I'm starting to get to know my new V4 and have gotten small servos to move ok. However, when I plugged in my big Turnigy S8166M, my V4 wifi randomly disconnects from my network several seconds after I start activating the servo (just a minor test with the vertical servo movement control). Like the smaller Futaba servos I'm running (I tried just one at a time), this servo uses 6V to run.
I've plugged in four 1.5v (6v) batteries to power the EZ B. Could it be that this big servo is drawing too much power and causing the EZ B to brown out? Should I plug in a higher voltage power supply (eg. 9V or even 12v)? I read somewhere that it's not good to run the servos at higher voltages. Or should I simply power the big servo separately from the EZ B?
