Shortening wires on esc and bec
 

Shortening the wires on my 2 x fxr's and bec to the receiver cause any problem other then being to short for other installs on other things. like to do it so not to have to wrap them up and to make crawler lighter.

You can cut them or coil them. I'd coil them so that you are able to use them on other projects. Here are some example;

How did you get your wires to coil like that? Looks very nice.

every body just wraps them around a screw driver to get that telephone coil, that's old school "thumbsup" .........bob

Gorgeous wire job"thumbsup"

After coiling them I like to shrink some heat shrink tubing over them. It keeps them from uncoiling and neatens up the install. Simply pull the wire out and cut off the heatshrink when you're ready for another install.

Coil is the best way to go, I do all of mine like that. never thought about heat shrink....good idea.
