The Power Pole connectors are really nice and can handle a lot of amps. I use them on my stuff. However, most people seem to leave the connector ends unsupported inside the plane and Power Poles don't like that. They can be shaken apart in that enviornment, causing an ignition cut. The easy way is with something that you already have versus what you have to go out and buy. Power Pole connectors are not standard hobby shop or small electrical store items.

There are a lot of ways to do your ignition wire ends, you just have to pick one.
