First flight after 582 OH

[924549]

I do a bunch of flying at -10 to -20c and use a 160deg thermostat in my 582. Temp hangs in at 140 to 160f without blocking the rad.

I have know a blue head 582, but before i had a gray one so without thermostat and during winter at about 30°F i succeed to have an optimal temperature of functioning with an aluminum tape stick on the radiator hiding something like 75% of the surface.
If it could help
