brushless build

[gash100]

ok its time to go brushless so i ordered the kershawdesigns conversion kit today ,now from what ive read this will work with my 3speed gearbox and let me use the stock brake set up,but would i be better of buying a flux gearbox,as this will let me use the brushless brake and reverse and reduce drag as well .also will the flux gearbox fit into the standard savage tvp's ,i was looking to use the mamba monster combo
