ups and downs of diff brushless systems

[paintballer1331]

ok cool so if i get the feigao and the 12020 it wont cog too much?? also if im using some 6 cell gp3300s from radio shak charging it up with the 977 charger what will be my runtime with this setup?

i also have a set of ib3800s so im not really sure if there is going to be a HUGE diff in the gp330s and the ib3800s the ib3800s are like 30 bucks more for a set so is 30 bucks more worth it?
