I love the reliability of Traxxas models.
My Monster Mutt is bone box stock, and it has been used twice daily, sometimes three times a day, every single day, since last November 7 when I unboxed it to use to exercise my dog with it. I use 5000 mAh 2S 35C batteries in it.
Well, the other day something finally broke. I lost the steering servo. What happened, was the main output shaft broke off three teeth.
I have a few left over servos that have mostly burned out PC boards, so I grabbed a main shaft gear out of one and rebuilt the servo in the truck. back in business.
