@dshaw I am learning to fly quads FPV and LOS at the moment. I found acro trainer pretty hard LOS, it’s easy to lose orientation especially when rolling sideways. Basically the difference between Acro Trainer and auto level is that acro trainer requires you to make a counter move with the sticks to change the control input, it doesn’t level as soon as you let go or centre the sticks. It still has an inclination limit, you can change the angle in Betaflight, so that can help.
I have a mode switch set up with Level, Horizon and Acro Trainer on my TX to switch modes, I have been flying my FPV learning flights in Horizon mode, which allows greater angles of movement that auto level. Next month once I have more hours on I will switch to acro trainer.
Setting up rates made a big difference, I have just copied Bardwell’s racing low rates and freestyle rates, again put on a switch.
Psyborgs rate settings for the Gremlin are bound to be good! Having a smooth, less twitchy set up will help a lot with first flights.
