[Flightgear-devel] RFC: Control surface position damping

2007-12-02 Thread Roy Vegard Ovesen
When prssing the 5 key on the numeric keypad to reset the controls to zero, the control surfaces instantly move to their origin. Similar effects can also happen when an autopilot controller is activated, and when a noisy joystick is interfering with an autopilot controller. I think moving a

Turns out that JSBSim and YASim already has what I'm looking for. My question then is reduced to: why doesn't more FDM modellers use these features of JSBSim and YASim to create cotrol surfaces that seem to have mass? Roy Vegard Ovesen Roy: Possibly, it is because many of the aircraft
