Standard Packing Blanket, with quick clamps holding front together. Reiff Pre-Heat works great. Even on cold days ( 20 degrees as example ), if you turn on the Dynon before start-up, the engine oil temp and CHT's are between 90 - 100 degrees. Starts like summer time. No warm up time. Start taxi, and beyond 122 degrees before I can get to either end of runway.
