Contact,
I agree most of the time. My point in sharing the video was to be ready.
On this morning, which is very rare for most of my trips down the river, the air was cold and dead calm.
I had flown for 15 miles at 100' AGL or less without a hand on the yoke. Another Maule and I were headed to a friends house for coffee and breakfast over on open fire, and I was following along 50' or so above him and 1/2 mile back. When I get a chance to fly hands off in the Maule, I am definitely going to take it.
As I rounded the point of the hill, I decided to drop down closer to the river. That is when I caught the prop wash, prop rotor, wake turbulence, or whatever you want to call it. It was sudden and damned sure surprising, but I didn't feel out of control at anytime. A bit of power and some control inputs kept the plane straight and level. As you can see in the video, I was out of it as quick as I was in it.
I had picked up some turbulence following friends down the river before, but normally at a fair distance below the level of the lead plane. I suspect, being a redneck from West Texas, that it was the cold air that had kept the rotor higher and basically straight behind the Maule.
Anyway, the coffee was strong and hot, and thick cut fried bacon and eggs over an open Mesquite fire is hard to beat.
