Yes it will work just fine. No Mods. Just plug n play. My Mamba Max takes 4s with just BEC and fan (No caps, but it would help running 15 volts) on the CCNeu 2650 (Amp Hog). So I know you will be more than fine with lower kv and lower voltage. The MM is the Champ on 3s with no mods... (4s with mods, I've heard 5 or 6s with serious mods.)
Maxx - FLM, MMM, CD Med.36x706s
