Ofna DM1 Spec Brushless Build

I bought dangerwr's DM1 on the 8th of this month. I am ready to get this build laid out on the table. I should receive it Tuesday. I am going with the MMM 2200kv and a Neu Electronics 5500ah 4s 35c lipo. It should do just fine for me. I will be in the smaller parking lots racing and drifting. I thought about trying the 2 speed for speed runs. Any input from you pros would be helpful.
