Guys, I realize that water has some disadvantages as a coolant for any
length of time. However, would it be a good idea to replace one's normal
glycol mix with distilled water prior to one's initial test flight(s) to
give a little extra margin on the cooling system? If adequate cooling is the
great unknown for first flights, then an extra bit of margin would be great
to have during that first hour cruising in one's new experimental. Replace
it with the original glycol on the ground. I have a hard time believing that
using it for an hour or two could lead to instant problems and it certainly
would be an easy little safety margin during first flight.

Just a thought, though maybe the difference is insignificant.
