I want to add two low-wattage silicone heater pads on my 12 to preheat both the engine crankcase and oil tank. I will use a cell phone switch to turn on the heat a couple of hours prior to flight. Question ? does anyone know what size pad (L x W) will fit nicely on the bottom geometry of the 912 crankcase? Also, what size pad (L x W) that will partially wrap around the oil tank?

Suggestions are good.
My typical use is (1) stop for a cup of coffee, (2) arrive at hangar and plug in HPS (Hairdryer Preheat System TM ), (3) drink coffee, preflight, do small chores that you've put off, chat with hangar neighbors, (4) 45 minutes later, start engine. I would not recommend operating this system unattended.
