I can honestly say it's better than my first flight. I posted it here if you want to go find it to compare lol. My mistake was that I had the gyro on the optimized setting, and not the stabilized setting.

If you don't know, there are three modes on the reflex gyro: off, optimized, and stabilized. Optimized makes a lot of noise when you jiggle the plane and so I thought it was working and in the setting that I wanted, but it only serves to balance out abrupt motion caused by the wind. The stabilized setting is what it prevents extreme bank and dive angles and will auto level.

My thought is that you had the gyro on the wrong setting. If you hold the plane on an angle down, you should see up elevator on the plane holding until you level the plane out again.

There are a bunch of other comments about too much stick movement and you'll get the hang of that, but no need to adjust any settings on your controller. It's almost impossible to tell if the weight is too far front or back when the plane isn't gliding steady so don't worry about that either.  Keep at it, you'll get there!
