4 Motors in One Port?

[amrd]

I was wondering if I could use 3 Y-Splitter cables to allow one port to run 4 motors at the same time, but I’m afraid it might fry the Cortex. Is it safe to do this?

<R12> A maximum of one (1) VEX Y-cable can be used per Motor Port of the Microcontroller or Power Expander. (You cannot “Y off a Y” to have more than two (2) motors controlled by the same Motor Port.)

If you want to compete, no.

I wouldn’t do it.

Edit:
I should add IMHO it is not safe. Most typical 0.1" headers have pins rated at 3A (or less) continuous current. A 393 motor when running continuously can easily use 1A, four motors puts you over the safe limit. It will not catch fire or anything like that but there is the potential to cause damage to the cortex motor connection if operated in this way.
