I would really suggest that you replace the servo wire, it's pretty cheap and easy to do. Also, you have got to replace that molex/tamiya battery connector, those will heat up and melt with good batteries and high draw motors.
Actually, once I've got the configuration of the car all done and have driving it a few times to make sure it all works well, I shorten as many of the wires as I can to make it look cleaner.
I think i have a spare servo somewhere , glad it's easily replaced mind you. Is that something i'd be able to do or do i need to pop to the shop?
what about getting a thicker gauge wire just on the motor would that help because that's about the only thing i think i could do?
I'd love to be able to replace and do some of the things you guys have mentioned but tampering with connectors and soldering are things i'd be no good at , wish it would just work nice straight from the box lol
