Are Zippy Lipos safe with a Castle MMM Speedy?

This is all great stuff... somewhat dis-heartening, but good stuff. I would consider myself a newbie, with SOME experience. I purchased an E-Firestorm and dropped in a Castle 5700 (with NIMH), followed that with a nitro PE, then an E-Revo (stock), then an 18R and added the brushless and a LIPO... THEN, bought the big boy (for me), the CC MM Combo for the E-Revo. Having the Firestorm and the 18R as brushless, yes, they prepare you some what for the bigger truck, but there is no way I would have had the desire (and possibly the need to) view a forum or a thread such as this. It wouldn't have been relevant. The cars and motors on the smaller stuff is much more "disposable" if that is fair. As stated above, now that there is a grand into this car... I'm going to make damn sure I'm doing some research. There should be a huge disclaimer that, a. you need to know what your doing, and b. you need to know what your doing. I have Zippy's with all stock gearing (19/68) and I'm increadibly concerned that my batteries may now kill my ESC. From the sound of this thread, if that happens, that's just too bad for me. If you read the misc threads found here and on other forums (tx), numerous people are geared up much higher than I am... and promoting it. If you are a newbie and reading and trusting these forums, you're destine to destroy these parts.

My two cents.

I do appreciate the knowledge in this forum as well as the responses from Castle and those users that have the experience and the electrical knowledge to back it up.
