with the cost of motors and Top cells its way cheaper to go 13.5 B/less one the best combos is the fusion Logic 13.5 and ESC for £85then of coures you will need ONE lipo pack not half a dozen
The B/less scene is going Stock ESC . . . So no timing or boost so cheap running still
I have about 9 motors sitting in me workshop and all have lost there edge
so £8 X 9 motors . . . Brushless is way cheaper
But dont get us wrong the G2 and 4cell will be around for ages yet
