Elevator trim

[N222TT]

I have the Logitech Flight Yoke Throttle System. I've tried to program the trim but it won't let me. I have to keep the yoke pulled back about half an inch to fly level. When I let it go back to neutral the plane nose dives.

I'm not sure I know what you mean when you say: "I've tried to program the trim".

 

There are two ways to "program the trim", both are found at: "Control Options --> Flight Control Options --> Control Trimming surfaces.

 

There you will find the two ways to set trim that work (and two others that I see no reason for). If you want to use keyboard keys or switches such as the ones on the top of your throttle quadrant, then you assign "Elevator trim up (nose up)" and "Elevator trim down (nose down)" to the keys or switches you want to use.

 

What I think is a better way, is to use a slider like one of the three big sliders on your throttle quadrant. I use the right most slider for elevator trim (and I have flaps assigned elsewhere); you assign (with the Throttle Quadrant selected), Elevator trim axis (-100 to 100%) to Joystick L-axisX.

 

The way to check if elevator trim is working OK is to do it on the tarmac before you take off. Watch the trim surface while you change the trim.

 

Good luck.

A good visual check is to watch this gauge while cranking on your trim wheel. Set trim to zero before take off.

 

Hope this helps.

How do you get those indicators to show?

Exterior view - and I use the two thumb switches on the right handle of the yoke by the red button for elevator and aileron/rudder trim.

Depends on personal preference or what hardware you're using.

I use the Keyboard END key to toggle between exterior and interior view. The HUD view is managed here: General>Camera>Chase Camera>Instrument Heads-Up Display (HUD) On/Off

While you call it a trim problem, it sounds like it could be a problem with the 'neutral' position on your controller. You go into the Controls and then the section for your controller. Find the primary flight controls and then a series of adjustments will be displayed. Have your yoke at the neutral and then go thru the X-axis adjustments to get the flat zone for the neutral position to be in the right place

Hope this helps.

The elevator adjustments may also be a way to compensate for this.

One thing I didn't mention is I had a CH yoke and thought it was the problem doing the same thing so I ordered the Logitech.

I have the Logitech yoke as well and the elevator and aileron trim were already programmed to the two switches on the top right handle of the yoke.

My trim buttons are assigned 6 and 9 by default.

I assign 6&9 to landing gear.

I think you could be right about neutral position on my yoke. I'm going to try that. However I noticed when I use the trim wheel it goes back to neutral.
