L-39 Trim Not Working

[TheFlyingGear]

Hi with the most recent update my trim does not work, I tried different key binds and the trim hat in the aircraft itself even moves but the trim does not change pitch or roll even though the hat is moving. I also had this issue arise in the prior update in the A-10C but it seems to have gone away. If anyone can get this info across or provide a fix! I am on open Beta btw.

Strange. Works on my end flying the ZA at least, just flew an op and everything was 100% OK.

I was trying to learn the L-39 today and noticed that the Elevator trim was working on the starboard elevator only. Has anyone else reported this or have noticed it?

 

I use TM HOTAS and everything is working properly. The trim switch on the stick in game is moving properly and the right elevator is the only trim moving.

The trim switch on the stick in game is moving properly and the right elevator is the only trim moving.

That is the correct behaviour. The right elevator tab is for 'regular' trim adjustments, the left tab is for automatic pitch compensation when moving from half to full flaps.

 

Note: Unfortunately when using a regular joystick like the TM HOTAS, the stick position doesn't change (due to aerodynamic forces) when changing from half to full flaps (unlike in the real plane or when using a FFB stick), so the compensation tab causes a pitch up in DCS, rather than compensate for a pitch down.

 

IMHO it's probably one of the few areas where DCS differs significantly from IRL L-39 behaviour unless using FFB.

I just bought the L-39 and cannot get the trim to function.  This thread is old enough I would think this issue was resolved.  Is there a work around?  I do not have a FFB joystick.

Any and all help would be appreciated

Haven't flown the aircraft recently, but it worked fine last time I checked.

Absolutely no problem here, fly it one hour ago on 2.7.8.16140 and all is ok. Check easy flight

I'm flying in stable right now and no problems with the trim. As @Morpheus suggested. Check if easy flight mode is on and re-check button assignments for elevator trim and trim reset. maybe there are some double things preventing the trim to work for you.

Also make sure that you're assigning to the correct aircracft, L-39C and L-39ZA have separate set of controls.

I’ll check the easy flight mode, everything else is as it should be. I’m thinking about reinstalling the mod and if that doesn’t work I’ll try removing and reinstalling DCS and start over.

My bad, I guess I didn't express correctly, so easy flight mode should be "OFF", as in "ON" it will take over some control functions.

Got it!  Deleted the mod and reinstalled.
