Top speed Bf109G6 late vs La5FN @7000m

Note that it is very common for the SAME aircraft to be vulnerable to overheating related engine failure at low speed/altitude AND also be vulnerable overcooling related engine failure at high speed/altitude.

Amogst US aircraft, the P47 had overcooling issues at altitude and so did the p38. The p38 suffered such severe overcooling at high atitude in the ETO it caused turbocharger failure. Amusingly this has led to a rather curious myth amongst the less informed that the P38 was withdrawn form ETO operations because the PILOT got too cold due to poor cockpit heating. The plane suffered mechanical issues due to overcooling.

As far as the LA5fn goes it had severe overheat problems early in development but I had the impression as time went on it developed an overcooling issue instead. So not all LA5fn were the same.

la5 does not overheat at all at altitude in game. comparing with that, i am really suprised that you said 109's overheat model is a joke. this makes it can beat 109easliy up to 10000m. does it make sense according to history record?

Forsazh in the La-5, La-5F, La-5FN or La-7 does not work in 2nd charger gear. This is modelled by the game internally, you can also see it in il-2 compare as in 1st gear it gains 30+ km/h with 110%, in second only about 5 km/h. The only reason it gains something at all is that flying with 110% also increases engine rpm a little bit over the 100% setting (most noticeable effect above FTH of 2nd gear).

So when you're flying the La at 110% at altitude, you're actually only flying it at 100%. It overheats about as much as a Bf 109 at 100%.

Thank you for the explanation, JtD
I am not sure if no overheat at all with 100% thottle and Rad closed could really happen on La5 in real life. but my speculation is that such advantage of la5 at altittude will get bigger in the new patch 4.11 with new overheat model introduced.

Engine rpm is VERY important for overheat in 4.11, and you'll hardly be able to run around with 100% prop pitch in any plane, even if you considerably cut down on power. The La should be no exception.

Doesn't really matter with 4.11 coming out this morning as its all changed.

However I am not sure what the problerm is with the 109G6 under the old patches. You get several minutes before overheat warning and then 5 or 6 more minutes with overheat flashing before any damage is done. Basically you can fly the G6 for almost 10 minutes before any damage occurs. 10 minutes is a long time online.

If after almost 10 minutes of combat you need more time then you dive, open the rads, cut throttle and let the overheat warning go out (takes maybe 10 seconds) and then you get another 5 or 6 minutes of full throttle.

Overheat is only a problem in the G6 if you panic like a big girls blouse the instant the warning flashes up.
