bought a new b44 buggy

[chris_trcc]

just bought a b44 buggy after selling my b4. as im going to be doing the north east regionals. just wondering if anyone be kind enough to point me in the right direction on setting the buggy up. which is the better speed control novak gtb /4.5 motor, which was used in the b4. or i got a nosram matrix evolution which never been used. and dunno how reliable they are. also been told the b44 got a weak spot which you can modify from fibrelite but dunno what it is,

cheers
