Powerbox help needed please.

[jon84uk]

Hi all. I am currently building a extreme flight 78". I am using a AXI 5330/24 motor with a castle phoenix edge HV 120 esc, 2x 4500 5s batteries.

I'm completely confused about what power box to use and or what batteries "1 or 2" are needed.
I'm using 5 Hitec HS-7955 TG servo's so will need a built in regulator in less I use a cc bec.
the two I've been looking at are the:

powerbox evolution http://www.motorsandrotors.co/index.php?main_page=product_info&products_id=159
redwing power box yellow/red. http://www.bigplanes.nl/contents/en-uk/d76.html

So my question is, which one and what batteries do I need, and as they say nothing about electric setups only talk about CDI's so can I use them or do I need a simple battery backer safety switch.

last part of my build so help would be greatly appreciated.

No need for all that. I run the CC bec pro and a 7 chanel receiver. The extra power lead is on a Y harness on the rudder servo. Since I have HV servos I could just use 2s lipo as my receiver is good to 10v.

I run 12S on a Motrolfly 4330-206 with the CC HV 80. Batteries are either Glacier 3700 or Revo 4.35 blend 4600 (weight is very close and I need the weight in the nose).

hey thanks for the reply. I'm using a http://www.graupner.de/en/products/65b0c353-27dd-41aa-8f7c-6f8d6276fd3d/33516/product.aspx. I cant see anywhere that's shows it's operating volts.

So how exactly does it all connect together to use two backer batteries, or separate receiver, servo batteries.

I've looked for hours and hours and there is nothing out there to help. my local shop know nothing about it either lol.

Don't rightly know. Mine looks like this. I tapped in to the low side of the 12S harness (black wire in ESC red wire on jumper). Two power leads to the Rx.

You do not need a BEC or regulator for the 7955 servos. The HS-7955TG servos are the only servos we have extensively tested here at Hitec and found they can handle the direct voltages of a HV 2s lipo/liion setup without issues.
