Verticalmotionincludesrisingorfallingvertically.Asthetextmentionedpreviously,thequadcoptercankeepbalancehorizontallyby
fourmotorsmaintainingthesamerotationrate.Asyoucanseefrompicture2.2.1,ifthefourmotorsincreasetothesamespeed,the
generatedthrustwillbelargeenoughtoovercomethequadcopterweightandrise,andviceversa.Undertheconditionofno
surroundinginterruption,thefourmotorscangenerateenoughthrusttoovercometheweightandtherefore,thequadcoptercan
suspendintheair.
Thequadcoptercanflysteadilyintheverticaldirectionaslongasthefourmotorsmaintainthesamespeed.
