I was at the hangar this past week and I took pictures of our set up for preheating. For those who are interested--this is what we came up with for this winter. Our plane has an EZ heat oil pan heater which works great, except the hangar is a 40 minute drive and we don't leave it plugged in unless we are flying. The issue of having to drive out the day before was just too much of a hassle and had to be planned ahead. The hangar has no wifi but we wanted to set something up to control it remotely
