Rad Usage
Use Oil and Coolant Rads as required to control Coolant and Oil Temp.
Use 3/4 Coolant Rad and 3/4 Oil Cooler at climb settings.
Half open is generally sufficient for most level flight except very low speeds and high boost/rpm.
At high speed 35% Radiator and Oil cooler open is generally sufficient.
Slow speed is the worse situation. Sustained slow speed high power manoeuvring with < half rads should be avoided.
