at least jason will have to do battery management. with the brushless, it is not really a concern. with 3800, and the 3 star, you should have plenty of juice.
4 of us ran that same setup (lrp/ready) at last years region 9 regionals and one of us ran a 10 double. the guys with the 10 double did have to do some battery management, but we were all right there in speed.
maybe this will help, but the brushed motor won out at the end.
