The end of January draws near and we're finishing the BoK development. The new functionality of the coming version 3.001 is being actively tested and debugged, our volunteer beta tester team helps us in this task greatly. This development stage is hard, but it consists of routine work mostly, not very exciting to tell about. However, there is a development which might be interesting for you to know. Andrey =AnPetrovich= Solomykin finished the Yak-7b series 36 flight model but, being the lead engineer, he couldn't just 'make a new plane'. During this work, he implemented many new features which in time may be applied to other aircraft. In addition, while we have a common flight modeling accuracy standard, this time some characteristics were modeled with higher fidelity.
