Hi Buddy, I had a similar experience like you. I gave away my new ! trx4 Bronco for a used UDR. The steering servo was already broken as i received the UDR from shipping. That was sad. I had to replace it. But now i am happy with the car. I have a collection of rc cars. But the x maxx and the Infraction are still the best in my opinion. I hope, your udr ist running good now. Best regards from Germany and sorry for my poor english. 🙋
Something simmilar happend to my arrma mojave 6s, my motor started smoking and became very hot and when we found the problem that was pretty sad, we've burned the motor.
It did run freely I completely ripped out the old drivetrain and replaced it with a new one when I got it and it was my first time driving it so the motor was just bad from when I bought it I didn't replace it when I got it
@FreddieHowe-wy5om Thank you very much. I read and try to respond to every comment I get. I love reading all the positive feedback. And I'm happy to answer questions about other stuff than rc.
