I don't know of a way to check static or downline rpm's on a V4. I have to assume it's about half of mid-stick, which is about 3,000-3,200/2 = 1,500-1,600? I understand that braking, regardless of stick position, is immediate. If I slowly reduce power, there is negligible prop noise. I may have to raise my normal flight condition rpm's.
Thanks Peter.
