more and more I see launch controllers being build with NO continuity
the club I belong to does not have any continuity checks and launches go
just as fine if not better then launches I attend with continuity checked.
I built mine this way also and it serve me well, and I never need fear a
continuity check ignition.
I mean why run current into an igniter if you don't plan to set it off ?
Really, if the igniter you chose had continuity when you checked it outside
why check it inside the motor and run any risk ?
Also, I really would not want to have current running into my igniters or
matches at a launch continuously.
Just some food for thought.
