even for a beginner i would recommend to hover (+4/5) at 3/4 stick. that makes center stick 0 full positive at 10 and limit your negative through to -4.
throttle should be at high idle at low stick (-4) about 35-40% at center (0) about 50% at hover (+4/5) and 100% at full stick.
i believe that is a pretty save setup for starting.
do not learn hovering at center stick, it is a bad "habbit"
of course like always that is my opinion and there is tons of other ways to do it.
what heli and engine do you have?
