He111 water radiators

[|450|Devil]

Anyone know how to set the He111 radiator to full open?

The standard setup appears to have the radiators are in the half open position. I have bound a key to the Radiator Open control and holding the key down keeps the radiator open but this seems wrong as the radiator cocks positioned beside the pilot's right side just below the seat level are turn type and you would think that they would lock into position when turned to open, half open or closed.
