Are Zippy Lipos safe with a Castle MMM Speedy?

Sadly, I know of several myself that would go out and drop 1K on something that will impress their friends. They dont look at it as something that they need to learn and understand - its simply the biggest, baddest, fastest thing the drone behind the counter sells. The same sales guy that sells a rustler to a kid while telling him that "yeah it will run fine in grass" will also sell one of these with no questions asked.

I know quite a few RC'ers that have never looked at information online for the hobby. They rely completely on what their LHS tells them. When I ask them questions, they get that same blank look that my LHS guys give me when I ask them about certain products we here know in depth.

Linc, I think you may be on to something with your idea on the "tuning" instructions. Knowledge is power.

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.

Yep. You have that right big guy!

I can safely say that there are not many inexpensive 4s lipos that can run a monster combo... Unless you plan to parallel a pair of 4s 3000+mah 20c lipos...

5s and lower gearing is a much better choice for the 2200 motor, as it opens up some pack choices. 6s I am not so sure about. Spins the motor a bit faster than I like, but I guess it is ok. With 6s and lower gearing I am sure a pair of 5000mah 20-25c 3s lipos wil do fine.

Was that a sales pitch?!?!?! I REALLY like the idea of 5S also - which is also a down fall of these new trucks - so far, one is limited to either 2x2S or 2x3S. I'm thinking 5S saddle style packs.......
