View Full Version : P-51 Radiator setting

I manually operate the radiator and want to turn the HUD display off that so it doesnt show Throttle %, radiator position, and "enemy destroyed," by looking at the guages, is there anyway to tell what radiator setting I am at?

Unless I am doing something wrong, I seem to get the best rate of climb without overheating at Full throttle and radiator open. Of course when I get good altitude, I want to close up my radiator.

Also, for speed in a dive, is "closed/auto" just as effective as "closed?"

Thanks in advance...

There isnt really any reason to close up your radiator when you level out. You'll want to close it when you're engaged and need speed. Otherwise let the air flow.

I don't fly the 'stang often, so I don't know if it has any gauges for radiator setting, but there ought to be a lever that you pull to open and close it. If it has been animated, play with the radiator while looking aroudn the cockpit.

yeah, tried that.. no dice on the animated lever.. and in terms of closing it when I hit altitude, I like to throttle back, pitch down slightly and build speed..

I close the radiator--usually around 300+ mph with the objective of reducing drag (spelt out by one of Oleg's posts about the 51, drag and radiator settings).

I never tested the actual FB aircraft, but the Mustang was one of the few aircraft that gained speed by leaving the radiator open...the exhaust negated turbulance induced drag and created a small "thrust"....although I'm not sure if thrust is exactly what happened but I heard once that this was thought to add 20-30 mph on the aircraft...

Does anyone know for sure if the FB aircraft is faster with radiator open or closed?

i tested that one. the radiator will slow down the mustang even at a setting of 2,didt calculate total speed los but i was flying with the pit off and as soon as i opened the rad i slowed down but regardless i usually leave it at 4 at all times on all air craft unless i get in to a dog fight then i hit open or auto.

All kneel to ZoD

That was disproven...the radiator design does not add to the top speed of the fighter per say. The misconception was that it does. What apparently is the case is the radiator design is such that it has less drag than other radiator designs....so it definately has a part to play in the overall speed of a P-51 but not its maximum speed.
