Interesting to see the Mig video as I follow Randy W Ball who operates one privately doing air shows around the US. First saw him at San Marcos and then at a smaller show in Lancaster PA. They recently had to change the engine and detailed the work on FB. In the US lower limits operate at shows!
He’s actually very professional and knowledgable. His FB shows in great detail the engineering work carried out. He even does his display at night sometimes.I'd say that blokes a NUTTER
