I started the day at the airport cooking breakfast for an astounding number of people considering the weather.
After that, I made a start on installing the turbo inlet tube on the plane, then went home so we could take Tilly to see Santa.
In the evening, I installed a new LiFePo4 battery in the van. I used to have 4 UB12220 wheelchair batteries that are rated at 22Ah each, so 88Ah, of which about half is usable before you start damaging the plates. They weigh about 15lbs each. The new battery is 50Ah, of which pretty much all of it is usable, and it weighs about 19lbs. Progress :o)
