Default Micro Rock Crawler - HELP!

About a month ago I purchased a Micro Rock Crawler, my intention was to build a 1:24 scale version of my 1:1 TJ. I got a New Bright cheapo RC for the body, DP torsion chassis, aluminum skid plate...everything is coming together pretty nicely, UNTIL...

When I was putting things together, the orange wire came off the motor. While trying to solder it back on (my soldering skills aren't the greatest) the blue one came off. Ok, fun...finally got them both soldered on, plugged things in, turned everything on (and yes, in order - TX, then RX). First thing is the steering slammed to the left and locked there, then the wheels started spinning full-throttle in reverse! I'm pretty sure i didn't reverse the motor wires. I even tried binding the receiver to the transmitter, same thing happened.

I read a post on here that Losi's servos aren't the best quality...but I've maybe run 6 charges on the battery through this before I started my scale build. Are they that bad or is something else going on?

Any help would be greatly appreciated. I'm okay with paying for a few after-market hop-ups, but to have to replace stock parts when this thing is pretty much new??

Doesn't sound like a servo issue. You didn't have your truck turned on when you soldered the motor wires back on did you? (Stupid question) Make sure you have all your TX settings back to zero and try re-binding again. Also, if the steering is slamming one way and staying, did you have your servo horn off and not put it back on at centre?

Nope, everything was off - even had the battery disconnected - when I was soldering. And I didn't even take the servo horn off, just the plug from the motor to the esc (easier soldering without the extra weight). All the TX settings are pretty close to where they were before I started working on it, and I've tried re-binding several times, all with the same outcome.

I'm stumped! Not to mention getting frustrated...

does it do it when you`ve disconnected the motor or the servo. it could be a faulty receiver
