Physics doesn't care... It's not a kevlar or carbon fiber wrapped rotor, so I still say it'll crap out.

It may not do it immediately, but the forces are that much greater when you spin it a little under twice what it normally spins in the VXL setup (35k RPM vs. 65k RPM).

It becomes a question of "how much sooner" as opposed to "if". You can take the chance if you want though. Gotta post pictures once it does go kablooey though....hehehe.
