The coming LEGO City sets for early 2020 aren’t that exciting overall, but a couple of the upcoming sets feature real flying LEGO builds!
Fire Response Helicopter (60248) and Police Helicopter Transporter (60244) both feature the tried and true “zipcord” method of making the helicopters fly. You insert the toothed plastic pull, then PULL and the teeth mesh with gears to spin the helicopter blades lifting the set away from the launcher.
To start the year, there are 6 new police sets and 1 small fire department set. Crime continues unabated while arson is down, I guess.
