Switch for A123's
I plan on using A123's direct without a regulater. How are you guys turning on and off your RC gear? Is there a special switch harness that has a Deans style connector on the battery end and (2) radio plugs on the end that plugs into the reciever with a heavy duty switch in between?

right now I'm using a LiFePo ready made pack that has 3 power outputs.
2 rx style connectors and a deans.

right now while I test its straight into the power socket on the AR7000.

Need to come up with a switch device as well.

It was that very problem that lead me down the path to the AR7100 (and a shift to JR transmitter).
I love the idea of the power safe receiver and A123

There are some good switches over in giant scale fixed wing land (fromeco stuff and Hangtimes) but nothing heli friendly

When I initially used my a123 setup, I bought an automotive switch rated at 15 amps, and then plugged the battery into the switch, then made 3 RX outputs into the ar7000 using 1 battery port and 2 y harness in the gain port and aux port. It was a pain and a lot of wiring. I have since ditched the 7000 in favour of a 7100R and things are much simpler and the failsafe switch is nice too..

Problem is I fly Futaba so I can't use the 7100R. I plan on running a123's straight into the receiver and to the servos, but step down for gyro servo.If you not breaking it your not trying hard enough

Route I went is 'no switch'. Made a wiring harness that plugs the LiFe pack directly into the RX and used an EC3 plug as a shunt across the positive leg. Pull the plug off and it's off. Could use a Deans or whatever you have, I just happened to have an EC3 plug. No switch to worry about.

Jsenicka I was also thinking about making a unit simular to what you have done. I think I will try making my own simular to what you did here.

Which brand of LiFe pack are you using?

Thanks for your help.

Spektrum makes a heavy duty switch with two power leads in and two power leads out, I have been using it on my 700 for a couple of months now with a A123 and it is working great so far. That puts two leads into the reciever instead of only one. I just soldered the two input leads to a single heavy duty connector since my battery only has one lead.

If you plan on using a switch, you can consider a failsafe (non mechanical) switch made by Fromeco. It is called Badger switch.

http://www.fromeco.org/Products/04F...2b/Default.aspx

It is primarily used by plank pilots.

I use Deans to go from battery to Badger input/output. I have deans to two universal adapter to plug output side of Badger to two open ports on the receiver.

With Arizona regulator, the Badger's failsafe switch is built in so Deans from battery is plugged directly to Arizona's Deans in. A mechanical (open to turn on) switch is used to turn on the circuit. Arizona's power is delivered through two servo connectors on rudder and gyro gain channels.
