Dual (sensorless) brushless motors on a single ESC?

I'm thinking of putting two milder (Hacker C40) sensorless brushless motors on a single ESC, in this case a JETI Master Car Sport.

I'm only going to be running 6 cells on this, and the vehicle in question is going to be a mostly stock Clod Buster.

Just wondering if this is going to be a bad idea. The MCS on paper and in measurement seems to be able to handle the extra current draw without any problems... but i don't know how two C40s are going to affect it.

My other truck (a 6WD Clod) has three MCS controllers, but each plugged into a single C50 motor. The C50 does drain quite a bit more power than the C40, but i figured i should ask and see what anyone else has to say about this.

My other worry is that a single battery will not be able to keep enough current fed into the two motors to keep them happy. A single C40 running on a touring car i measured out to give about 14A under very light load.

Thoughts?
Thanks in advance!

yeah it can be done, but its not very easy. you have to put both motors in the exct same position, and keep them that way the whole time. i not sure that one pack can handle 2 c40's, especially on hard acceleration.

Basically it can be done, but chances are it wont be worth it, your better off buying two escs and hooking them up with a y harness.

It can't be done on a clod buster. If I remember, the front and rear drivetrain are independent of each other so it is impossible to keep the front and rear motor in perfect sync with each other all the time.
