for those making the fireball shooter, keep reading at the end for a little bit of inside glow plug information.
Step 1: First things first
i am not redoing Kipkay's instructable, but merely taking the open-source horse by the reigns and going to town. i've got a quick upgrade and some information that might help with glow plugs. hope you enjoy.
now go get this stuff:
some stiff bus wire (around 22g)
some hookup wire (whatever gauge you want)
a small bolt slightly smaller than your glow plug's lead
heat shrink tubing
Step 2: Wind your coil
if you are making a lead wire for your rc car, continue the coil until you have about a 3/4" coil.
Step 3: Cut the cord
for an rc car lead wire, just snip the coil at both ends in the same fashion. make sure you remove the screw before you snip the wires. skip step 4
