Every wing, control surface and propeller is computed separately, from the aircraft’s geometry, mass and centre of gravity. Stalls, engine torque, wind and gusts are not faked with settings: they come out of the computation.

Crashes too: an overloaded structure breaks, parts come off according to their material (foam, balsa, fibreglass or carbon), and a wreck can end up in the water.

Trainers and aerobatic planes, an FPV flying wing, a petrol-engine warbird, turbine and electric ducted-fan jets, FPV drones, and the D.E.D.A.L tiltrotor, flown by a model of its real flight controller.

Four views: from the pilot on the ground, as on a real field, chase, FPV, or from the cockpit with its head-up display, looking around.

A 5-inch freestyle quad and a 7-inch long-range quad, flown like the real thing through a Betaflight-style flight controller: acro, angle and horizon modes, airmode, and rates everyone sets to taste.

Dives along cliffs, gaps between buildings, and a race course with gates through the city.

A club field, a mountain, a canyon and an alpine cirque rebuilt from lidar surveys, a city with its river and viaduct, a walled harbour with its tides, and an aircraft carrier at sea.

A carrier under way on a swelling sea, at three scales: 1:6, 1:3 and full size. Catapult launches, approaches, landings on the arresting wires with the naval jets and their hooks, or a go-around when the approach goes wrong.
