Rudder output max range for the right being reduced when starting the Mi-8 simulation

[Horizon Line]

Hi, I'm enjoying very much the bird, eventhough I'm more of a fixed wing guy.

 

Something caught my attention and very much bugged me on my first hours flying this beta.

 

For some reason, the module is overriding/reconfiguring or leaving out of alignment my stick's rudder values to the right.

 

I pretty much know that pedals are the recommended, but in my country, stuff are hell of expensive and I just got back into DCS by a couple of months ago, so my only choice is my flight stick twist for rudder.

 

When I launch the module my rudder max range to the right reduces by ~15%, even when I leave the sim. It only comes back to normal when I unplug and plug back my stick's usb. On other modules everything is just fine to the left and right.

 

Note: Middle position keeps aligned, only max input to the right is reduced ONLY because of this module and keeps like that outside the sim only comming back to normal when I unplug and plug my stick back on usb port.

Here are screens out of the sim on the same stick twist position before and after running the module.

 

Great beta so far, but this issue is quite breaking excitement for me.

 

Edit: I have the P-51D, A-10C & A, Su-25 and the Black Shark 2. None of them start this issue.

 

Good Flying

Disregard this thread. Something funky going on in my end, and weirdly enough, the module was increasing indirectly the issue by it's nature.

I have also observed this strange behavior. My pedals (are perfectly calibrated) lose part of its travel, usually 25% of the way to the right.

At first I chalked SPUU-52 system, and I gave it as valid, but on occasion I have lost almost total right path

 

Today I discovered that it is possible to "recover" the total travel, playing with the "Z-X" keys.

Right. I unbecoming of writing.

It is an old problem, it seems incredible that take a few hours with the Kamov, and also a user of G940 and pedals without spring. :doh:

 

 

This is the solution that provided PeterP for Ka-50:

And this my adaptation (hopefully temporary BST) for the Mi-8. There is no merit, it was a copy-paste.

Ok I'm going back to unsay

The Mod PeterP, is completely unnecessary.

 

It is true that the range of the pedals will cut, the cause is the AP heading channel. With the channel heading off, the pedals maintain their full range.

If you remove power to SPUU-22 the range is reduced even further.

 

Does anyone know how this actually works?

The SPUU-52 system limits tail rotor pitch in higher air densities. So at low altitudes and temperatures, you will have less right pedal available. This is necessary because the Mi-8MTV-2 has been optimized for hot temps and high altitudes. When lower and colder, there is actually enough tail rotor pitch authority to damage the aircraft if you don't limit the pitch with the SPUU-52.

Is this (or will it be) modeled in-game? If you turn the SPUU-52 off, can you damage something?

I don't know, but I agree it would be a good thing to test next time I get a chance! Or anyone else, of course.

The situation is as follows:

At sea level, if you connect the "Heading channel" of the AP, the system starts cutting stroke of the pedals. Specifically right side.

If you do not select this channel (Heading) the path is complete, at sea level.

 

If you disconnect the "channel Heading" the limitation persists. Although all AP disconnect.

 

Remove power to SPUU-52 cuts on both sides of the pedals. Which is reasonable.

 

The only way to recover full travel in the pedals is making a "neutral trimmer".

 

I understand the SPUU-52 is active but not functional damage model, I've been doing wild maneuvers at sea level, to test the path of the pedals, and I have not broken anything.
