Just a thought, but if I cut the wires on the battery and connect the esc between the cuts, how safe is it to charge the battery with the esc attached.

Why hasn't someone invented a small bridge that can be placed in between the battery, NanoTwo and ESC instead of cutting the cables.

Also just realised that i'm probably going to need a on/off switch because of the blade. So can I get a link to a part and some advise as to where to splice it into the diagram. :D


I figure once the diagram is 100% done, ill have a working spinner by christmas.

You mean a Y lead?

I put switches in by cutting the red wire on the nanotwo and connecting it, the brushless ESC red wire also attaches to the switch. then splice in the brushless ESC black wire to the black wire on the nano two. You should NEVER have to cut the wires on the battery.

What is this "Y" lead you speak of? :) Clearly I know nothing 8)

Can you advise on where I can get this. Iv had a quick look on hobbyking and the y leads are for servos and not power.

Ill work on the updated diagram tomorrow when words start to make sense :)

Damn, was hoping you weren't going to say that.

Right so a smaller diagram will be required inside the main one to show the y lead.

Okay then, where do I start with the y lead. Im assuming that its not done completely from scratch and that its a few cables with the right connections that get cut. (Reminds me I need to learn the names of the connectors :D )

Right diagram has been updated. I've added in a zoomed section to see the Y part.

From what I understand, the wires are joined and connected to the original connector from the NanoTwo and use electrical tape to cover up the join.

Would the black cable from the switch connect in with the black from the NanoTwo and ESC?

The switch I have found is this http://www.robotshop.com/uk/sfe-on-off- ... witch.html , I think it will work unless you have other suggestions.

Your last diagram wouldn't be able to turn the robot off and the switch would short the battery. You want something more like this:

Also that switch would be huge, you want something more this size:

Ah, I see. My diagram wasn't that far off then :D

Do you have a link to where to get that kind of switch?

EDIT: would this switch be better - http://www.robotshop.com/uk/tamiya-mini ... h-2pk.html
