Insulation options

[AirFox]

I have a SS7 With Rotax and heater option. No extra insulation added to the build. I've crossed the Cascades at 3 degrees F. No problem keeping warm.

I agree with Scott. Your backside is no problem because you are sitting on 1-2" of foam, the seatback is 1" foam. Where you may get cold is the back of your neck due to cold air coming from the tailcone and baggage area. To eliminate this cold air source you must seal up the flaperon control horn slots in the turtledeck, and the horizontal stab trim slots in the tail access covers. One other spot for cold air ingress is the the spar ends at the butt ribs. If you make the cuffs as recommended in the manual it solves this problem, or some folks just stuff some foam into these areas. If you do these things the Kitfox SS7 stays quite warm; however I cannot speak to temps below 0F; I guess this is where heated underwear comes in.
