It's a switching voltage regulator, kill switch, and noise filter all in one. What do you guys think. I am not sure if I am understanding this redundancy thing because in the event of a receiver pack failure, I would certainly want my ignition pack to fail with it

Do you think it would be adequate noise filtering?
