Which cells you plan to run?
5000? 4500?
Where you plan to ran? Race, bash, Speed runs?
compare weights of cells.
For track I'll bet on 8XL with 4S on MM
4S-weight bit less and safe for MM
maybe even 9XL on 4S
Feiagos are hot and be ready to play with gearing!
Actualy no mater what feigao you take sooner or later you will change this motor anyway for better one.
Also take look on MedUSA MR-036-060-2000V2-5 some of guys have great success. It runs cool and have plenty of power throw buggy!
