I do not have a .5 class truck, but from what i have seen, the MM motors seem to heat up in them. The 3500kv VXL seems to work great, Though most here like the 1506 neu's or 50mm medusa's around 3300kv
Work because i gotta, play because i wanna
People here hate Nitro, I love it. I start it, run it about 50 ft from me and it dies, I go after it. Perfect exercise
