Hey !I was bored by fsx trim up/down stuff : I couldn't get my plane to a nice steady flight for long.So I decided to design a small soft that helps me with that.I uploaded it here : http://hotfile.com/dl/125076551/52b5c3a/Compensator.zip.html(it's in beta, that's why i didn't upload on avsim)Basically, if you launch this when FSX is running, you can trim your plane like before, then once you get something close to a perfect trim, you can trim more precisely with the rotation axe X (the one with the info button on the X52), or the one you want (see config.ini). Also, if you hit the button n29 [info button on the X52, but you need first to disable the help in X52 config panel] (or the one you want, see config.ini), the axe will be centred on the angle that you have at the moment [maybe not clear, sorry, English is not my native language...].You may notice that in config.ini, you can change 'delta' : it's the "range" of the axe around the center.Hope you will like it ;)Looking foward to your comments and feedback, and again sorry for my EnglishRegards,Ludo

Just curious, why not turn on the AP altitude hold (and AT speed hold if available) and let them trim the aircraft for you?Cheers,- jahman.

You don't have to do that in real life, you shouldn't have to do it in the sim.I usually just adjust the elevator_trim_effectiveness in the aircraft.cfg until it's to my liking, but I like the idea of being able to fine-tune the trim instead of one global setting. I hope the original poster will continue to develop this.

Apologies, I misread "elevator trim effectivebness" for just "elevator trim".Cheers,- jahman.

when you get close to a perfect trim you should trim more precisely with the throttle.Edit: On second thought this is only feasible if you have a throttle axis on whatever yoke/joystick you are using so you have fine-grain control!

Again, it's not what i do in reality... I choose the rpm I want then I trim.Jahman:what can I do if I don't have AP ? And I the AP is turn ON, I don't have to 'fight' again wind, turbulence...

Unfortunately FSX elevator trim will never work that realistically.For what it's worth I was taught these during my PPL training:P.A.T = Power, Attitude, Trim (use this when transitting from descent to level flight or making power changes whilst in level flight).A.P.T = Attitude, Power, Trim (when levelling off from a climb)Sticking to these certainly helps me trim out any elevator forces in a real aircraft (whether single, twin or turbo prop) and is effective in FSX.RegardsAdam

Just use trim to remove elevator stick/yoke forces. Period. That's what it's there for. (If in doubt, consider aileron and rudder trim are there for exactly the same reason: Remove control forces.)Now once you've adjusted elevator control forces to neutral, yes you can fiddle with the trim to neutralize creep climb/descent and so maintain constant altitude.Cheers,- jahman.

Well, I really can be as precise as I do in areal plane with this software;) Try it !

each FSX aircraft has an elevator trim effectiveness setting in its cfg file - its usually set to 1.0 if it is lowered to, say, 0.5 does this give finer "tuning" with each key or button press when trimming ?
