Yes, but..........

You need to stay within the "turn limits" for the ESC and you need other bits if you want a dig in the rig.

A single ESC feeding a servo dig/Punk dig can feed 2 motors and give front/rear dig. You also need to see if your 3+ channel supports this.

by turn limits you mean if the esc only supports a 7 turn motor and i want to run 2 13.5 turn motors it wont or what! Im a lil confused! and also im running it on a t-maxx that i converted over to electric! so its only running the motors and the steering servo!

Sorta, the turn limits are not really linear.
What I mean is, if the ESC has a single motor 12T limit you will still likely have issues if you run 2 24T motors.
The issue is mostly you overload the FET's (power bits in the ESC) and they, "Let out the magic smoke" and it quits working. It will run those motors, the big question is for how long.

yes you can run 2 motors but if its rated to a 7t you should be fine with 2 14t+ motors. i know the sidewinder v2 and sct can handle more than the sidewinder v1 but it was only rated to 19t brushed so i wouldnt try anything lower than say 2 20t motors on it and check the temp

are you talking about running two brushless motors off one ESC or two brushed? i wouldn't attempt to run two brushless motors off one ESC. if you are going to run two brushed motors off one ESC on an MOA rig, just be prepared for clod stall.

It looks like you're talking brushless motors here, and from what I know, it won't work, even if you go the highest turn, lowest amp draw possible motors.
The ESC needs to receive feedback from the brushless motor, be it back voltage on a sensorless motor or rotor position from a sensored motor in order to know that it is firing correctly and that the motor isn't stalled.
If you try brushless motors, I think in the end you will end up with two destroyed motors and one destroyed esc.
