This are the (new) Support Forums for FSUIPC and related products.

These forums replace the old support forums which have been running for 20+ years. The old forums contain a wealth of information on all FSUIPC products, and are still available (until the end of the year) for read-only here.

At the moment these new forums are quite empty – I will be updating the FAQ section and copying across the User Contributions from the old forums in the next few months.

Surface trim: Elevator, Rudder and Aileron

I want to share my lua script for trimming. It works as follows:

 

To a button assign the control "Lua Surface Trim" after you have copied the file into your FSUIPC folder. The Parameter entry consists of 

100000 for Elevator trim

200000 for Aileron trim

300000 for Rudder trim

 

To this add the amount you want to trim:

1 for very small trim

a maximum of 16383 for full trim

 

add this to the base:

 

100000 + 300 = 100300   that would be a moderate trim up for the Elevator.

300000 + 2000 = 302000  that would be a large trim for the Rudder in one direction.

 

To trim to the other direction just make the number negative (-100300, -302000)

 

In order to center the trims you use:

100000  center Elevator trim

200000 center Aileron trim

300000 center Rudder trim

 

This is very handy as you can have different trim amounts for different aircraft. I even use small trims and large trims simultaneously.

Feel free to use this script to your likings.
