The undercarriage legs are appropriate for this version, which is one more nice thing.
I cannot justify buying yet another Yak-1, but I'll follow this company with interest.
Now that's interesting - looking at the appropriate sprue image, I see two different styles of legs, one style having the bottom section more squared-off than the other. According to the instruction sheet image, this is the correct one for the Yak-1b. The reason I mention it is because the Amodel 1/72 Yak-1 includes both types as well, but, if I remember correctly, the Amodel instructions tell you to use the square bottom section if the model will be fitted with skis. I've looked at photos of Yak-1 aircraft with skis, and those aircraft had the
rounded bottom section, the same as Yak-1 aircraft fitted with wheels, so the instruction (again, IIRC) is incorrect. So, in effect, the Amodel Yak-1 actually includes optional Yak-1b landing gear parts. Thank you for helping me to understand this!
