How many motors can a V5 brain have on competition robot if we mix the old motors with the v5 motors

[stacey_jones]

My kids are asking if they can mix the old vex motors with the v5 and it count as a lower motor count for competition. I don’t know how to ask this, but they are thinking if they mix the two types of motors they can use more.

The older motors are not legal with V5, Clever thought, but nope, not legal.

And as an FYI you can’t drive the old motors at full load

Looks like you need to get a game manual printed (https://content.vexrobotics.com/docs/vrc-tower-takeover/GameManual-20190816.pdf) and review R17 with your kids.

c. V5 Smart Motors, connected to Smart Ports, are the only motors that may be used with a V5 Robot Brain. The 3-wire ports may not be used to control motors of any kind.
