Does anyone know what the best cruise engine RPM on a 455 would be? Where performance and fuel efficiency would meet on a graft. Basically on a standard day, with no wind, on flat land, at sea level. It seems to me I’ve heard 2700 RPM’s might be the number. Or would a vacuum gauge be the better indication?
Thanks, Scott.
