel, a box at the bottom left is an option for Slow Use trial and error to get the values that suit your need.
