Default Battery and Esc Connection

Im kinda new to the whole R/C hobby thing and im still learning. I wondered if any of you experienced people would know the answer to my question. What are causes of esc and battery connections getting extremely hot and melting plastics together? i would think that something like this wouldn be natural. Thanks.

It really boils down to the industry standard connectors that are included w/ a lot of RTR vehicles, batteries and speed controls. They're commonly known as "Tamiya" connectors and they flat out suck. These have been the standard for a long time and are very inefficient compared to high quality connectors, like those made Deans. If you're running anything more powerful than a stock motor, chances are they won't be able to handle the increased amp draw and will eventually melt together. You'll never see a serious racer using Tamiya connectors. I would really recommend upgrading to Deans Ultra Plugs. I've been using them for a long time and have never had any problems with them. They're WAY more efficient and can handle any motor/battery combination with ease.

Yeah, they need to be soldered on. It's not the most difficult job, but if you don't have any experience soldering you should probably get someone who knows what they're doing to help.

Your local hobby shop. Look for one that specializes in R/C cars. They may charge you a fee to do it, but it shouldn't be much (if anything). I would avoid Radio Shack.

i wish there was a hobby shop that specialized in R/C cars around here, it kinda makes me mad too, would it be okay if i went to a local hobby shop that didnt specialize in R/C cars but they still have them?

If they sell the Ultra Plug, chances are they will be able to solder them for you.

actually, any place that does electric rc parts, no matter what, should be able to solder. As for why the connectors melt is because of the high resistance of the connectors, if you were to switch to deans, you would notice ur esc or motor getting hotter because more power is going to it.

depends on how hot, if the motor gets so hot that you cant touch it, yes i would drop a few teeth on the pinion. Also, i would suggest a heat sink for your motor too.

I have the TA04-R chassis so i dont have an option to put a heatsink on it, and i don't know if the motorplate counts as one or not.
