I have a question about the servo power supply

the mentor comes with a 55 amp speed control and it has a built in 3 amp bec

do you think the 3 amp bec is enough to power the 4 servos

the ale servos are hs 82 small servos and rud and ele are 322 mg standard servos

their all analog servos do you think the 3 amp bec will be enough or should i run a second battery

thanks all..

the lipo battery is a 2200

More than enough ... the throws are not that much and the control surface is not that big, so load is not that high. My 5A UBEC can handle easily 5 standard digital servos.

You should be fine. But another great use for a watt meter. Make up a pair of adapter harnesses so you can install the meter between the esc's servo lead and your rx.
Power up the esc and work all your servos at the same time. You'll see if the voltage sags from the bec, and how much your servos are drawing.

And good on you for asking first.
