Are Zippy Lipos safe with a Castle MMM Speedy?

No I mean the e-revo post refers to a 4s set up using the MMM set up, what I meant was the VXL Manuals saying gear up from 2s to 3s (same principle which contradicts what is said here re - gearing down on more volts to lower temps)

example:



But I know a lot of people run a VXL on stock gearing with 3s and it's fine.

What we are being told here on the Savage Flux is essentially the 20t Flux pinion is for 4s, we MUST run the 25t pinion on 6s otherwise it could blow the ESC, it's happened on a Maxcramps pack http://www.ausrc.com/forum/showthread.php?t=15868 and apparantly on a Zippy as well http://www.rctech.net/forum/electric...os-smoked.html . (Could just be a faulty component but in the case of the Flux blowing they are pointing the finger at people running the 20t pinion and not the 25t)

Now doesn't that sort of contradict the whole premise of gear down, volt up = cooler system???
