Armox is on the same level of unknown as HW brushless drive: some people have tried it and the results have been mixed.

I'm not trying to pick a fight either, I just thought you'd like to know that current experiences with certain materials are not what you'd expect, or the same as they used to behave in the past. With Robot Wars back, there is going to be a new arms race, and its going to be fun finding out the results one way or another.
