Questions about upgrades

[slo4sho]

I just ordered a Seaking-180amp esc, predator 4082-1600k and a X447 prop.

1. What lipos should I use? I have the 5000 25C 11.1
2. Should I upgrade the flex shaft?
3. Should I use 5.5 connectors or bigger?
4. Is the x447 good or should I go different?

Don't think 25c will cut it I use 45-90 nano tech for my spartan. Had some stock blue turnigy 25c 2 of 4 puffed. I only have EC5 on batts and 6mm bullets on motor, if you got bigger you can use them (http://forums.offshoreelectrics.com/...or-5.5-bullets).
