Watching the sequence a second time - correction needed: looks more like a defective smoke oil valve in the left wingman and same after landing, not from brakes. Same thing briefly for the 2nd bird in trail - just in front of the camera plane. Nice job by all!
Worried a bit about the left wingman - Suspect those white puffs in his exhaust are from excess throttle movements, AND the tire smoke long after his touchdown speaks of excess braking???
