HeyExpo is a personal feel adjustment. Blade recommends 40%. 20% works for me but everyone is different. For me 20% is enough to smooth out my panic moves keeping me from over reacting.
Throttle curve setting for normal and FM1 are Blade recommendations. I changed FM2 for my liking. I never fly in normal and hardly ever in FM1. I take off and hit FM2.
These setting are close to Blade recommendations and should be a good starting point however probably will need to be tweaked to the pilots preferences.
I once had a professional pilot setup one of my bigger helicopters. I watched in amazement as he flew my heli like it never had are ever will fly again. I was so excited to try it out after he was done. Well I did not like it at all. Maybe if I could fly like him I would have liked it. I had to change it for my flying style.
