This fascinates me too Pete. To be honest, I wasn't aware that some turboprops require trimming despite the fact that the AP is engaged.

 

Seems weird in regard to a modern aircraft and modern autopilot.

 

You have to remember that there's over 9,100shp twisting this baby over in the air.  The yaw is caused by the P factor.  Anybody that has flown any prop plane for more than 5 minutes is well aware of P factor.  I have found about 8 clicks of right rudder trim is sufficient to counteract the p factor at takeoff power.

If you have a yoke, you can assign the rudder trim to the right/left arrow keys on the keyboard which are not being used by FSX.

 

Just assign them in FSX Controls, no need to involve FSUIPC..

Hi there,

 

I'm mostly a heavy iron and really small GA flyer, although IRL I'm a low time PPL. Lucky me I have not experienced any of the problems others experienced, and I do feel particularly bad for those who purchased but can't activate. Hang in there, this bird is worth the wait!!

 

Yesterday, for the first time in my 15+ years simming, I've experienced my aircraft flying croocket, it looked and felt like it was flying left wing low (or right wing high) during cruise. Winds weren't too stron, I was on autopilot with YD engaged.

 

Then I found out during some research that this bird requires aileron/and or rudder trim while operating on AP, is that true? I know IRL some turboprops require that but I don't think I've ever seen it modeled in fsx, but I could be wrong.

 

If anyone has more info (I have not read through the whole documentation yet) I'd appreciate it.

 

This bird will bring thousands of hours of joy, can't wait to fire it up again.

 

Cheers,

Pete

 

Totally correct Pete!

 

This plane was designed with an absent/fake yaw damper. I'm half joking. Just like a conventional prop, you'll need slight rudder on takeoff, and on descent- left rudder at times. You'll find yourself trimming frequently for every power change- the real aircraft is like this too.
