Setting up Rates and Expo in FrSky ETHOS
Vložit

- In this video we look at how to add Rates and Expo in FrSky ETHOS. Rates allow you to decrease the amount of movement on the control surfaces. Whereas expo makes the movement of the sticks closer to centre have less effect. In the demo, I add rates and expo to the ailerons. But, the process is exactly the same to add them to other control surfaces. I demonstrate with switch SE. But you can use any switch you want.

Excellent job, thanks again!
Thanks Your videos are great
Thanks Steve 👍🏻
It took me awhile to get my head around this, as I have a Horus X10S Express that I recently acquired - used. It had OTX on it and I just was not able to make head or tails with it. Had it upgraded to ETHOS, but was unable to find tutorials for this system. Thank goodness that the procedures are nearly the same as with the X20 - just a lot more dial twiddling. Keep up the fantastic work!
ETHOS is pretty similar to OpenTX thankfully. The biggest thing for me is having to get used to not having the inputs page. I always found that really useful for clarity. Though there are lots of areas where it is easier.
Always thank you^^
Many helpful Ethos vids thank you. Maybe show how to setup reverse thrust for EDF's with reversing ESC? There is a separate signal wire going from ESC to channel for controlling reverse function. Adding this channel and mapping to switch make it reverse but you still have to move the throttle to max. Am trying to figure out how to make throttle go to max when reverse thrust switch is activated and back to zero throttle when switch deactivated. No luck so far. Throttle acts all weird or won't work if I try to make it do this. I know it's possible of course.
That was great Darren! 👍 Q: Could you do an additional demo including flight modes and specific rates per flight mode?
Hello, thanks for answering my questions. I bought a TD R10 receiver for my X20S. What power should I use for the 900MHz? The default 10mw? Or the max 500mw? It's for a glow rc airplane, not for fpv or drone. And i'm not using external antennas on the X20S.
10mW will be fine for a line of sight plane. It will be able to go further than you can see on 10mW. If you feel uncomfortable, then you could go up to the next power level. But it shouldn’t be necessary. I have heard of 10mW on ACCESS 900MHz going tens of kilometres.
If using the internal antenna on the X20. Mount the 900MHz antenna horizontally in the airplane. The 900MHz antenna in the X20 is located in the handle. For the 2.4 side I would have one horizontal (other direction to the 900MHz) and one vertical.
@@MrD Okay, thanks. and another question, what is built-in voltage sensor? td r10 has this voltage sensor, this shows the voltage of the rx battery on the radio? The TD R6 doesn't have it. Or the TD R6 can show the RX battery voltage on the radio too?
Thanks Daren, videos very are super helpful. Would love to see a video on how to move the rudder to the right stick for those gliders that don't have ailerons. I've had to use the rudder aileron mix, is there an easier way where the left stick is not rudder active?
I just plug the rudder servo into the aileron channel. I’ll also mix the rudder stick into the aileron channel if I think my instincts will kick in when the plane is on the ground.
@@txkflier Good idea,assume you assign ailerons to one channel. I was hoping there was a program step to assign the rudder to the right stick without changing the transmitter mode.
Thanks Daren That's a great video
Do you know how to set up 2 servos on a Single wing so they are balanced correctly I've been looking everywhere and I cannot find it for frsky
@@darrylplumer3877 In the new model setup wizard, you tell it how many channels to use for ailerons, elevator, etc. Once the model has been created, go to the monitor screen to see which channels move when you move the sticks. This will tell you which channels to adjust for reversing, sub trim, and travel for each servo.
Thanks it works well.
how can I add more rate in one side than the other? like I have one servo for both ailerons, but I want to add more rate in one side than the other
I don’t really follow you. But I guess you’re talking about differential. So, for example, there would be more aileron up than aileron down. The only way you may be able to do this with a single servo is mechanically. Possibly with a special servo horn where the holes are not straight across; but slightly swept forwards. You can only set up differential in the radio if each aileron has its own servo.
Hi Daren I have a question I have a RX4R receiver that i up dated to ACCESS using a newly acquired X18S and have found there is no S BUS output I used a toolkit M6 to confirm am I missing something ?
This receiver has SBUS IN and SBUS OUT. There are some solder pads, opposite the bind button. If you check the manual, it shows you what those 6 pads are for. www.frsky-rc.com/wp-content/uploads/Downloads/Manual/RX4R/RX4R%20ACCESS-Manual.pdf
@@MrD This receiver comes with 4 servo out puts plus a nice little set of leads that plug into a socket on the board for - + sbus AN2 sbus out sbus in the first three have a std servo plug /socket the rest singles. I swapped the two sbus leads and got an output but unstable. Why two sbus outputs ? 🤔
You shouldn’t use both SBUS connections. Only the one you need to use.
another question, I don’t have weight / rate in throttle so I can’t setup the servo in my glow rc plane… what i’m doing wrong?!
There is an option to change the trim to a low trim, for setting the idle. You can also use a curve to set the overall throttle. Or, set the endpoints of the throttle servo movement using the endpoints on the outputs page. There are a couple of options.
Ok, I will try to explain what I need: My airplane is a glow engine rc plane, and I need a throttle cut. The engine is cutted 100% when the throttle is 100% down and the trim is 100% down too. I need a mix that when I press a switch, it puts the servo on this state: 100% throttle down and 100% trim down, besides what trim I'm using or what % of throttle I'm using.
Its better to move in on the servo horn than to add expo
They are for 2 different things. Moving the control linkage will change the amount of throw that the control surface can move. It is best to set the maximum amount of throw using the control linkage. This shouldn’t be a wild amount. But the recommended maximum. They’re usually in the airplane manual. After that, you can reduce the throw further using rates, for if you want to fly more sedately.
Expo alters the movement curve of the stick in relation to the control surfaces. When you add expo. If you move the stick at exactly the same speed from the centre, out. The control surface will move slower when closer to centre stick, but quicker at the end of the stick movement. Expo is to give you more fine control around centre stick.
