Hey guys,
currently i am making custom 1/5 rc truck (still in drawings) but i need advice for the electronics.
The things are:
1. i will use 2 brushless motors with 2 ESC`s. I want to use a single lipo pack (shorty) just for the servo. The servo is HITEC D-980TW 32-Bit, Monster Torque and i will use it at 7.4 v. Now the problem ... i wanted to use it with the new traxxas receiver but i think it`s impposible becouse i will put a BEC but the receiver can`t handle more than 6v. What are my options? Maybe i need some HV receivers like Futabas?

Hello!
I have a question regarding electric current between components ESC, receiver and servo motor. For example: I have on my ESC BEC output: 6V/2A (switch mode built-in), my receiver operating voltage is 4.8 - 7.4V and servo motor Stall current (at locked) is 5000 mA @ 6.0V, so I am interesting how effect on servo motor at locked condition the loss of current because from technical specification is clear that I can deliver through my ESC only 2A and not 5A like is written in technical specification current consumption of servo motor. Do I need some extra external bec on my receiver?
Thank you.

If your going to be using amp hungry servo, use a stand alone BEC.
When I raced short course, I always used a castle BEC because it eliminated any worry of brown outs, or glitches. Its cheap insurance for how low the cost is.
