the problem with a receiver pack is it will need charging after every run ,

i am totally new to 1s and 1/12th

i understnad i need 6v for the reciever/servo but what is best and safest ?

A reciever pack will only feed the reviever and servo the 1s lipo will power the speedo and motor , am i right in thinking this ???

A voltage booster just boosts the voltage from the lipo to the reciever and servo or am i wrong again (wont be the 1st time ) ??
