Garson, we need to know the NAMBA FE classes run in your area in order to set up the MM to be legal for racing. I have used several different setups in my Mean Machine with good success, it is a very versatile hull.
A good setup for
P Offshore is a Feigao 9XL motor, a Castle Hydra 120LV controller (or equivalent), and two 2S LiPo packs with a minimum of 5000mAh capacity/30C rated. With an m645 prop this runs in the high 40s and is a lot of fun. There are a lot of different motors/controllers you could use, some more expensive than others, some faster than others.
A good setup for
LSO is either an SV27, BJ26 or UL-1 motor, an SV27 or UL-1 controller and two 2S LiPo packs with a minimum of 3700 mAh capacity/20C rating. Speeds will be mid- to high-30s. This is the most economical setup.
If your hull is one of the "damaged" ones Aeromarine sold, remove the radio box and drains, and plug all the holes except the necessary ones. The hull is the radio box, it is sealed with hatch tape. I assume you have some R/C boat building experience.
I'll attach a few photos of my MM, you can go to the following threads to see what others have done with their MMs.
