You should be pretty happy with the power of your 1512 in a buggy though. Are you using 4s batteries?
Yes I am going to. I don't have any packs for this thing yet.
The 1.5D is 3200 kv. So I couldn't run bigger packs if I wanted to. But that's mainly why I got it. I wanted the maximum destruction with the smallest pack I could use.
