My first port of call would be to isolate the factors, the first of these would be the motor. (They're full of sensors, so only one sensor needs to be damaged to send the timing out of sync.)
When you mention that you had problems with a previous ESC, it just reinforces the probability that it's the motor.
After all; ESC's usually work perfectly, or just go up in "magic" smoke.
If this doesn't work, my second guess would be the radio set-up. As this "pulsing" you mention must be from some sort of timing mis-hap or signal interference.
Failing the above... Send the ESC back to a LRP distributor.
Regards,
Julius.
