Are Zippy Lipos safe with a Castle MMM Speedy?

[shaunjohnson]

if only there was a way to get this important info out to the newbies out there...
i mean...WHO in their right mind would use 18 cell nimh batts????
there need to be gearing guidelines, maby a gearing chart?
in the castle manual or castle link CD a link to brian G's gearing calculator?

BUT after hearing the above castle rep stating that the return rate is very low...that makes me very happy :D
