* Spin - Spins are caused loss of stability in the Yaw Moment axis. A stock [[Aeromatic]] [[FDM]] yaw section does not take alpha into account when calculating the yaw moment. | * Spin - Spins are caused loss of stability in the Yaw Moment axis.

* Faking lift polars - If we assume a symmetrical airfoil that stalls at +/- 15 degrees (0.26 radians) AoA and assume the lift is linear between the two we can create a table like: | |||
<table > | |||
<independentVar lookup="row">aero/alpha-rad</independentVar> | |||
<tableData> | |||
0.26 0.26 | |||
-0.26 -0.26 | |||
