R.I.P.
Y'all know about prop braking. One thing I learned with my present U/L is the effect of the resulting negative prop wash. It's only noticeable if you idle the engine real slow, like I have to because I don't have brakes. The effect is more pronounced with large and low pitched props.
I noticed my tail has less control authority at idle because of the slowed air behind the prop. On a tractor engined U/L it even affects wing lift and stall speed at idle. With a big enough prop, the air is slowed for a significant percentage of the wing span.
It is most noticeable when landing in bumpy afternoon turbulence. I can control the plane more crisply in strong turbulence near stall speed if I crack the throttle.
I'm posting this in The Light Stuff forum because the effect is insignificant on faster planes that have smaller props with more pitch and brakes.
