It took me more than 4 hours total but I finally did it. My ERBE is now running with 5.5 mm bullet connectors.

Now I don't know what to do next on this ERBE. I think I covered just about everything and addressed a lot of issues. The thing is running so well now when I race or bash it. I'm out of ideas, I need to get a new RC.

How about a Losi 8ight E 2.0 buggy.
