That's not what I meant. In the condition that you have to choose between either neck or tail(like the comic) I'll choose neck. I know that in reality

A snake has a little bit of neck, but most of its body is its torso, up until its scoots (aka its butt and cloaca) where it then transitions into tail.
Do you plan to buy the motor or make one yourself? If you do make your own propellant, I'd recommend you build a "grenade box", basically its a wooden box filled with dry hay which absorbs moisture to maintain the propellant's potency over time.
I'm still a little while away from using engines like that anyways, I'm working towards my L1 currently, so I won't be able to use motors like that for a while.
