Sounds like the esc is needing to be upgraded to a unity or similar. Might as well do motors too.

This is what happens if theyāre not crossed
Have you checked the motors on the side that works just one at a time to make sure that one of the motors isnāt bad

Didnāt really get it 
You mean, does the motor spins by itself when itās connected?

I was just testing and realized that Iāve plugged in the halls connector of inactive motor and the one connected to phase is spinning fine
Is it possible that the hall connector is damaged? (The wire) and because of that we have what we have?

I fell asleep. Thats weird. Hook up the motors with no hall sensor. Just the 3 phase wires.
Blue/blue red/green black/yellow
Oh wow, seems to be working just fine!
So I suppose the hall sensor connectors are broken?
Most likely.
But hook the phase wires up like I said and put the sensor wires on and see what happens
Well is it still working?
Sorry, I was asleep! The last video is what happens if I do that
I blame the hall sensors, so I need to repair them and see what happens then
I wouldnāt even mess with trying to repair the halls. Iād run it.
Iāve enclosed my Losi XXX chassis in a prop as a drive-able robot using an Arduino for control. When I try to accelerate forward the motor just whines and the car doesnāt move unless I nudge it with my foot. Once itās moving it drives just fine but Iām having trouble diagnosing why it wonāt take off.
Someone suggested the weight of the enclosure on the car (4lbs maybe) and that I might need torque-ier gearing. I havenāt yet calibrated the ESC but thatās the first thing Iām doing when I get home from work.
Wondering what the motor whining means and what else I might think of to fix this?

Mine? No, bearing seems fine
