Much left to be done for realistic behavior:
- wheel friction on crosswind - totally unrealistic at the moment, airplane weathervanes too much and requires way too much rudder when on the ground
- turbulence behavior and upward/downward drafts and currents
- adverse yaw effect
- turboprop drag
- p-factor and slipstream
- Inertia. Responsive like an RC plane. Rotates too easily around CG.
- Ground effect. Still a bit tweaking needed.
- Wake turbulence !!! - allow us to feel the impact ( and danger!) of entering AI / Multi-player aircraft wake streams
