Paul,
Not really a good idea. Turning the heat on and off if you do not fly it
can cause condensation inside the case and accelerate corrosion. I went
from a timer on the engine heater to a temperature switch for the engine
heater.

Have you looked into the ThermoCube? It turns on when the temperature drops
below a certain threshhold. Sporty's sell it I believe.



I don't want to heat up the airplane every day if I only fly once in a
week.
