I know the LA irritates some folks but please humor me. Just looking for opinions.

All things being equal who wins the Yak or the LA.

La-7 because of the slots

La 7 is faster (up to 10K) at WEP, has better climb rate, much better acceleration, a huge advantage in guns lethality and actually even turns better than the yak-9u (Some people may not believe this, but most LA-7 pilots you encounter seem to fly with a constant firewalled throttle

).

So all thing being equal, the La wins. But things are almost never being equal though...

Are you saying it will turn better if you cut back on the throttle.

Is this is serious question?

Yak 9u can only win between 13k and 16k where the La7 has a serious dip in power causing its acceleration and sustained turning to dip somewhat.

So if you are in a Yak9U stay just above or just below the cloud line.

I like the Yak9U and La7, although i usually fly the Yak since the inline engine makes it look nice.

Uh..La5FN can out-turn a La7 right?

That is the claim..........though it makes no sense, the LA-7 is the lighter of the two, I think it is because the LA-7 is faster and people don't use the throttle right, at equal speeds the LA-7 should turn the same as the 5 at the very least.

okay, thanks, do you have any advice on throttle management though?

Nimrod45 · « **Reply #10 on:** July 23, 2007, 12:01:11 PM »

Sorry, no I don't, but I am going to find out through trial and error, Lusche probably knows I think he is a fan of the LA-7.

PanzerIV · « **Reply #11 on:** July 23, 2007, 12:04:47 PM »

okay, cool, maybe if the La7 engine RPM and Manifold pressure was put at the RPM and MP the La5s engine works.
Wonder if Sodas says anything about this.

PanzerIV · « **Reply #12 on:** July 23, 2007, 12:08:20 PM »

usually the La7 turns good enough for me, i just wasn't sure if La5 or La7 could turn better, i guess since La7 has more power and has been lightened its turn radius should be better.

La7 is slightly lighter than the La5 and has 220 more Horsepower provided by its engine, its got more guns but the B20 cannons are lighter than the ShVAK cannons.
The LA7 seems to have a slightly shorter fuselage than the La5, only about 3 inches.

Oh yeah, i was on the internet once and found a La7 manual, Ill send the link to anybody who can read in Russian! lol

Third thread dealing with the Yak-9U.

we have the La5FN and its engine is identical to the La7's.

Other than a slightly different prop the net thrust at the prop is the same for both.

La7 gains on weight and drag (and cooling)
