I'm sure there are tons of threads about this, but I honestly can't find them.
I just bought a used ERBE and I'm absolutely loving it, when it works. The rear drive shaft's pin keeps falling out, and I can't find a way to fix it. I've tried putting a metal pipe around it to hold it in, but when I crashed it kinda hard it just fell out anyways. Now I'm trying red loctite. What else can I try if this doesn't work?
