Great motor, works well good speed and pretty quiet, I've used in my traxxas rock crawler and it performs effortlessly.

I burnt out my original Dynamite motor in my ECX Torment 2WD. I searched for quite a while to find a replacement and I'm glad I found this one. This motor was a direct fit replacement, took me less than 5 minutes to change. Original motor was a 15T so I didnt want to go any higher because I wanted to maintain the speed I was used to. So, after a quick warm up and a 30 minute full throttle run in a parking lot I'm happy to say that the motor didn't burn out. I'm very pleased with the speed. (I'll try to post a video I made) Sounds like a jet:) I've read that someone said the motor was loud.. It's no louder than most Brushed motors. Definitely worth the buy and if this one does burn out I will be buying the same one again.
