Question:
The airplane has to be trimmed BEFORE applying the gyro?
It doesn't HAVE to be trimmed before installing the gyro but it's not a bad idea to have test flown the model so that you know what dual rate settings you like, etc, before enabling it. When I installed a Cortex in my X-Treme Jets Hawk 100, I went ahead and used the control surface travels from the instruction manual. When it was test flown, It ended up the Ailerons travels were WAY too sensitive to suit me so I ended up reducing all the dual rate setting, especially the high rates and then repeating the Cortex setup process before
ever enabling it in flight. It worked out fine in the end.
