I need a cheap way to get more power. I'm not sure if I want brushless because of haveing to get 2 speed controls. Is there a way to get some bigger motors in the stock ips fans? Or should I just rip them off buy some cowlings and put some johnson 250's in it?

depends what edf-50s you have. You can always upgrade to the 5 blade units or go for the uprated motors that will handle more cells(read 3 cell lipo)

(1) Is your battery powerful enough? On full throttle you should get 8~9 Amp.
(2) Is your ESC good enough? It needs to handle 8~10 Amp continuous.
(3) Is your electrical connectors good? The stock GWS/BEC/JST red connector is only good for a few Amps. At the 8~10Amp level for the stock motor to develop full power, the small connectors simply robs away a lot of power and turns them into heat that often melt the connector.
Really, many cases it is NOT the motor, it is small components in your power system that is underperforming.
Moving to 5 blade using the same motor only give you 1~2 gram more thrust but almost 2 Amps increase in current, not good.
Moving to the BH high voltage motor and 5 blade is a way to reduce Amp draw, but power is the same or slightly less.
