I've been noticing my heli feels pretty mushy and kinda unresponsive hovering, I've been feeding out the expo because I think it's just that I don't like the feel of it at all. When talking to one of the local heli pilots at our shop he told me he can't fly helis with expo at all. Might just be that.

But yeah if it's a question that could potentially lead to a crash it's probably best to have someone that really knows helis look at it in person.
