Known limitations

Stuff RFM can't do yet, or can only sort of do.

  • Multiplayer has had less testing than single player (see Multiplayer).
  • Flight assist tuning. Keyboard, mouse and gamepad fly through the flight assist, which works the controls like an autopilot. It holds an attitude, heading and height, and finds each aircraft's trimmed controls by itself. Its gains are in 10D Flight Assist on RFM_FlightComponent, and a new aircraft might need them tuned. Watch [RFM-ASSIST] in the debug log, it shows the target against the actual for every axis.
  • No AI pilots. You also can't place an aircraft in the air from Game Master.
  • Modded sling loads aren't counted yet. External fuel tanks attached after the aircraft spawns aren't counted in RFM's fuel either.
  • No water landings or floats.
  • Turboshaft engines only. Piston engines aren't modelled.
  • Damage only covers the main and tail rotors. Every rotor is simulated and can be shown spinning (Extra Rotor Visuals), but only the main rotor, its shaft and the tail rotor have damage zones. Engines (one zone each), the gearbox and tail drive parts can all be mapped. On other players' screens, any rotors past the main and tail follow the main rotor's speed.
  • Rotor brake is optional. Without one (the UH-1H doesn't have one), a parked rotor can windmill slowly in strong wind.
  • Fixed rotor shafts. No tilt-rotors or tilting nacelles.
  • No airspeed scheduling for surfaces. Surfaces can be linked to the pilot's controls, but not to airspeed (like the UH-60 stabilator). The CH-47's longitudinal cyclic trim is covered by the LCT schedule on the control map, and the Flight-control system can schedule its crossfeeds with airspeed.
  • Drivetrain torsion only works with one engine and lumped outputs.
  • The Mixer and Kinematics control layer (category 10) is written for a main and tail layout.
  • The native centre of mass can't move, so RFM tracks the loaded CG itself. Go by RFM's CG, not the Workbench COM gizmo.
  • Airfoil tables are only as good as their data. Made-up tables make an aircraft look calibrated when it really isn't.
