A helicopter does not descend on its own power, but can be controlled by
adjusting the ascerding force.
O Practice

throtUe stjck slowly.
. As you move the throttle up, ihe rotor accelerates its
roiating litfle by litile.

Your control, bring it back
under control by pushing
the aileron to the right. tf this

not
correct the
problem, do not give up, bul
rather bring down the

and return it to the odginal
position and facing before
tfying the practice again.
OThe earth's gravity pufls the
unit downward.
While
ascending neecls power, the
helicopter's descending is
powered by this natural
gravity.
When you want to bring the
unit down, never suddenly
bring the throttle stick a the
way down while the unit is in
the air. This-will result in a

a
helicopter
experiences the ground effect
when
its altitude
is
approximately below its rotor's
diameter
