I seen a couple of posts that were terminated due to asking questions about products from banned manufactures. My question is: Is there a list somewhere of these banned manufactures, and if not; is there some way someone could list them? As a general rule, I usually stick with OEM parts with my various hobbies. Sometimes however, I do go with after market products if I find that an OEM part is having repeated characteristic problems.

I haven't run into anything like that with my Spartan or E-Max though, that Traxxas didn't offer an upgraded part for (or that I couldn't come up with something myself); but if I ever due, I would like to know what companies I should consider staying away from.
