Hi,I need to control 24 servos with a Mini Maestro 24-Channel USB Servo Controller and in order to power the servos I am planning to use a 8-15A UBEC with a 1100mAh 11.1V 20C lipo Will it be enough to control the servos? I am using MG996R Metal Gear Digital servos.And If I use a pair of wixels to controll them via Mini Maestro 24-Channel USB Servo Controller will I be able to control the servos by just sliding the bars?
Hello. How many servos are you going to use? I am not familiar with that particular model of servo, but a good rule of thumb is that you will need a power supply that can supply at least one amp per servo that it is powering. If your UBEC outputs an appropriate voltage and can supply 8A then it should be good for powering 8 servos. If you need to power a lot of servos, you can cut some traces on the Maestro so that different groups of servos are powered by different UBECs.
I have to controll 24 servos http://www.aliexpress.com/store/product/MG996-MG996R-Metal-Gear-Digital-high-speed-Rc-Torque-Servo-For-Helicopter-Airplane-CAR-Boat/614241_640843667.html so instead of using 2-3 ubec if I use a 25Amp ESC like http://www.rcdhamaka.com/index.php?main_page=product_info&cPath=100_95&products_id=312 will it be enough to controll the srevos?If not which will be perfect for the job.
An ESC is different from a BEC. The ESC you linked to has a BEC in it, but it can only provide 2 A, so it would not work. Does this make sense?
If your servos can tolerate being directly connected to the voltage of a fully-charged two-cell lipo pack, you could just directly power the servos from a two-cell lipo pack and forget about the BEC(s).
