Elevator Trim


Recommended Posts

My elevator trim control assigns and calibrates OK under 'Joystick Calibration', but works in reverse.

Forward or clockwise rotation of the trim wheel produces identical movement on the cockpit graphics. However, the effect is 'nose-up' trim instead of 'nose-down' (and vice-versa).

Checking the 'Rev' box under 'Joystick Calibration' has no effect on the problem. Neither does checking the 'Reverse elevator trim sense' box unser 'Miscellaneous' The latter function is said to be overridable in the 'INI file'.

What is the 'INI file' and where should it be located ? (The aircraft in question is the A2A Spitfire.) Any assistance would be appreciated.

Regards- Robert

I moved this from the FAQ subforum (which is where useful information is collected for users) to this, the Support forum. Else it won't get dealt with!

Do you think the aircraft designer made the graphics wrong?

It sounds like you are misunderstanding the trim. "Nose down" movement is with the visible wheel edge moving up, and vice versa. Think of the trim wheel looking sideways to it. The forward (hidden) part of the wheel moves UP like the nose whilst the rear moves down like the tail. The wheel is moved in the way you want to change the aircraft attitude.
