Yes, you just plug the glower on for a few seconds, pull the pullstart and then you basically can remowe the glower immediately, or when the engine has been running for a few seconds. A glower is a glover so to say

There is a switch on the radio, and sometimes on the car, but i prefer to just use the battery directly on the receiver.

The radio receiver in the car requires power, and it is also powering the servos.

A starterbox is more or less universal (may vary some in strength for larger or smaller engines) not all cars have the flywheel through the chassie plate, meaning that you can't use a starterbox on them

Do you mean battery packs instead of several AA-batteries?
