2 trucks, 2 combos, what recipe?

[RC-NUT]

Hey guys,

I have 2 projects at the moment and I'm trying to install the right components in the right truck for the best performance.

What I have:

Trucks:
1. Savage X converted.
2. Muggy roller.

Components:
1. CC 1518
2. CC 1717
3. CC MMM
4. CC MMP
5. Hitec 5645 servos
6. 4s LiPo's.

I plan on buying 5s or 6s Lipo's depending on the combos. I have a feeling the MMP may not be sufficient for either. The Savage currently has the 1518 on 4s and it's fun but lacking speed. Torque and runtime are fine. I borrowed a friends 6s and WOW it woke up.

Thanks.

MMpro should be ok on a light Savage on 4s geared sensibly - 6S or heavy gearing or a heavy truck then get another MMM
