I had the Reiff oil sump heater installed back in August. Last time
I went flying was 2 weeks ago. Put the 2 car blankets (those blue
quilted things from your favorite Big Box hardware store) over the
cowl after flying, made sure the heater was plugged in, patted the
putt-putt on the spinner and went home.

Call me a sucker for marketing, but what covering the prop and spinner?
The point that the prop and spinner hanging out in the cold will transmit
that lower temperature through the crankshaft deep into the engine seemed
logical to me.

This is why I broke down and bought the insulated cowling cover and
prop/spinner covers from Kennon.

After three days of being plugged in and covered on a sub-zero day, my
aircraft's prop and spinner are still warm to touch.

I live in the 'burbs of Denver.

Say hello to my brother for me. He lives in Firestone.
