Can a bad connection cause heat?

With the traxxas connectors, you need to make sure that you did not solder past the little line on the flat gold piece. If you did, they will not snap together. I use a small flat blade screwdriver to pus on the gold connector to pus it into place. Out of about 50, I have had at least 10 that are really hard to snap into place.

For the record, I prefer deans, mainly cause the trx plug is much bigger.
