oh, russian quotes... i understand... but... PLS, don't make me laugh... HOW you can know more, without problems and without work?! без труда не вытащишь и рыбку из пруда, old russian saying...

plus, all this it's not light work and i how can, do this for fixes, some users here who want to know and for myself too, of course...

well, no any other ways for you to REALLY know (and try feel youself, like me and half of the world, when i search datas)...

Soviet reports from the fields were often quite exaggerated, mainly due to patriotism. And this "115 hours" is another example of this.

what you talking about? patriotism?! patriotism it's songs etc, maybe, some instructions and recommendations, but technical datas and tests it's serious science and knowledge...

maybe you mean some errors, it's can be, but again - it's all seriousness and be analyzed...

so, your words it's like "водка, матрешка и балалайка"... i sure, you not think what first sputnik and first man in space it's just JOKE and mainly patriotism too... right?

and i again can only recommend try to understand my quotes from sources...

About flight performance data, I think TsAGI reports are the most authentic.

TsAGI reports not main source, it's just science, mainly, like tests of p-47 (what is this, new features etc)... lot of important things (about control tests etc), i posted in la-7 topic...

Unfortunately no, I read it in an old magazine.

But every source states that average engine life was only 25 hours for the WW2 version. Post war improvements extended the engine life by about 10 hours.

i given you serious opinion - not from other user from here, it's author of book - about not simple situation with vk-107 and other REAL results (i and all authors not say what vk-107 not have problems, sometimes very serious, maybe was be better if author of engines finalized vk-106... but remember, Korea, yaks and very powerful p-51s... well, not simple question)...

and if you not belive, sorry, it's only your problems of faith, and for datas it's not have any attitude...

anyway, just "no way" it's not answer and not constructive...

+ need to understand, books is not internet and magazines with lot of easy edits, and have errors... and we have NEW info sometimes...

Another interesting fact:

"interesting fact" - without context and continuation, but if you not want read and understand original texts, i not really can help here...

(if shortly, i can say later some problems for serial yaks was solved and yak-9u in war can use 5 min of combat power with normal radiators settings... some problems was here, of course, ussr reality and new powerful engine - remember, pls, it's 1650 hp and remember, how long even germany have blocked 1450 hp and have problems with 1310 hp - but we just can't know all truth from original users of vk-107, needed serious works in archives AND for publics (i think, i know one book, small printing, and want buy it with wow price someday), and some strange compilations and old info it's not nice here... and IMMEDIATELY after war it's not war - different situations, no voltage of total war=more low quality, than in war, and f.e., manual for la-9 can give 5 min forsazh because for engine need to work of all time of resource=not so much accidents and more live pilots, well, it's not war... etc etc etc)...
