do I need to add a BEC if I add a second servo?

[5wattchamp]

I have been thinking of adding 4ws to my AX10 (it's used just for bashing) I'm running a Novak crawler combo, hitec HS 645MG on the front and a 3PM futaba. Will I need to add a BEC if I add a 2nd servo(HS645MG)?

i run 2 hitec servos 1 being a 645 and the other for my dig (full size) just fine

You really only need to run a bec when you up your voltage from 7.2 volts. The bec in your receiver doesn't like the extra voltage and causes problems with a drop in voltage to the servos.

it will work without one.but the servos will be much stronger with it. the bec will give the servos all the amps.,and volts they want.

Novak's ESCs have very robust internal BEC ratings. I believe it's 5 amps, and that will handle dual high torque servos, no sweat. I ran a super sized crawler with dual steering and it was never a problem.
