At the traditional tractor meeting in Burkhardtsdorf for some time a major Russian radial engine of an Antonov is always there.
Which was also filmed. Since it was very cold and damp in the morning, he made some problems but then start he ran.
Typical of old radial engines is the big smoke at startup, because a larger amount of oil goes into the lower cylinder, which is then burned.
The sound was deafening as ever.
