One of the downsides of the 12 in cooler weather is trying to keep the oil temps in the 185 to 205 range they prefer. Some put put duct tape over their cooler, others get creative like John Bender and put in a quality thermostat. John lives in Iowa and I don't think the outside air temp has reached zero since November. But John still flies because he bought a Reiff preheater and a ThermoStasis thermostat and has sold the rest of us on its reliability. He had several threads on here about it. Anyway....the price was $89. Like Vans they have announced a price increase in two weeks to $119. If you were holding off till next winter you may want to re-think it. I did. So did Larry.
