Design and development

The Sycamore features a single main rotor, a two-seats-in-tandem open or optionally enclosed cockpit, tricycle landing gear with wheel pants and a four-cylinder, liquid and air-cooled, four-stroke, dual-ignition turbocharged 115 hp (86 kW) Rotax 914F engine in pusher configuration. The 160 hp (119 kW) Subaru EJ22 is optional.[1][2]

The aircraft fuselage is made from bolted-together aluminum tubing and mounts a 9.10 m (29.9 ft) diameter Advanced Kinetics rotor. The tailplane features five vertical tail surfaces for improved directional stability. The enclosed Sycamore Mk 1 version has an empty weight of 380 kg (840 lb) and a gross weight of 590 kg (1,300 lb), giving a useful load of 210 kg (460 lb).[1][2]

gollark: Neural networks basically *are* just something like human intuition running on computers anyway.
gollark: Or practical.
gollark: I don't disagree. I just think emulating human emotions in existing ML stuff wouldn't be very useful or good.
gollark: Human emotions are *very specific* layers of abstraction.
gollark: Also, we can't really.
