Problems with PF connectors of the RC Buggy Motor

[Variteck]

Hi everyone, I ask for help with a problem with the PF connectors of an RC motor (Chinese version of course). As shown by the photos, after a few minutes of use on the Rally Car 42077 powered by Buwizz in ludicrous mode, the plastic swelled and "melted".

This resulted in a bad or impossible connection with the extension wire it was connected to. I also had a hard time disconnecting the motor connector from the extension cable connector as they were almost stuck together.

Has anyone encountered similar problems?
Should I definitely give up on ludicrous mode when using this engine?
Would I risk melting the plastic of the Buwizz if I attacked the Rc Motor directly?

I've seen that happened on my 3D printer where high electric current was going through a loose connector. It arc'ed and melted the plastic connector. Make sure your chinese connector has a soild electrical connection with your PF connector. 

With great current comes great melt.

You'll probably do better using an original Lego PF lead. As above, the problem is high current and a loose or otherwise poor connection.

Thank you guys.

  I'll take a couple of Lego cables, and try to replace the damaged PF connector of the RC motor with a new one.thankk you guys.
