Brushless 501 reccomendations

[Colinevan]

My 501 is virtually built now, Im on the market for another brushless setup, I currently use a Novak GTB 5.5 in my zx-5 and am very happy with it. Iv upgraded to sintered and its now ace.

I can easily buy another GTB, however id like to know what other 501 owners are using. If im being honest the GTB is a little big as opposed to the Lrp and i think you dont need to run the fan with the Lrp.

Im quite happy with 5.5 power however id prob try a 4.5 now as it comes with a heatsink can etc. What would be the equivalent model would you say?

Thanks

Col.
