about CG

 

[avbug]

About the main landing gear. CG becomes an important factor airborne and can influence the way the aircraft rotates, but on the surface and lifting off he surface, it's limited by the gear in contact with the runway.

 

[Seadogrun]

Right. Rotation has to pivot on the mains until airborn.
