Decided to compare all 3 planes on a climb with low airspeed max power wep.
For all 3 i started on the deck pitched up into climb, airspeed drops to which i try and hold it to a certain airspeed as best i can.
For 109 i was climbing from deck at 1.8 wep, roughly around 150-170kph never overheated got to 7K got bored. Rads on auto.
Then i took the dora out from deck same rough IAS as 109 1.8 wep with radiator fully open. Got to 6K showing no signs it was going to overheat so stopped.
Took out the mustang climbing from deck at roughly 100 - 110 mph IAS. 67" with wep rads auto. Gets hot pretty quick made it to 4K engine popped due to over heat.
Now to comparison between german and american engine cooling is huge. Is MW50 really just a magic pill?
