2. If i read your second question right, it sounds like your talking about using a servo controller to operate the esc and motor, That should work fine . the esc is just looking for a signal to make it work. or you can use your transmitter and receiver to generate a esc / motor signal. the servo controller should only see about 5 to 6 volts input no more than that, or you may burn up your esc.

Thanks for your feedback
2.) I will generate PWM on Beaglebone(of course it doesn't matter any microcontroller can be) instead of using RC transmitter. I wonder that: is there any restriction on ESCs against PWM signal that generated by microcontroller?
