ataribaby Posted September 23, 2019 Share Posted September 23, 2019 Hello, Recently got L-39 module and Kursant campaign and I found FM to be very sensitive - without any curves set to my Warthog even slightest movement of stick causes big pitch movement. I checked elevator surfaces movement with external view and this seems to be normal and inline with stick pitch deviation. It is just FM that is so sensitive. I can't believe that slight elevator angle can produce that big pitch change. I was unable to control jet till I set curvers to about 30. Is this normal or there is something fishy with FM and latest Open Beta? Link to comment Share on other sites More sharing options...
Nooch Posted September 23, 2019 Share Posted September 23, 2019 I was unable to control jet till I set curvers to about 30. Is this normal or there is something fishy with FM and latest Open Beta? No, it's normal. It's you man. I'm flying the L-39 right now and I'm perfectly able to fly the jet with no curves at all. It's just a sensitive plane by nature. It's made that way. If you find you can't control it, just practice and you will overcome it. To explain a bit, what makes an aircraft sensitive is the position of its center of gravity in relation to its center of lift. A plane like a Cessna will have its center of gravity forward and thus won't feel twitchy at all. A military jet or aerobatic plane on the other hand will have their center of gravity more aft, making them a lot more sensitive to elevator input. Modern jets like the Hornet, Viper, Mirage, etc, have built-in stabilization algorithms and basically help you control the aircraft easily. The L-39 doesn't have that, and that's why it feels very twitchy. But again, it's just a matter of getting used to it. [sIGPIC][/sIGPIC] Link to comment Share on other sites More sharing options...
ataribaby Posted September 23, 2019 Author Share Posted September 23, 2019 Thanks for answer. I see your COG argument now. I go then to get some stick time to get used with her. What do you recommend? Keep my curves or set it to zero? Link to comment Share on other sites More sharing options...
Morpheus Posted September 23, 2019 Share Posted September 23, 2019 You have to set curves, fly and fly again, with the time you will find YOUR good settings, it's the only plane I fly in DCS (no time for others :music_whistling:) and with practice you will get skill with it. :smilewink: Link to comment Share on other sites More sharing options...
ataribaby Posted September 23, 2019 Author Share Posted September 23, 2019 I will try. Kursant campaign is great to learn her. Link to comment Share on other sites More sharing options...
JG14_Smil Posted September 23, 2019 Share Posted September 23, 2019 Hello, Do you trim your aircraft? Very important. Best wishes. Link to comment Share on other sites More sharing options...
ataribaby Posted September 23, 2019 Author Share Posted September 23, 2019 Yep I trim her. For me it is very sensitive near center. Even slight movement of my Warthog stick in pitch results in big pitch command - I solved it to set pitch and roll curves to 25. It is not some warthog setting or so - all other modules are fine. As said, I probably need find sweet spot curves for me and get some time with her. Link to comment Share on other sites More sharing options...
Morpheus Posted September 23, 2019 Share Posted September 23, 2019 If you can, buy an extension for your Warthog, and put it in central position, this will help you for all planes. Begin with 10cm. Link to comment Share on other sites More sharing options...

ataribaby Posted September 23, 2019 Author Share Posted September 23, 2019 Yep I have 10 cm extension. Thanks for diagram. I have pitch amd roll dead zone set to 3. (Warthog doesn't need big dead zones) I will try bigger form diagram. Link to comment Share on other sites More sharing options...
ataribaby Posted September 23, 2019 Author Share Posted September 23, 2019 Yeah that values from picture is sweet spot for me. After few flights I adapted from FBW realm to this beautiful bird. Thanks all for help and suggestions! Link to comment Share on other sites More sharing options...

msalama Posted September 30, 2019 Share Posted September 30, 2019 There's no single correct answer to this. First, you'll learn to avoid any excessive inputs with curves anyway and second, some short-throw sticks are so unstable and overtly sensitive that you'll just end up all around the place if you don't use them. So with some controllers curves are actually a must, although it's always better if you don't have to use them. The DCS Mi-8MTV2. The best aviational BBW experience you could ever dream of.

ataribaby Posted September 30, 2019 Author Share Posted September 30, 2019 Yeah, just personal preference. Just using curves from pic pasted here earlier and it is sweet spot for me. Learned to fly her and it is joy now. Link to comment Share on other sites More sharing options...
Кош Posted September 30, 2019 Share Posted September 30, 2019 Have a Virpil stick with mount, so elbow rests on my leg as it would IRL. L-39 feels like a bus, with no curves. Hog travel is too short imho. Also, it definitely should not be on the table. Put it aside like on F-16 or get a mount. ППС АВТ 100 60 36 Ф < | > !

Morpheus Posted September 30, 2019 Share Posted September 30, 2019 +1, stick position/ergonomy is very important. Mine is in center position with 20 cm extension. I fly in a cockpit :smilewink: Link to comment Share on other sites More sharing options...

Кош Posted October 1, 2019 Share Posted October 1, 2019 Yep I use 10cm extension and table mount so stick is between legs :) You should be good with this setup if the stick is not malfunctioning. Set no curves and practice. Fly circuits and routes. The key to success is better fly for 40 min 3-4 times a week than 3-4 hours once a week. Let your brain get used to it.
