Default AR7100 in Electric Heli?

Does anyone know how to connect the ESC to a spektrum AR7100?

I'm new to electrics, but from my understanding, the battery is connected to the esc with is then connected to the rx right? But the AR7100 has a dedicated battery line, so where do you connect the esc? are you supposed to separate the voltage lines from the throttle line on the ESC and connect the voltage lines to the dedicated battery line on the RX, and then plug the now single throttle line to the throttle port?

I'm a noob, so any input pointing me in the right direction is very much appreciated = )<br type="_moz" />

I guess the AR6100 and AR7100 is build very similar. If so, you can just put the ESC-cabel into the Trottle connector at the AR7100. The AR6100 does also have at Batt connector, but you don't need to use it if you'r powering the receiver by the ESC.

All recievers have whats called a power bus. That means that all of the ground pins are connected to a common ground, and all of the power pins are connected. You can put in power on any connection, including the battery or any open servo port.

In the case with electrics you plug into the throttle channel and that will power the rest of the system.

so it is possible to power a BEC with the ar7100 instead of spicing into the power leads? or have i misunderstood the ar7100?

The RX doesn't power the BEC, the BEC powers the RX. Take an align ESC with built in BEC for example. All you do is plug the ESC into the throttle channel of the RX and it will also provide the power to the RX. No other power is needed and the power slot of the RX can be left open, nothing needs to be "spliced".

If you have a separate BEC, just plug it into the power slot of the RX. If your ESC also has a BEC, when using it with an external BEC you should remove the power lead from the throttle channel connector of the ESC and secure it. You only want one BEC supplying the RX, not both. The other end of the external BEC will have to be spliced into the battery connector with the ESC.

the ar7100 has a power slot in it as i understand it. can this power slot be used to power an external BEC instead of soldering the BECwires into the EC3 that the battery plugs into to.

maybe my question is not understandable, so i rephrased it.

The idea of powering a BEC with the RX makes no sense. The point of a BEC is to power the RX with 6V by reducing the voltage from the main LIPO. You're going backwards.

Maybe if you explained what you're trying to do it would make more sense.
