If you maximize angle of attitude at rest on the ground, I'm guessing you're doing so by use of shorter main gear. Doing so reduces your useable angle of attack on the ground by not allowing as much rotation of the fuselage during take off and landing. Put it up level and put a skid on where the tailwheel would mount - my skid is square tubing filled with lead to help CG. This should probably be in a different thread.
We are all spoiled this year, I haven't even seen 40 below yet (though I haven't paid close attention on the coldest days) let alone the real cold. When I used to fly the open-air Trike on skis, I used one of those car seat heaters, about 5 amps.
