*'''Is the igniter a low-current igniter?''' '''''DO NOT USE LOW-CURRENT IGNITERS FOR YOUR MOTOR IGNITION.''''' I repeat. '''''DO NOT USE LOW-CURRENT IGNITERS FOR YOUR MOTOR IGNITION.''''' Low-current igniters, as their name suggest, ignite with very little current -- so little in fact that the continuity test can set them off. This means that if you do not follow this ''very important warning'', you could end up in a situation where you put your rocket on the rails, connect up the leads, go to press the button for continuity and '''''BAMMMMM''''' YOUR ROCKET GOES FLYING OFF IN FRONT OF YOUR FACE. '''''DO NOT USE LOW-CURRENT IGNITERS FOR YOUR MOTOR IGNITION''''' AKA '''NO Electric Matches'''. E-matches are ok for ejection charges in avionics bays (for L2s+), but they should '''NOT''' be used for motor ignition.

*'''Does your rocket motor have the ejection charge installed?''' This involves pouring a small amount of ejection charge into the top of your motor and putting a cap on it. Do not forget to do this. People have forgotten before (apparently) so don't let that be you, otherwise you'll find rocket will go up quickly, and then proceed to come down ''very'' quickly. And dangerously. And you won't get certified. So don't forget.

*'''Is sufficient wadding/Kevlar installed?''' Wadding, sometimes referred to as dog barf, is fire-retardant, blown-cellulose insulation (used in home insulation) that protects your rocket/shock cord/parachute protector from getting blown to smithereens by your ejection charge. The Kevlar pads in the Firestorm kits serve an equivalent purpose of protector your parachutes from getting fried. Be sure the Kevlar pad fully wraps around the area of your parachute that is facing the ejection charge. Use your head on this one -- what good is a Kevlar covering, if it isn't covering the part of your parachute that is going to get blasted with BP/Pyrodex?
