Trim for Aeroscout trainer plane

Just got RF Evolution (Steam version) and am using it with my Spektrum NX8 radio via wired USB connection. All seems fine except for the trim. I am following the flight training tuts which are pretty good actually. When I fly the Aeroscout which is the default trainer plane, and I keep the throttle at, say, 50%, it still tries to climb. I'm having to keep up elevator the whole time for level flight. I'm using SAFE like the instructor has us do. I adjusted the elevator trim and I can see the trim affecting the sticks in the little radio picture in bottom right (when I enable it for my flights from the RF menu). But there doesn't seem to be any real difference in the aircraft flight.
This could just be how the physics works for that plane but I'm not sure. The plane seems to fly level for the instructor.

I learned to fly in 2019 for reals at our local club field but stepped away since early 2020. Heading back to the field but I decided to get a refresher with RF first.
 
SAFE is fighting your trim. In that mode, the plane should fly level at 1/2 throttle (stick centered). Higher and it will climb, lower descend. When you add trim, SAFE senses the change, and compensates.

With Intermediate, it still helps a little, but not as much. And in Advanced, not at all, so trim is fully effective.

Make sure your radio itself is calibrated (on the radio: System Setup > System Settings and scroll to Calibrate). And then again inside of Real Flight go to its calibration (Settings> Controller> Configure Controller> Calibrate) and go through the same kind of steps. Without doing those, where electronically your stick is at may be off. In real life if the radio isn't done, you'll have all sorts of problems with things not knowing what the actual high/low/middle points are for each stick movement. Rarely needs to be done on the radio again - usually after a software upgrade or hardware repair. Good to do once in a while (once or twice a year?) just to make sure. Other brands may have an issue with extreme temperature changes and need it done for times when winter flying vs summer flying. For RealFlight, probably never again unless you change controllers.
 
When you calibrate sticks, make sure your trim is set to zero (centered) during that process.

I just gave it a shot. It seems to fly straight right at 50% throttle. It doesn't take much more than that to start climbing.
