mbx5t vs a baja 5b?

Thanks for the replys, your on topic dont worry. the guy is getting a ported 27 kit that i doubt he will get any more then 3HP to the ground (clutch slippage, spool up time, tune, gas mixture ect.) and now i defiantly know i will win. Im going to buy FlightPower batteries, 1 4s , 5s and a 6s all 5000mah. What run time do you think i could get out of this? And is this a good choice to get 1 of each pack? (money is not an issue, i am getting a nice, fat settlement soon)
