DPRC, I was reading back in this thread and I think I read something about you using a lot of expo on your controls. That normally is a pretty good thing. But you can overdo it. Especially when trying to hover. I use about 10% when practicing hovering. Anything more than that tends to hurt you when you hover. I couldn't hover much until I reduced the expo. In all other things I use 30-50% expo. Just not so much when trying to hover. Try it, I think you'll agree.
Thanks,
Barry
