The flight has one hereditary but not critical 'dislocation', a drum dog. It can be detected only in the process of operation, but our studio gives an INDEFINITE guarantee for the mechanism, the defect is quickly eliminated, a new 'dog' is made with sizes in + or - (depending on...) and the Poletovsky caliber will serve for decades. This is a 'tractor' without all the 'body kits', 2.5 days of driving are guaranteed.
