Subject: [FlyRotary] Re: coolant/water percentage?
I'm planning on running this stuff (water with conditioner) during times
when freezing level is up above
10 or 12 thousand feet (it's 15K here in Texas in summer), then swap out
to
50/50 when cooler OAT and therefore don't need "optimum" cooling.

Why do you care what the temp is at 10-12k feet? Do you think your
thermostat will ever close completely at cruise power for long enough to
freeze water in your radiator? Unless you're planning to completely shut
down an evap core in cruise, I don't think you will ever need to worry
about
freezing in flight.
Cheers,
Rusty
Rusty, #2 reply - reason I'd even fly at 12,000: Flying westbound, if I
have winds from 240/40 at 2000 to 4000' and above, I sometimes fly at 100'
AGL (or somewhere below 500' so I'm in the "170/10 sfc winds". Going east,
I fly at 12,500 for the strong tailwinds.
