When my son took up modelling I told him not to use an electric starter until he'd learned to hand start safely. The main reason for this was that I wanted him to get a feel for engines so he could detect any possible problems and to learn what an engine needed (prime) to start instantly. I taught him how to flick and how to follow through after the flick to have his hand safely away from the prop. When I was confident he was ready (and this only took maybe 5 or 10 minutes) then I let him connect up the glow and have a try. It started first flick (and this wasn't an .049, this was an Enya 80X) and the look on his face made it all worth while . Then I told him he could use an electric starter if he wanted to. He never did.
