I got my daughter a new bright monster truck similar to the jeep to stem her curiosity from my nitros.
I took it apart in an attempt to help you solve the problem and the drive motor is hard wired directly from the logic card
which is both an esc and reciever.
Now judging from the design and what you have stated so far. it sounds like it might be an issue with your transmitter.
maybe the pot for the forward in your transmitter is shot. unfortunately I can't aid with diagnosing the TX, as my GF lost the TX for the monster truck during her last er um 'bash' with my daughter.

I purchased my son a New Bright Rock Crawler for his birthday. Took it out one time, and it ran fine. Charged the battery for a second run, and it will not go forward. Has reverse, and steering, but forward is dead. It won't even try to move forward so it seems like a short somewhere. I have adjusted throttle control, and channels but still nothing. It's only 2days old. Toys R Us wont take it back, and to send it to new bright i will have to pay shipping, and wait over 8weeks for a new one, and they don't Guarantee the same model will be available. I pretty much out of options except to fix it somehow. I know this RC is low level compared to the awesome rig's i see on this site, but i was hoping someone could give me some direction into what the problem could be. Thanks for any help you can give me. My son and i will greatly appreciate it. Thanks
