I purchased my medium whoop (inductrix fpv plus) a few weeks ago and fell in love with fpv. I would almost say borderline obsessed. I found it very odd going from years of self level and only mild Acro line of sight flying to fpv. Started off very slow and steady in level mode and would struggle even at doorways in the house. As I started to get better at the immersion of fpv I started getting more brave and would attempt acro here and there. However acro LOS is far different and my abilities we're still limited to hold on and pray it didn't do anything quickly.
I since then purchased the spektrum USB dongle to pair with my dx6 and bought liftoff to start practicing. I started off helpless in the simulator and struggled even through the tutorials honestly. I've only clocked around 6-8 hours in simulator, by comfort with flying is exponentially better. I'm not ready for a full course of gates, as I'm not as precise as I need to be, but I can definitely fly the bird rather than holding on and praying. I'm still learning and will be for many many many hours to come, but with that being said a simulator can do wonders for your piloting skills. And it will roughly translate about 90% into the real world.
