Does anyone have an idea of what approximate settings need to be used for the 'balance spring' force

Does anyone have an idea of what approximate settings need to be used for the 'balance spring' force to balance out a given grip weight on a given extension length?

HextopiaOP•10/22/23, 4:27 PM

Or is it just the 'TFAR' method?

'try it and find out' is probably a good approach... but I'll just say that the "adaptive recentering" does a fine job by itself with my Alpha Prime grip sitting on a virpil z extension.

HextopiaOP•10/22/23, 4:35 PM

It did alright with a 100mm extension, now that I'm running a 32cm extension at anything beyond about ~50% of the axis in any direction it's drooping enough that it's screwing up autopilot in multiple aircraft

HextopiaOP•10/22/23, 4:36 PM

So some extra centering force is going to be needed

HextopiaOP•10/22/23, 4:38 PM

It also tends to oscillate sometimes, so some tweaks to friction are needed

walmis•10/22/23, 4:41 PM

My approach to find the values to balance spring is to disable the regular spring, so the stick is limp. Then increase the balance spring values in each direction and check if stick wants to fall when released at an angle. Once it roughly stays in place where you put it, then you're good to go.

HextopiaOP•10/22/23, 4:44 PM

Using that method, looks like I need about ~25% for balance spring to counteract most of the droop, which might explain why adaptive recenter wasn't quite cutting it

HHextopia Using that method, looks like I need about ~25% for balance spring to counteract...

walmis•10/22/23, 4:45 PM

Yeah, once you apply some balance spring, the adaptive recentering will have more authority and will not saturate as before.

HextopiaOP•10/22/23, 4:55 PM

I'm still running into an issue with oscillation in the X axis that tweaking the damper/friction forces isn't making a dent in

HextopiaOP•10/22/23, 4:57 PM

Reducing the spring gain map for the X axis can fix it, but I'm worried that will affect the droop issue in that axis

walmis•10/22/23, 4:59 PM

Can you show your settings?

HextopiaOP•10/22/23, 8:56 PM

I will when I get some time back at my computer. I'm going to test the settings I have right now and see how it performs, since I reduced the max gain in the X to eliminate the oscillation

amadeus•10/22/23, 9:56 PM

so i've noticed kind of an interesting issue, that i think my be a software thing, where the spring forces can seem to apply inconsistent force as you move towards the extremities of the movement. it's a bit subtle, but it does show up in my virpl graphs:

amadeus•10/22/23, 9:57 PM

basically it kinda feel like i hit a small amount of resistance bump before breaking through to the edge, this is close to the outer edge of the movement (this is with 100% spring strength, default gain map

amadeus•10/22/23, 9:57 PM

the other settings are pretty minimal, although even with them all disabled, it still was an issue (minus spring of course)

amadeus•10/22/23, 9:58 PM

also gain map in case you want to see that

amadeus•10/22/23, 9:59 PM

here's another example to show that clear change in resistance towards the edge

walmis•10/23/23, 4:48 AM

Hmm, it could be this is because of PSU power limiting - try increasing PSU current limit or reducing max motor current to 25A and see if this goes away

amadeus•10/23/23, 6:17 AM

increasing PSU current to 14 does seem to fix it, although i don't know if that is safe?

amadeus•10/23/23, 6:18 AM

(or at least -- vastly reduces it, it might still be there a little bit

walmis•10/23/23, 6:18 AM

I recommend not exceeding max current of the PSU, otherwise PSU over current shutdowns are to be expected

amadeus•10/23/23, 6:19 AM

what's max current of the psu?

walmis•10/23/23, 6:19 AM

9.5A iirc

amadeus•10/23/23, 6:20 AM

what's strange is that it only happens in the X axis, not the Y axis :/

walmis•10/23/23, 6:20 AM

Or you can reduce max motor amps to 28.

amadeus•10/23/23, 6:21 AM

so what exactly is happening? out of curiosity?

walmis•10/23/23, 6:21 AM

saturation

amadeus•10/23/23, 6:22 AM

28 motor max and 9.5 psu current do definitely get rid of most of it for sure

amadeus•10/23/23, 6:22 AM

there's still a bit, but it's much further towards the extremities, which makes it less likely to hit

amadeus•10/23/23, 6:22 AM

it is weird that the Y axis seems to have not of this prob though

walmis•10/23/23, 6:24 AM

Also force compensation could play a role here

amadeus•10/23/23, 6:26 AM

i definitely have much higher force compensation on the X axis

amadeus•10/23/23, 6:26 AM

150 on X vs 80 on Y

amadeus•10/23/23, 6:28 AM

but does make me wonder if there's some software level stuff that still could account for this and make it feel better?

amadeus•10/23/23, 6:28 AM

i definitely need 150 on the X axis, Y axis doesn't need it, not sure why

amadeus•10/23/23, 6:29 AM

if i drop force compensation down to 80 for the X axis, the problem does go away, but of course, i don't hit the max X value under 100% spring force)

walmis•10/23/23, 6:30 AM

I did some work on power limiting and force comp for the next firmware, so hopefully it will improve on this

amadeus•10/23/23, 6:30 AM

sick, i look forward to the next christmas drop (and by that i mean, anytime you release a firmware update it's christmas lol)

Reed•10/23/23, 4:20 PM

Nice

Reed•10/23/23, 4:20 PM

When we update the firm are all of the defaults also updated to the current standard?

Timmy•10/25/23, 5:43 PM

Hey, I just received my Rhino and it feels great to fly in Apache, but I noticed that it slides a bit forward (and stops) when I trim in negative Y position.
How can I fix it? I'm using TM Warthog stick without extensions.

walmis•10/25/23, 5:56 PM

Hey, you mean it sags a bit forward?

walmis•10/25/23, 5:58 PM

TM grip is quite heavy and you can balance it using the "Balance spring" feature, you can find a discussion here recently: 🧰support

walmis•10/25/23, 5:59 PM

Also "adaptive recentering" helps to keep the stick in the trimmed position

Timmy•10/25/23, 5:59 PM

I'll try, thank you

Is there a variable in TelemFFB to reduce engine rumble in fixed wing aircraft? I only see a switch to turn it on and off in the stock config file.

 engine_rumble_lowrpm = 650            
 engine_rumble_lowrpm_intensity = %8     
 engine_rumble_highrpm = 2800

Should work for DCS or MSFS (or IL2).. even if its maybe not in the default sim section

Subsonic•10/26/23, 12:14 AM

So....crazy thing I have seen sine the last DCS update....
Tomcat on deck before launch, wipe out the controls
Pull back on stick at a moderate to high rate....boom!....pitch motor takes a nap and base needs a power cycle to wake up
Odd since the only ffb forces are the basic spring and damper rates.

In flight, a rapid split S, not really slamming the stick aft...smae effect...nap time for pitch. Never an issue in roll.

Outside of DCS...I can whip the stick around and never an issue.

Subsonic•10/26/23, 12:14 AM

Subsonic•10/26/23, 12:15 AM

Does not seem like a current spike.....but maybe it is happening too fast to see in the software?
Thanks for consideration in advance...
