Excellent!

 

"1st Border Altitude", and "2nd Border Altitude"?  What altitudes are these at?

 

 

Technical data

Engine: 12-cylinder liquid cooled M-105PF engine
Power output:
1210 b.h.p. at SL
1260 b.h.p. at 1st border altitude
1180 b.h.p. at 2nd border altitude
Gear reduction ratio - 0.665
Dry weight - 620 kg

 

 

Also didn't realize the Yak-1 shared such a similar weight to the early Yak-9s, interesting!

To me, when I look at Yak-1b and Yak-1 and Yak-9 and Yak-9T, there is something which simply does not make sense to me. See:

My impression is that the Yak-1b and Yak-9T are simply "older" flight models then the more recently added Yak-1 and Yak-9. Do you have any word on that?
