Question on A2A C 172 trim setting.

[Bobsk8 12,578]

I would imagine there are many A2A C 172 aircraft on this forum, I have a question on takeoff trim setting. I find that setting the trim in the takeoff  position results in a very high climb rate requiring a great deal of nose down trim after lift off to get the normal Vy speed of around 79 knots. I also find that if I set the trim so that the indicator is lined up with the bottom of the K in takeoff which is about -35% if I mouse over the trim wheel, , that the pitch is normal on rotation getting me around 80 knots for climb out. Has anyone else noticed this?

I noticed too like many other. According developper and 172R users, this is like in the real aircraft. This setting can also varied depending on whether you fly alone or with passengers, luggages and so...

I found out this morning, that the updates that had come out for the A2A aircraft, had not properly installed in my C 172. I had to delete a file, and then run the update again, and this time it "took", and now the trim behavior is much much better.

How did you know they were not properly installed?

Not directly related, but for anyone who finds the trim movement in the A2A's painfully slow, if you go to the aifcraft.cfg and search for

 

elevator_trim_limit

 

....and change the value from 100 to 19.5, this will give a similar trim moving speed to other GA aircraft in FSX/P3D.

I was told by a forum moderator that the behavior I was seeing sounded like pre-update. When I followed his instructions and ran the update again, a new aircraft.cfg was created, which I had not had happen in prior installs of the update. The aircraft handles so much better now.  Apparently what had happened, when I went from P3D 2 to version 3, and reinstalled my A2A aircraft, he folder already had an entry in this file  "   client .wyc file "                          that the update was run in Version 2, so it would not run the update again. I had to delete that entry in the A2A folder.

Better idea, if it is an A2A aircraft, go to the A2A configurator and program your trim joystick buttons in that. The trim movement is fantastic now.

Thanks!!! And now I finally know how to document ALL configure files

rudder_area =9.00000 //Square feet

elevator_up_limit =28.00000 //Degrees

elevator_down_limit =21.00000 //Degrees

aileron_up_limit =30.00000 //Degrees
