Brushless Revo or brushless CRT .5 help is appreciated

[GorillaMaxx360]

buy him saying the three piece motor mount and cf chassis i believe he meant he was going to use the vantage chassis and the nitro to Brushless motor mount i believe. this would mean that he would probably want to go with just one pack one one side of the revo so like one 4s pack, or he could make a battery holder on each side to accommodate 2p2s lipos.
