rcfreakk,

Don't make it more complicated than it is.
I assume that by box, you are referring to an RC flite box which usually has a 12V. battery for the starter and a dropping mechanism (electronic or resistor) for the glow plug. That's fine. Most CL guys use a separate booster battery for the glow plug...both work.
If the prop keeps spinning off when you start the Norvel, place a piece of thick paper between the prop and the engine thrust washer and tighten with the wrench (in case you were using a screwdriver).
