I've got it!!! Lets all go back to using Tamiya (molex) plugs!!! Those were great, why did we ever stop using those, its not like they melted or anything...?

Don't use that. It'll probably melt from the amperage of an RC system since it's only rated for 15A.

If you can't solder you should check these connectors out. Not only do they insulate the wires, but they also have a solder ball in the center that is easily melted by a heat gun.

I recently had experience with these. They were included with a Yoshimura fender eliminator kit for my Grom.

I'm curious about those because it's clearly a low melting point solder, but I'm not sure how well it would hold up in an R/C application. It's possible the solder would melt from the current going through it but the shrink might hold the wires together and keep the connection through the liquid solder. For a crawler it would probably be fine and never melt, but anything else I would be concerned. We've had proper solder joints come unsoldered just from the current.

Not sure if that was sarcasm or not, but I definitely melted a Molex connector and it was on a 1/18th scale buggy.

Very good point! Let me know if you do any testing with them.

A crimped connection with conductive grease would be the best connection overall, the mechanical pressure between conductors is fantastic for conductivity and the grease keeps it from corroding. Soldering is good enough for most RC needs though, and is more convenient for the home hobbyist.

Don't need grease if you use the heat shrink sleeve crimp connectors. Just crimp and heat, the connection is permanent and sealed. These are the only type of crimp butt connectors and terminal ends that I use any more.

This is sad, good God man buy a $20 soldering iron and learn a new skill! It's so easy even a cave man could do it.

I've seen corrosion get places it shouldn't and ruin wires. I never ever crimp without a nice coat of grease. even dielectric is better than none.
