yep, that's my team's name, currently only me and my school friend

. before knowing combat robotics, we have been pretty successful in somekind of block moving competition, we reached 2nd in 2010 and 3rd in 2011. but now, we wanted to try combat robotics.
here's my CAD Design of the robot(on Google Sketchup 8):
http://s1198.photobucket.com/albums/aa458/coolnael/?action=view¤t=firestorm6.jpgand here's the stuff that we will use on the robot:
2 BaneBots RS-540(drive motor)
2 P60 16:1 gearbox
1 Sabertooth 12
2 BaneBots Wheel, 2-7/8" x 0.8"(orange version)
1 Victor 884(weapon ESC)
1 BaneBots RS-550(weapon motor)
5 Anderson PowerPoles
1 PowerEdge 2200mAh 11.1V 3S Triple Cell 30C LiPoly Pack
and the Team Losi Intelligent LiPo Balance Charger.
i the stuff i'll buy is good? and do you recommend any other Lipo battery charger other than the Team Losi one?
and, can all of you guys assist me in this build?
by the way, the robot will be named XRG ad it's a hobbyweight.
