Yaw waggle?

Hai-Lee

Old and Bold RC PILOT
The only time CG effects directional stability is when it is too far aft and the plane is travelling slowly.

Whilst in high speed flight there will always be a bit of "Waggle" as the air acting on the vertical fin/s is not spread down the length of a fuselage and therefore only acts on parts of the craft aft of the nominal CG point. Such "waggle" is a feature of the beast and is normally not a serious issue UNLESS you have the CG too far aft and are travelling slowly where a stall and a wing drop can be expected.

Have fun!
