RE: Arming switch - advice.
Do we have the requirement this year?
I like the idea of a device that you can remove from the plane to ensure the plane is not armed. Something that the judges and anyone else can clearly see when it is removed. It is called a battery. I can keep it out of the plane with the canopy off, and everyone will know it is safe to walk around the plane. I will put the battery in on the flight line during my startup time, when I have a caller.
I use Anderson Powerpoles for my electrical connections. They can handle the current, but I don't feel great about plugging one in the side of the plane where if it falls out I lose power. It is a failure point. I don't regularly use Dean's connectors but they do feel more secure when plugged in.
