Q: What determines the earning power of premium vehicles? If you take the Soviet P-40E and P-39K, the difference is huge, and you can also include the I-16 type 28 and the I-153P. The BR of these aircraft is virtually identical, but the returns vary considerably.

A: The economic level and effectiveness of the specific vehicle. There is an error in the economic level of the I-16 and the I-153, we'll fix it. I-16's reward will be a little smaller, but on the other hand its cost of repair and crew training will be lower as well, while the situation with the I-153 is the opposite. Thank you for pointing it out! Do not hesitate to submit such errors on our forum in bug report section!
