Not to let a little cool weather stop me, I went for a one hour flight yesterday. Temps on the ground were about -8F (-22C), and at 6500' were -15F (-26C). I have spent a fair amount of time weatherproofing my plane, and messing with heater arrangements also. Cockpit temps were probably in the 50F range, so really not too bad. I have one more heater modification planned, which should bring the temp in the cockpit up to summertime temps. I have one 2" scat, 9" long Robbins heater on the right tailpipe, fed with restriction from behind the #3 cylinder. The other heater is a 1.5" scat, 9" long Robbins on the forward crossover, fed with restriction from the left cooling inlet ramp. My last modification will be to put another 1.5" heater in series on the other crossover pipe.
For those who haven't done a max angle, sustained climb in these temps, it is breathtaking.
Something else I've noticed over the years in very cold flying is the flap motor sounds. It makes some real clunking/clattering sound. I mention this just so that if any of you experience this, it appears to be normal. I'm sure it is related to the grease viscosity.
