On/off Switch Between Bec And Receiver

[TAZ-NZ]

I run a Hitec DCX reciever and Hitec EZX-R Pro ESC with BEC, can I safely place a on/switch switch in the cable bewteen the ESC & the receiver to cut power from the bec to the receiver. (Please note there is no seperate bec cable with this setup). I want to run a remote power switch that is in a more accessible spot on, so I don't have to remove the car body to disconnect the battery or switch off the ESC.

Generally, the on/off switch on an ESC simply cuts the positive wire of the lead that connects the ESC to the receiver, and this connection is usually done on the PCB inside the ESC's case..

I see no problem with cutting the positive wire in the lead from the ESC to receiver, and connecting a switch in there.. BUT...

One thing that you may consider is buying a 300mm long servo extension lead to place between the ESC lead and the receiver and then connectiong the positive wire of that through a switch. That way you wont be doing any physical damage to the leads on your ESC, (eg for warranty) and it may give you any additional length you may require to put the switch in the most suitable location.. It will also allow you to remove the ESC (to put in another car for example) and not having to worry about removing the switch.

Cheers.

Thanks for that, that's what I thought but just want to check to be sure.

Yeah I planned on using a servo extension or something similar like you suggested, it seamed the most pratical way to do it without a extra work.

Thanks again.

You can do it, but the only problem is that until you disconnect the battery from the ESC the ESC is still Live.

Yeh, thats a good point (oops I didnt think of that). The ESC would still be live if the battery was connected, and as such it would be discharging the battery whenever it was plugged in...

It may be a better idea to just buy an ESC that has a remote switch, and just lengthen the wires to the switch.

Every ESC is always live when the battery is connected, even when the switch is off as the switch just connects the 6v feed from the ESc to the receiver.

What you are doing is exactly the same way ESCs are wired up.
