Once I can afford it, I want to put a MMM and a Neu 1521 in my Losi Muggy and I am wondering if the 1D will run cool enough. My 1515 1.5D is a little lower KV and it runs perfectly, but I just want to make sure I'll be OK before I dish out the money for it. If it will work, what gearing should I run for 40 series or Maxx wheels?
