This is great. I've really enjoyed the jr I bought too. It is a blast and has been durable for me too once I swapped in a sidewinder micro, spektrum radio and hitec mini servo. I've yet to break anything and had definitely run it into some walls and posts.
I experienced some serious heat when I put the rock racer tires on my score truck. The gearing was wrong but it's faster and gets through tall grass better.
I too have looked for another motor. Looking forward to hearing about your experience with those
Looks like the Can Am version that Horizon are running with has a dynamite 37T motor. I’ll grab one of these as a spare but the stocker is still doing well.
